California/Railroads/Passenger

This is now a "sub-wiki" to California/Railroads, from which it was split off due to length. As this subordinate wiki remains large (>100 kilobytes) even after that split (and continues to grow), this wiki may split, too (again, into Northern and Southern, most likely).

Main article: California/Railroads. See also California/Railroads/Active for freight rail (as opposed to passenger rail), noting that significant portions of this have split into distinct wiki: Northern California Active Rail and Southern California Active Rail.

California Passenger Trains, expressed as route=train, route=subway, route=light_rail, route=tram and route=monorail relations, with active, regular passenger rail traffic. There are also railway=funicular, railway=narrow_gauge, railway=miniature and amusement park rail.

Passenger Trains tables are "believed complete" and "largely correct," though the Tourism section has several text-based-only notations saying these routes are "being researched." If you find a train (relation link, Review Status...) that needs to be added, updated or improved, whether to the map or to this wiki, please do so!

Trains

A subset of California's freight mainline and branch rail support passenger traffic with route=train relations. These offer passenger=national (long distance, usually overnight), passenger=regional (medium distance "intercity," both interstate and intrastate) and passenger=suburban ("commuter rail") passenger services. All national-network Amtrak™ route=trains have passenger=* tags, with a value of either international, national or regional (but not suburban, urban or local). Additionally in California, route=subway, route=light_rail, route=tram, route=monorail and route=funicular relations are found. Often blurred with passenger=suburban route=trains (spanning multiple counties, usually characterized as "heavy rail") is larger-city-scale route=light_rail, often tagged passenger=urban. California route=light_rail and route=tram relations always have passenger=* tags (usually urban and local, respectively) and while commuter route=trains are tagged passenger=suburban, not all route=trains have a passenger=* tag, as some tourism/heritage/museum trains do not (on rail tagged usage=tourism). But if so — as some tourist lines do offer a modicum of useful local passenger service, simply by being a passenger line serving their stations — these route=trains are tagged passenger=local.

Passenger trains' tracks, stations and platforms are properly collected into route=train relations, or relations tagged route=subway, route=light_rail, route=tram or route=monorail when those are the underlying rail infrastructure. A convention in this wiki: public_transport:version=1 routes are in table column headers as type=route and public_transport:version=2 routes are in table column headers as type=route_master. However, if a table has a type=route_master column AND a type=route column, the latter are not public_transport:version=1 routes, they are the member route relations of the type=route_master super-relation.

Passenger train routes in the following national, regional, suburban, urban and local sections and tables are "mostly Complete," at least to a rudimentary stage of public_transport:version=1. Let us continue to improve these data to public_transport:version=2, with a type=route_master super-relation, fully directional routes and all platforms. See Capitol Corridor℠ routes, which emerge as public_transport:version=2 examples — but while these relations have stations and platforms, more platforms are needed. For a model v2 route with exemplary station and platform members see 1405414 1405414 of the Maryland Transit Administration. A goal is for all passenger train routes to become fully compliant with public_transport:version=2, each identically-tracked train with its own route and precise platform locations. If you find a train, route (relation link, Review Status...) that needs to be added, updated or improved, whether to the map or to this wiki, please do so: Map Your Train Ride!

California's State Transportation Authority (CalSTA) calls "intercity" what OSM (here) calls "regional" rail. Likewise, CalSTA calls "regional" what OSM (here) calls "suburban" or "commuter" rail. The connotations of "urban" rail by both CalSTA and OSM are about the same.

Amtrak operates intercity passenger trains in the contiguous United States: many intrastate / interstate passenger=regional trains and all interstate, passenger=national (long distance, overnight), highspeed=yes trains and passenger=international trains (serving Canada); see the full OSM Amtrak wiki table. Two subsets are here as routes serving California, five passenger=national routes by Amtrak proper, and three passenger=regional routes operating jointly between Amtrak and three "more local/less statewide" so-called "joint powers authorities," partly funded by the California Department of Transportation (Caltrans) Division of Rail as an entity known as Amtrak California:

Try OpenPublicTransportMap (OPTM): it displays passenger rail in route=train relations. At closer zooms, OPTM also displays route=light_rail, route=subway, route=tram, route=monorail, route=funicular, route=bus, route=trolleybus, route=aerialway and route=ferry with colors similar to ORM. Please compare and contrast ORM (rail infrastructure) and OPTM (passenger routes) with OSM's Transport layer which rather simply displays "any and all rail" (railway=*), though not disused or abandoned rail, and at closer zooms, route=bus. Here was another rail renderer which displayed rail-based passenger routes with their colour=* or color=* tag (no longer functional).

Colors are Amtrak passenger=national routes = blue. As California's national Amtrak routes are all lengthy overnight trains, these are assigned darker (web safe) blues: California Zephyr (DarkBlue), Coast Starlight (MidnightBlue), Southwest Chief (#000066), Sunset Limited and Texas Eagle (Navy).

Amtrak California (passenger=regional) trains (CDTX)

The Capitol Corridor Joint Powers Board (CCJPB) consists of two representatives from each of the eight counties in The Capitol Corridor: Placer, Sacramento, Yolo, Solano, Contra Costa, San Francisco, Alameda and Santa Clara, represented by Placer County Transportation Planning Agency, Sacramento Regional Transit District, San Francisco Bay Area Rapid Transit District, Santa Clara Valley Transportation Authority, Solano Transportation Authority, and the Yolo County Transportation District. The CCJPB is also supported by the two metropolitan planning organizations in The Capitol Corridor – the Metropolitan Transportation Commission and the Sacramento Area Council of Governments.

The LOSSAN Rail Corridor Agency (LOSSAN) “is composed of elected officials representing rail owners, operators, and planning agencies along Amtrak's Pacific Surfliner corridor between San Diego and San Luis Obispo. The objective of the agency is to coordinate planning and programs that increase ridership, revenue, reliability, and safety on the coastal rail line from San Luis Obispo to Los Angeles to San Diego.”

The San Joaquin Joint Powers Authority (SJJPA) enables local and regional agencies throughout most of the San Joaquin Corridor (Bakersfield - Fresno - Modesto - Stockton - Sacramento - Oakland) to assume the administration and management of Amtrak's existing San Joaquin Rail Service from Caltrans' Division of Rail.

Caltrans, through its Division of Rail, provides support to California statewide intercity (passenger=regional) rail services via CCJPB, LOSSAN and SJJPA. This support includes planning and financial assistance for capital and operating expenses, consistent with its mission to “provide and promote intercity passenger rail services while improving, expanding, and integrating all rail service into California's transportation system." As a result of the "more local" administrations of CCJPB/LOSSAN/SJJPA and newer model of Caltrans funding, "Amtrak California" branding and livery is less prominent.

A Phase 1 extension from San José (Diridon) south to Gilroy (+49 km) and Salinas (+60 km) is expected in the 2020s for a new length of 238 miles (384 km). Infill stations at Pajaro/Watsonville Junction (to serve Santa Cruz) and Castroville (to serve Monterey) are Phase 2, with no revenue service date specified, as Monterey Branch is disused / abandoned and Santa Cruz Branch is Class 1 speed (rehabilitation to Class 2 is "medium-term" but lacks funding), limiting freight to 10 MPH and occasional tourism trains to 15 MPH as it rehabilitates (in preparation for its own local passenger service between Pajaro and Santa Cruz in the 2030s). Service to Salinas would correspond with Amtrak Coast Starlight® passenger=national services and Caltrain passenger=suburban service (after Caltrain extends from Gilroy). The Capitol Corridor is the third busiest Amtrak route in the USA, moving 1.4 million passengers annually between San Jose and Auburn.

Planned improvements/extensions as part of the Valley Rail Project include two new daily round-trips to better connect San Joaquin Valley travelers with the Sacramento Area and extensions to Altamont Corridor Express (ACE) service between Sacramento and Merced (remaining anchored at Stockton, with ACE service continuing to San José). New stations would include Lodi, Elk Grove, City College, Midtown, Old North Sacramento and Natomas/Airport (in the Sacramento Extension; both San Joaquins and ACE) north of Stockton, Oakley Station west of Stockton on the way to Oakland and Modesto, Turlock/Denair, Merced, a relocation of the Madera station and transfers to Fresno south of Stockton. The first Valley Rail trains are anticipated to operate in 2025, with completion expected by the end of 2027. As "initial interim" revenue service of California High Speed Rail service between Merced and Bakersfield begins circa 2030, Amtrak's San Joaquins will then eliminate service between those two stations, effectively "ending at Merced" (and no further south). OKJ→MCD→OKJ and SAC→MCD→SAC will become new Valley Rail routes (independent of CAHSR), superseding those segments on San Joaquins, while remaining passenger=regional; passengers continuing to Bakersfield from Merced will transfer at Merced to High Speed Rail. As Valley Rail's local/state funding partnerships are unclear, it is not known if/how a fully implemented Valley Rail will affiliate/brand as/with Amtrak California; TBD.

Colors for Amtrak California passenger=regional routes = orange (color of California poppy, state flower), ocean blue and khaki (appearing as light golden/sandy yellow). California's state colors are blue and gold.

There is a nascent (Phase 0 completed, Phase 1 is 2022-2023) initiative called Link21 apparently sponsored by Capitol Corridor and BART interests, though with wide public input and participation by Bay Area transportation agencies. It envisages a circa-2040 "Megaregion" (of the San Francisco Bay Area) rail network with physical infrastructure and service improvements including a (second trans-bay, in addition to BART) Link21 Rail Tunnel connecting San Francisco's Salesforce Transit Center (future California High Speed Rail terminus) with the East Bay (crossing San Francisco Bay easterly and northward to cross BART's M-Line, east of West Oakland, continuing north to Emeryville on UP's Martinez Subdivision). It was denoted here.

California High Speed Rail (passenger=regional) trains (CAHSR), under construction

In June 2015, California began construction of the USA's first dedicated high-speed rail, centered around Fresno (abbreviated CAHSR). Expensive and controversial, CAHSR is the nation's largest public works project. Original Phase 1 envisioned San Francisco - Los Angeles - Anaheim, though this is now scaled back with a new governor. New Phase 1 (known as the Central Valley Segment, CVS) is Merced - Fresno - Bakersfield, 171 miles. 119 miles of CVS right-of-way from Madera (S of Merced) to Shafter (N of Bakersfield, at Poplar Avenue) are under construction to complete CVS. Segments of this infrastructure are ways tagged railway=construction + construction=rail + usage=main + highspeed=yes + name=Construction Package #. Largely complete in OSM, now tracking construction; OpenRailwayMap (ORM) displays CAHSR railway=construction as red dashed lines for Madera - Fresno - Shafter and CAHSR railway=proposed as red dotted lines in the far N and S of the CVS, S of Merced and N of Bakersfield (was San José and Burbank).

In February 2019, Governor Gavin Newsom’s first State of the State Address (SotSA) scaled back CAHSR, redefining the project. Newsom said California will focus on finishing rail now under construction. Original Phase 1 (including Central Valley to Silicon Valley and Bakersfield to Burbank) estimated completion by 2029, or 2033 should all of Original Phase 1 fund. Read High-Speed Rail Authority CEO Brian Kelly’s post-SotSA Statement here: “The Governor has called for setting a priority on getting high speed rail operating in the only region in which we have commenced construction — the Central Valley. We are eager to meet this challenge and expand the project’s economic impact in the Central Valley. Importantly, he also reaffirmed our commitment to complete the environmental work statewide, to meet our 'bookend' investments in the Bay Area and Los Angeles and to pursue additional federal funding for future project expansion. We welcome this direction and look forward to continuing the important work on this transformative project.” The Authority's 2023 Project Update Report (February 28, 2023) states a goal is to open the CVS for initial "CAHSR Interim" revenue service (Merced - Madera - Fresno - Kings/Tulare - Bakersfield) by "the end of 2030" with a "25% schedule contingency — creating a 'schedule envelope'...to 2033" (based on FRA guidance). As of the 2023 Project Update Report and because of yet-to-be-identified construction funding, neither Phase 1 North (Merced - Gilroy - San José - San Francisco) nor Phase 1 South (Bakersfield - Burbank - Los Angeles - Anaheim) have scheduled opening dates; updates are welcome here. Base cost estimate to complete (Original) Phase 1 is $106,163,000,000, with a low of $88,545,000,000 and a high of $127,933,000,000. Current funding is ~$28,000,000,000; ~80% state, ~20% federal.

Environmental clearance is required for design work to be completed, then (funded) construction bids can be sought, won and construction can begin. Original Phase 1 environmental clearance is largely complete: the Authority has environmental clearance on 422 of 478 miles of right-of-way (88%) between San Francisco and Palmdale and between Burbank and Los Angeles. Environmental clearance on all of Original Phase 1 is now due on Palmdale - Burbank, Los Angeles - Anaheim by 2024-25, with completion by 2025-Q4 of all environmental documents for all 478 (512) miles of Original Phase 1 as a stated goal in the 2023 Project Update Report. 478 infrastructure miles include Bay, 4th & King, Pacheco, Sierra, Desert and Tonga Subdivisions and the "to Merced" southerly segment of Capital Subdivision: 144 + 1 + 5 + 151 + 129 + 28 + 20 = 478 miles. As service "to Merced" includes through-the-wye Pacheco Subdivision and double-traversal of Capital Subdivision "to and from" Merced, traveling 40 miles on the otherwise (more directly, skipping Merced) 6 miles between CP Merced and CP Divide, add 34 miles to an Original Phase 1 route serving Merced: 512 route miles on 478 infrastructure miles. By late 2030 (2033 at the latest), initial "CAHSR Interim" revenue service (Merced - Madera - Fresno - Kings/Tulare - Bakersfield) is scheduled to run the 171 miles one-way in 82 or 83 minutes, trainsets completing round-trips (Merced - Bakersfield - Merced) in less than 3 hours.

An excellent "Systemwide Alignment Schematic" is available detailing CAHSR Subdivision boundaries, stations, speed limits, control points, MOWFs, yards and specific track configurations for Original Phase 1. As these data are public domain (meet OSM's ODbL requirements), let's incorporate even more sensible elements of them into our map! (e.g. tunnels, bridges, viaducts as description=Tunnel #1). During 2022-3 on CVS' active construction segments, many landuse=construction polygons, related roadwork and other construction mapping has emerged along this rail corridor, from Madera to Fresno to Shafter. New and updated OSM mapping is encouraged as construction continues and eventually completes.

CAHSR's enabling legislation (up to and including 2008's Proposition 1A) requires that Original Phase 1 be completed and "in service" before construction begins on Phase 2 (Merced - Sacramento & Los Angeles - San Diego). Phase 2 segments are medium- to longer-term-future oriented and (like Phase 1 North and Phase 1 South) have no projected date for completion.

Name	route=railway	Route	Notes
CAHSR Phase 1, as newly proposed: CVS as "early operating segment"	Initial Capital Subdivision (Wye at CP Divide north to Merced) 14757833 14757833 Sierra Subdivision 7739486 7739486	Merced - Central Valley Wye - Madera - Fresno - Kings/Tulare - Shafter - Bakersfield	What is now Sierra Subdivision was the "Original Phase 1" relation, as CAHSR has scaled back to the 2019-Q2-defined "Phase 1 CVS." With Governor Newsom's scaled back CVS' "early operating segment" (171 miles) and initial construction (119 miles) underway, more specific OSM updates are welcome. 119 miles of Madera - Fresno - Shafter are tagged railway=construction as "Construction Packages" (public works contracts; here, CP1, CP2-3 and CP4). The northerly 34 miles (Merced - Central Valley Wye - Madera) and southerly 18 miles (Shafter - Bakersfield) are tagged railway=proposed as these are funded for design (a $41 million Madera-to-Merced extension design contract to Stantec Consulting Services Inc. and a $44.9 million Shafter-to-Bakersfield extension design contract to HNTB, both scheduled to be completed before 2025), but have not yet gone to solicit construction bids. Here, no newer CPs have yet been offered for bid nor won by any specific construction contractor, so change tags on these 34 and 18 miles from railway=proposed to railway=construction after design work completes, construction bids are won and construction begins (expected mid-2025) by tagging new CPs as they are known to be under construction with CP5, CP6, etc. in name=* tags of railway=rail elements. Taken together (34 + 119 + 18 = 171 miles), these ways are believed correctly tagged and why this row is green, though, please more precisely tag any incorrectly tagged railway=construction or railway=proposed segments if known to improve OSM data as more up-to-date. Not all auxiliary tracks, sidings, crossovers, bridges, viaducts, cuttings, embankments, etc. are properly denoted in the ways, as some may be unentered, under construction or completed: please update! Construction Package 4 (CP4) is nearly complete (but for a culvert relocation), CP1 and CP2-3 are expected in 2026, track and signals in 2027, with CVS expected to enter testing with the first train delivery in 2028. Station construction is expected to commence in 2026, completing in 2029. 2029 is also scheduled for the completion of CVS as "early operating segment" infrastructure proper, completion of Static Testing and completion of Dynamic Testing. Following completion of Trial Running, the Authority's "highest goal" is to begin CVS / "early operating segment" (Merced - Fresno - Bakersfield) revenue service by "late 2030" (2033 at the latest, given the FRA contingency). Merced is CAHSR Phase 1 "early operating segment's" northern terminus to correspond with extensions to ACE route=trains, partially funded (as newly-branded Valley Rail) to reach ACE's / Valley Rail's planned Merced southern terminus circa 2026. This segment includes CAHSR's Sierra Subdivision (Bakersfield - Wye at CP Divide) and the southern portion of its Capital Subdivision (Wye at CP Divide - Merced).
CAHSR Phase 1 North, as originally proposed	Planning relation 9466656 9466656 Bay Subdivision (stub) 15570754 15570754 Pacheco Subdivision 15570755 15570755 4th & King Subdivision 15573877 15573877	(Merced) - Central Valley Wye - Gilroy - San José - San Francisco	The northerly remainder of what was Phase 1 after the Initial Operating Segment was shortened as it was newly proposed in early 2019. Tagged railway=proposed, because of the project's redefinition and funding levels, timing moves to more medium-term (after the "early operating segment" opens for revenue service between 2030 and 2033). From Merced to and including the wye itself and westerly to Gilroy is new alignment (there will be tunneling), then from Gilroy northwards, CAHSR shares UP Coast Subdivision and JPBX Peninsula Subdivision to San José and San Francisco: CAHSR's / Caltrain's CalMod project (the "northern bookend") has completed electrification between Tamien Station (south of San José Diridon Station, near UP/JPBX ownership change) and San Francisco, fully environmentally cleared for CAHSR. CalTrain now offers fully electrified passenger service between San Francisco and Tamien stations, achieving 110 MPH (177 km/hr) speeds with its Express service, allowing CAHSR to share "blended service" here. From San Jose - Gilroy - Wye is environmentally cleared, this segment awaits completion of design, then construction bidding happens and actual construction can commence. Gilroy - Wye segments are now included in the Bay Subdivision relation (stub): eventually, rail infrastructure elements north of Gilroy with improved specificity now approximately represented in the Planning relation should introduce into the Bay Subdivision relation, then as the Bay Subdivision completes with actual CAHSR infrastructure elements in OSM (essentially, ways tagged railway=construction or railway=rail rather than railway=proposed), the Planning relation deprecates and should be deleted. This segment includes CAHSR's Bay, Pacheco and 4th & King Subdivisions.
CAHSR Phase 1 South, as originally proposed	Planning relation 9466653 9466653 Desert Subdivision (stub) 15573920 15573920 Tonga Subdivision (stub) 15573919 15573919	Bakersfield - Burbank - Los Angeles - Anaheim	The southerly remainder of what was Phase 1 after the Initial Operating Segment was shortened as it was newly proposed in early 2019. Tagged railway=proposed, because of the project's redefinition and funding levels, timing moves to more medium-term (after the "early operating segment" opens for revenue service between 2030 and 2033). S of Bakersfield to Palmdale and from Lancaster to CP Sheldon (Pacoima, N of Burbank) is new alignment (there will be tunneling), then shares (as "southern bookend" plans to electrify continue on) UP Valley Subdivision from Burbank to CP Fletcher and again as new alignment through Elysian Park three miles to Los Angeles Union Station. Finally, parallel alignments along River, San Bernardino, (except around Norwalk/Santa Fe Springs) and Orange Subdivisions complete the route to ARTIC in Anaheim. Both the Bakersfield - Palmdale and the Burbank - Los Angeles segments are environmentally cleared. Palmdale - Burbank should be environmentally cleared now and Los Angeles - Anaheim by 2024-Q4. The "southern bookend" of California High Speed Rail is underway with Phase A of the “Link Union Station” project, completion expected in 2028. Metro CEO Stephanie Wiggins called this "a key funding milestone for the [high speed rail] bookend project here in Southern California." Phase B (Segment 4, to complete the Concourse Area) remains unfunded. Regarding further completion of the "southern bookend," it remains to be seen how far along an electrification project prepares right-of-way adjacent to and including Metrolink Green and Yellow lines from Burbank to Glendale to Los Angeles. This segment includes CAHSR's Desert and Tonga Subdivisions (stubbed at their respective termini); when Subdivision relations complete with actual CAHSR infrastructure elements, the Planning relation deprecates and should be deleted.
CAHSR Phase 2 North	9466655 9466655	Merced - Modesto - Stockton - Sacramento	Medium- to longer-term-future oriented. Believed fully though quickly and roughly entered into OSM. Displayed as red dotted lines at zoom levels ≥11 in ORM. There is no projected date for completion, however, by 2030 the Authority intends to advance this segment to 30% design so that construction can continue to progress if and when funding is provided. This segment includes the northern portion of CAHSR's Capital Subdivision (north of Merced).
CAHSR Phase 2 South	9466654 9466654	Los Angeles - San Bernardino - Riverside - San Diego	Longer-term-future oriented. Geographically unknown in places, there remain a number of alignments under consideration. Only partially entered into OSM (precise route data in Los Angeles, San Bernardino, Riverside and San Diego Counties are not fully known and hence, less complete). Around West Covina, Temecula/Murietta and Escondido/Rancho Bernardo/Mira Mesa displayed as red dotted lines at zoom levels ≥11 in ORM. Might be removed from OSM, as Phase 2 South appears unfunded (barely funded?) into the foreseeable future. Call this the roughest of sketches, only "partially there" or even "barely there" in OSM. There is no projected date for completion, however, by 2030 the Authority intends to advance this segment to 30% design so that construction can continue to progress if and when funding is provided. This segment includes CAHSR's San Jacinto Subdivision.

A proposal for All Aboard Florida-owned "Brightline West" high-speed rail between Las Vegas and Apple Valley / Rancho Cucamonga is in OSM as 14039872 14039872, unrelated to CAHSR.

Commuter (passenger=suburban) trains

Largely connecting suburbs of multiple counties in their networks, passenger=suburban "commuter" trains are shorter-distance than passenger=regional intercity trains, but longer-distance and faster than passenger=urban and passenger=local trains. These route=train (ACE, Caltrain, COASTER, Metrolink, SMART) and route=subway (BART) relations are tagged passenger=suburban: "Trains that have frequent schedules to satisfy the needs of work commuters...largely state-run/city-run services for connecting a metropolitan area to its central city." These (usually "heavy rail") trains are publicly-owned and operated by multiple California counties as "joint powers authorities," except COASTER, publicly-owned but serves only San Diego County and ACE, where tracks are leased from UP and operations are contracted (by a multi-county JPA) to Herzog Transit Services. Some (ACE extensions to Modesto and Merced branded as Valley Rail, Metrolink Antelope Valley northwards...) could grow lengthy enough to become newer passenger=regional services, especially as in the future these might include "express" (sometimes called "skip stop") trains to more quickly connect their most-distant endpoints.

BART / Bay Area Rapid Transit (BART)

Main article: Bay_Area_Rapid_Transit

BART is a largely-electrified rapid transit system in the San Francisco Bay Area: six lines (mostly heavy rail, all of it electrified, with some short monorail and Diesel Light Rail segments) on 131.4 miles (211.5 km) of track with 50 stations (21 surface, 14 elevated, 15 subway) in five counties. Systemwide, there are approximately 32 miles (51 km) of aerial track; 70 miles (115 km) of track at grade and about 28 miles (45 km) of subway track. Most BART infrastructure is FTA-defined "heavy rail" tagged railway=subway, so BART is in the "Commuter" section, as BART's systemwide geographic span is similar to other Commuter rail networks in California, including BART's newer infrastructure like Coliseum – Oakland International Airport line (railway=monorail) and BART to Antioch extension (railway=light_rail, FTA-defined "Diesel Light Rail"). All lines are tagged network=BART and the network-wide relation is 8477436 8477436.

BART Silicon Valley Phase II Extension Project intends to complete in 2037, adding four new stations to the Green and Orange lines: 28th Street / Little Portugal, Downtown San José, Diridon and Santa Clara in a subway alignment, achieving (with Caltrain & Amtrak correspondences at Diridon and Santa Clara, respectively) much more frequent Bay Area rail service that "rings the bay."

Revenue service is expected in 2037. Phase II was in Design and Engineering during 2020-1, infrastructure in OSM is a relatively rough sketch: proposed or under construction as a route=railway towards a public_transport PTv1 route=subway (no longer under construction when completed), then a segment of Green and Orange PTv2 route relations.

Caltrain / Peninsula Corridor Joint Powers Board (JPBX)

Caltrain offers three services (Express, Limited, Local) from San Francisco through the San Francisco Peninsula to San José and commuter trains (morning, late afternoon) to and from Gilroy. It services over 30 stations in three counties on 77 miles (124 km) of track. At Millbrae, connects to BART, a passenger=suburban-to-passenger=suburban correspondence. At San José Diridon, connects to ACE (to Stockton, becoming Valley Rail), another passenger=suburban-to-passenger=suburban correspondence, as well as corresponding with Amtrak™ passenger=regional and passenger=national services, making Diridon Station a major rail hub. Electrification between San Francisco - Tamien Station (CalMod project) is complete as the "northern bookend" of CAHSR Phase I as Caltrain now (2024-Q4) offers fully electrified passenger service achieving 110 MPH (177 km/hr) speeds on its Express (was Baby Bullet) service's Class 6 track, to be shared in "blended service" with California High Speed Rail, debuting passenger revenue service circa 2030. There are medium-term plans (mid-2030s?) to extend Caltrain passenger=suburban service south of Gilroy to Monterey County (Pajaro/Watsonville, Castroville/Monterey, Salinas), corresponding with planned light rails in Santa Cruz and Monterey Counties, with possible Capitol Corridor passenger=regional service extending south to Salinas (late-2030s?) to correspond with Amtrak™ Coast Starlight passenger=national southerly service to San Luis Obispo, Ventura, Los Angeles, Orange and San Diego Counties. Salinas and Gilroy become key correspondences in a statewide rail network, as are San José Diridon and Bakersfield today and Stockton and Merced becoming with the emergences of Valley Rail and California High Speed Rail.

Note: Caltrain's so-called "6-trains" are not trains at all, they are "bus bridges" which are in the Schedule as 6XX "train" routes to temporarily replace train service with bus service (see Rail replacement bus service). These are used when there are unanticipated or planned closures, accidents or construction.

SMART / Sonoma-Marin Area Rapid Transit (SMART)

Sonoma-Marin Area Rapid Transit (as SMART) uses Diesel Modified Units for motive power on infrastructure tagged railway=rail + usage=branch.

Larkspur north to Sonoma County Airport (46 miles / 73 km) is the currently-active portion of the 70 mile / 113 km "Larkspur to Cloverdale" corridor for this passenger=suburban service between Sonoma and Marin counties, known as SMART Phase 1. This enables passenger connections via Larkspur Ferry Terminal to San Francisco Ferry Terminal, Gate C (pedestrians walk 100 m to Muni E, F; 200 m to California Street Cable Car; 250 m to BART Embarcadero). Northerly, SMART offers SMART passengers free bus service from Sonoma County Airport station to Windsor, Healdsburg and Cloverdale. SMART Phase 2's 3 mile northern extension from Sonoma County Airport to Windsor is expected Spring 2025 and to Healdsburg and Cloverdale by 2027, completing passenger service on the entire corridor.

ACE / Altamont Corridor Express (HTSX), becoming part of Valley Rail

The ACE corridor serves 10 stations in three counties (San Joaquin, Alameda, Santa Clara) over 86 miles (138 km) of track, from Stockton to San José. Service is managed by the San Joaquin Regional Rail Commission (SJRRC), with operations contracted to Herzog Transit Services using AAR assigned reporting mark HTSX on tracks owned by Union Pacific (UP) and a few miles of Caltrain (JPBX) tracks. At San José Diridon, connects to Caltrain, a passenger=suburban-to-passenger=suburban correspondence.  News in 2017 reported southeastern expansion from Stockton through the Central Valley to Modesto/Ceres, +30 miles (+48 km) and Merced, +35 miles (+57 km), now branded as "Valley Rail." With news of these extensions (bringing line distance to 241 km/150 miles, over the 160 km/100 miles fuzzy threshold between suburban/commuter and regional rail) and newer service north of Stockton to additional cities including Lodi, Elk Grove and Sacramento (sharing the latter with Amtrak California), ACE grows from a single "commuter" passenger=suburban line into what may become California's fourth passenger=regional rail service (complementing Amtrak California's current three). With the Valley Rail Project (including improvements to San Joaquin passenger=regional service), ACE will become two-line service linked at Stockton: existing passenger=suburban ACE line to San José and developing lines southeasterly serving Modesto/Ceres (ACE Extension Phase 1) and Merced (ACE Extension Phase 2) by 2026, plus Stockton northerly to Sacramento later. Thus, ACE begins a merge/blend into Valley Rail. Merced is a key Bay Area link as the present northern terminus for (the Central Valley Segment of) Phase 1 of California High Speed Rail, expected to begin revenue service in late 2030 (2033 at the latest).

In October, 2023, a base order of $80 million for the first four trainsets (with options for up to 25 additional trainsets that can be used throughout California) was made with Stadler Rail, Inc. to deliver the first zero-emission, hydrogen intercity (passenger=regional) passenger trains in North America, furthering California’s standing as a world leader in clean transportation, expected to primarily operate between Merced and Sacramento on Valley Rail services that will also connect with the early high-speed rail service between Merced and Bakersfield. These hydrogen trains will also be demonstrated on corridors throughout the state in coordination with intercity (passenger=regional) and regional (passenger=suburban) rail partners.

Initial Valley Rail trains are anticipated to operate by 2025, with completion expected by the end of 2027, intending to eventually harmonize with Phase 1 CAHSR revenue service by late 2030.

Metrolink / Southern California Regional Rail Authority (SCAX)

Metrolink is a commuter rail network by authority of five counties in Southern California as SCRRA (reporting mark SCAX). Six counties are serviced if Oceanside at the end of the Orange line is counted (San Diego County is not part of SCRRA). Metrolink offers seven service lines and 64 stations operating on 388 miles (624 km) of track, about 534 route miles (859 km).

Los Angeles County Metrolink-Metro and Metrolink-Amtrak® correspondences are:

§ A CAHSR station is planned to be built a short walk from North Burbank's Metrolink station.

The "southern bookend" of California High Speed Rail has begun with the $423.3 million funding of Phase A of the “Link Union Station” project, completion expected in 2028. Metro CEO Stephanie Wiggins called this "a key funding milestone for the [high speed rail] bookend project here in Southern California." Phase B (Segment 4, to complete the Concourse Area) remains unfunded. Regarding further completion of the "southern bookend," it remains to be seen how far along an electrification project prepares right-of-way adjacent to and including Metrolink Green and Yellow lines from Burbank through Glendale to Los Angeles.

COASTER / North County Transit District (NCTC)

COASTER offers service along the San Diego County coastline, from Oceanside to San Diego. It services 8 stations on 41 miles (66 km) of track. Owned by North County Transit District (NCTD), operated by Bombardier Transportation (since 2016). At Oceanside, connects to Metrolink Orange, a passenger=suburban-to-passenger=suburban correspondence.

Cross Valley Corridor (proposed)

 Cross Valley Corridor is an 80-mile (130 km) proposed passenger rail service in California's Central Valley to connect Visalia, Hanford, Porterville and other nearby cities anchored by California High Speed Rail's planned Kings-Tulare Regional Station. In middle planning stages, it will not open for revenue service until at least the 2040s, so it is far too soon to enter into OSM as a route=train relation. Infrastructure (as route=railway relations) will include Exeter, Goshen and Hanford Subdivisions, all part of California/Railroads/Active/Northern#San_Joaquin_Valley_Railroad_(SJVR) owned by Genesee & Wyoming, as well as a short (~1 km) segment through Goshen of UP's Fresno Subdivision, where SJVR now has trackage rights.

North Valley Rail (proposed)

The North Valley Rail Project will bring passenger rail service northward from the Natomas area in Sacramento (linking ACE/Valley Rail) to the City of Chico in Butte County, with stops in Plumas Lake, Marysville-Yuba City, and Gridley. Bus connections will link Oroville with the proposed Gridley station, and the Natomas station with the Sacramento International Airport. The right-of-way will be existing trackage of the Union Pacific's Sacramento Subdivision. The Lead Agency is the Butte County Association of Governments (BCAG), a Joint Powers Agency of the County of Butte, the cities of Biggs, Chico, Gridley, and Oroville and the Town of Paradise. Initial revenue service is expected to begin in 2028 (two daily roundtrips), expanding to four daily roundtrips in 2031.

City, Light Rail (passenger=urban) trains

Most California route=light_rail relations are tagged passenger=urban (as are heavily-travelled route=tram relations; it is usually correct to tag route=tram and route=monorail relations with passenger=local due to shorter distances — please use discretion). Some (underlying infrastructure) members of railway=light_rail (e.g. Muni) are ways tagged route=tram (or vice versa). Note that OpenRailwayMap (ORM) displays railway=monorail infrastructure as light_rail (green), while OpenPublicTransportMap (OPTM) displays monorail explicitly. Two lines are FTA-defined "heavy rail" (Los Angeles' Metro B Line (Red) and Metro D Line (Purple)): these route=subways are included in this City, Light Rail section as part of LA Metro's single-county network of trains. LA Metro's rail is largely above-ground route=light_rail (Downtown sections are underground), but also include these two exclusively route=subway routes and an aerialway route=monorail route (LAX Airport Metro Connector, in later construction phases as of 2024-Q4). SMART had similar odd tagging of light_rail + suburban, now tagged "suburban train." This OT query might help visualize: all relations in California tagged route=light_rail and passenger=urban, noting exclusion of LA Metro's B Line (Red) and D Line (Purple), as they are not tagged route=light_rail, but being exclusively underground, are tagged route=subway, more "rapid transit" or "Metro" (FTA-defined "heavy rail").

San Diego County surfs an edge between whether underlying infrastructure used mainly by light rail should be tagged railway=rail or railway=light_rail: electrified San Diego Trolley lines (elements of Blue and Orange) and Escondido Subdivision elements (SPRINTER, Diesel Modified Units / DMUs) are tagged railway=rail, even as both railway systems predominantly support route=light_rail passenger services (during the day and evening), while also supporting freight service at night / in the very early morning hours (0200 - 0330). This caused / causes some vacillation on tagging between Escondido and Oceanside, while on San Diego Trolley lines, many segments of Blue south of Old Town and most segments of Orange to Santee remain tagged railway=rail + usage=branch where freight service is shared with light_rail passenger service. Consistent tagging on both of these systems maybe has / maybe has not settled, but the confusion is understandable as there are elements of SPRINTER which are "not typical light rail" (e.g. using DMUs instead of electric motive power), while San Diego Trolley's Blue and Orange lines frequently get confused by many OSM editors because of the mixed traffic. Unambiguously, San Diego Trolley's Green Line is exclusively passenger=urban railway=light_rail, with no freight traffic, temporally-separated or otherwise.

Sacramento Regional Transit District (SCRT)

RT operates a light rail system spanning the Sacramento area that is currently the eleventh busiest in the United States. Similar to San Diego Trolley in its largely-street-running-in-Downtown tram-like character, this wide-area urban system is denoted railway=light_rail throughout. There have been edits which tag "strictly tram as tram" (as Muni L, N in western suburbs of San Francisco) causing some vacillation between railway=light_rail and railway=tram.

Blue Line	Light Rail	533	9248096 9248096	Complete v2 route.

Plans are underway (as of 2024-Q1) to complete environmental review for an extension of the Green Line to Sacramento International Airport. The way in OSM is tagged railway=proposed proposed:railway=light_rail.

San Francisco Muni / Metro (MUNI)

Muni / Metro combines light rail, tram, historic streetcar, cable cars and a Central Subway into San Francisco's passenger rail network, providing rail-to-rail connections with BART, Caltrain and (circa 2030) California High Speed Rail. Some segments are light rail in dedicated right-of-way, some are street-running tram-like trains, some are substantially tunneled or underground. Market Street Railway is a partner on E and F Lines, restoring historic streetcars. Underlying infrastructure is either railway=light_rail or railway=tram, not railway=subway, even for underground segments, which are tagged tunnel=yes plus a negative-value layer=* tag. All Muni / Metro rail routes are tagged passenger=urban.

VTA Light Rail / Santa Clara Valley Transportation Authority (SCCT)

VTA Light Rail serves San José and northern Santa Clara County with 41 miles (65 km) of light rail network on three lines (Blue, Green and Orange). Downtown San José and other segments can be considered tram-like (street-running trains) though the system is denoted railway=light_rail throughout. With BART service to Milpitas station, VTA Orange Line allows BART connections to Caltrain at Mountain View, providing contiguous "rings the bay" passenger rail service on three networks: BART (change trains to VTA Orange at Milpitas), VTA (VTA Orange from Milpitas to Mountain View) and Caltrain (change trains from VTA Orange to Caltrain at Mountain View), BART again from Caltrain at Millbrae (to Milpitas or elsewhere).

Tagging (on these largely viaduct and bridge segments) transitioned from railway=proposed to railway=construction. Trains will run primarily in the center of Capitol Expressway with elevated tracks crossing Capitol Avenue, Story Road and Tully Road with stations at Story (, Ocala?) and Eastridge. However, there is no known funding source to extend this light rail any further south from Eastridge to South San Jose.

Los Angeles County Metropolitan Transportation Authority / LACMTA / MTA / Metro (LACM)

Los Angeles Metro, rail portions of which are also known as Metro Rail, operates combined rail rapid transit (subway, light rail, monorail at LAX by 2025) in Los Angeles County. Metro operates eight rapid transit lines: six light_rail/subway (dedicated right-of-way) and two bus rapid transit (on abandoned rail right-of-way: old Pacific Electric Red Car line and old Burbank Line plus I-110; Metro G Line (Orange) and Metro J Line (Silver), respectively, see Transitways). All Metro rail and Busway rapid transit routes are tagged passenger=urban. Rail service offers 10, 12, 15 or 20 minute headways, depending on line and time-of-day.

2017 news revealed a plan, and a 2018 SCAG update of the Norwalk C Line (Green) Extension Study, while paused as of April, 2018, is in the process of identifying and evaluating feasible alternatives for this potential 2.8 mile rail link. It could be 2052 before this Extension opens for revenue service.

2019 news indicated that by the 2028 Summer Olympics, four light_rail and four Busway rapid transit lines will be added, totaling 16 rapid transit lines. Some planned lines and assigned letters are: Arroyo Verdugo / L Line; North San Fernando Valley / N Line; Sepulveda Pass / Q Line; Vermont / R Line and West Santa Ana (from Downtown Los Angeles to Artesia) / S Line.

Continuing updates as Metro grows and reconfigures should track each other both in the map and in this wiki section, especially to accommodate new lines before the 2028 Summer Olympics. New line between Pacoima and Van Nuys has begun as the East San Fernando Valley Light Rail Transit Project.

Crenshaw / LAX to connect Metro E Line (Gold) at Expo/Crenshaw to Metro C Line (Green) at Aviation/Century near LAX under construction, partial service now with K Line (Pink, below). Metro C Line (Green) begins a new operational pattern (the "C-3" one-year pilot study) near LAX, northerly and southerly. The southern branch of Metro C Line (Green) will operate with Redondo Beach trains continuing through El Segundo and Aviation/LAX, east to Willowbrook/Rosa Parks (becoming a modified Metro C Line (Green) and perhaps Metro ? Line (Olive)). The partially-complete Crenshaw / LAX Project blends westbound Metro C Line (Green) trains from Norwalk turning north after Aviation/LAX along Aviation Blvd. to terminate at Expo/Crenshaw, "partially new" Metro C Line (Green).
Metro D Line (Purple)	Subway	805	7935318 7935318	Not-quite-complete, public_transport v2. Union Station - Wilshire/Western. The child relations for each direction are missing platforms and benefit by including these members, please. Map Your Train Ride! Section 1 (of 3) of the Metro D Line (Purple) Subway Extension is under construction, revenue service scheduled 2025-2027. From the current terminus at Wilshire/Western, this 15 km westward extension includes seven new stations, three in Section 1: Wilshire/La Brea, Wilshire/Fairfax and Wilshire/La Cienega. Section 2 extends further westward with two more stations: Wilshire/Rodeo in downtown Beverly Hills and Century City/Constellation (construction began in 2018). Phase 3 will extend to Westwood/UCLA and Westwood/VA Hospital, construction began in 2019.

Metro K Line	Light Rail	807	14669757 14669757	Not-quite-complete, public_transport v2. K Line connects Metro E Line (Gold) at Expo/Crenshaw (its northern terminus) south to Metro C Line (Green) at Aviation/Century near LAX, where Metro C Line (Green) now continues to its southern terminus at Redondo Beach. See Metro C Line (Green) above and below for re-routing notes about Metro ? Line (Olive). With completion of Airport Metro Connector (2025?), a new infill 96th Street Transit Station will allow transfers to Airport Metro Connector to LAX terminals. A future phase might extend this segment (a re-routed Metro C Line (Green)) north to Metro D Line (Purple) near or at Wilshire/La Brea, then to a new northern terminus at North Hollywood to connect with Metro B Line (Red).
Metro ? Line (Olive) Re-routing ("C-3")	Light Rail	?	8215031 8215031	Under construction as a type=route relation, not a master relation. After completion of Crenshaw / LAX Project (initially, K Line), Metro C Line (Green) begins a new operational pattern (C-3) near LAX, northerly and southerly. The southern branch of Metro C Line (Green) will operate with Redondo Beach trains continuing through El Segundo and Aviation/LAX, east to Willowbrook/Rosa Parks (may become Metro ? Line (Olive)). The nearing-completion Crenshaw / LAX Project blends westbound trains from Norwalk to Aviation/LAX (remaining Metro C Line (Green)), then turning north along Aviation Blvd. to terminate at Expo/Crenshaw, becoming the new Metro C Line (Green).
Airport Metro Connector	Monorail / Automated People Mover	?	6666780 6666780	Somewhat incomplete stub relation, not a master relation, alignment is fairly accurate, may need additional double-tracking in places. In 2018, the Airport Commission approved a 30-year $5 billion construct-and-operate contract. The nearing-completion Crenshaw / LAX project (to become what might be described as "a northern branch" of Metro Green Line, becoming the "new" Metro C Line (Green)) will involve westbound Metro C Line (Green) trains turning north after Aviation/LAX, traveling along Aviation Blvd. This will allow transfers to the fully-automated people mover Airport Metro Connector at a new infill 96th Street Transit station, transporting riders to LAX terminals 1-8 and the Rental Car Center. Upon completion (2025?), remove construction=* tags and assure all stations are present and correct.

San Diego Trolley, Inc. (SDTI)

The San Diego Trolley is a light rail system operating in the metropolitan area of San Diego and serves 62 stations, with 65 miles (105 km) of routes. Infrastructure in the Downtown area can be considered tram-like (street-running trains) though the system is denoted railway=light_rail throughout. The relation column (Route Master) points to a type=route_master relation, even though the children relations are more v1 than v2: they are missing many platforms, except for Orange, which is fully v2. Please, Map Your Train Ride!

Service Line	Route	Trains	type=route_master	Status
Sycuan Green Line	Light Rail	530	9946502 9946502	Incomplete; public_transport v2; missing many platforms, though has some.
Orange Line	Light Rail	520	9946503 9946503	Complete public_transport v2, awesome!
SDG&E Silver Line	Light Rail		9946498 9946498	Incomplete; public_transport v2; missing many platforms, though has some; please fill in Trains column. Rolling stock are restored vintage/historic/heritage streetcars. Limited service: only Tu Th, 0952-1352 and Sa Su, 1052-1522.
UC San Diego Blue Line	Light Rail	510	7572438 7572438	Somewhat complete; public_transport v2, however, additional platforms still need to be added to the two child relations (north and south). The (newer) Mid-Coast infrastructure (from Old Town to La Jolla) needs its electrified=* tags properly set.

Since 2011, a new Purple Line is planned (for 2035) to expand this Trolley network. In addition to the small "inner loop" Downtown (Silver Line), a $15.56 billion project might extend southward from Sorrento Valley and La Jolla through Kearney Mesa into Mid-City, Orange Line correspondence at Euclid, central Chula Vista and terminating in San Ysidro (back to itself on Blue Line) to form a large "outer loop" of Blue and Purple. The way is in OSM tagged maxspeed=110 mph, name=Purple Line, operator=MTS, proposed=subway, proposed:railway=subway and railway=proposed, an unusual set of tags, though these make sense seeing as how SDMTS changed initial categorization of this corridor from light rail to heavy rail. Early planning phases of a subway ("metro" or "rapid transit" or "heavy rail, high-speed" or "partly underground"), Class 6 rail. How much of it will be below ground versus how much of it will be ground-level or aerial track? How will it be electrified? These and other design aspects are presently (2024-Q1) unknown to OSM. Improve if you can!

SPRINTER / North County Transit District (NCTD)

SPRINTER is a light rail system operating between Oceanside and Escondido in northern San Diego County. It services 15 stations on 22 miles (35 km) of track with 30 minute headways. SPRINTER is not electrically powered, using Diesel Modified Units (DMUs) for locomotion by NCTD's contract operator, Bombardier Transportation. Due to its shared right-of-way with freight trains serving Escondido industrial customers, SPRINTER platforms had to be set back from the tracks a sufficient distance to provide enough room for what were Watco / Pacific Sun employees riding on the sides of freight cars. (BNSF is believed to now own the right-of-way). The passenger trains are not FRA-compliant for operation in association with freight trains and therefore freight operations on the route are not permitted during passenger operations (they are temporally separated). For this reason some publications refer to this line as light rail but it does not conform with the usual understanding of that term. However, OSM tags the elements of the Escondido Subdivision which are used by SPRINTER with railway=light_rail rather than railway=rail + usage=branch (these latter two tags remain on track used exclusively by BNSF (was Watco / Pacific Sun) at night / early morning hours to serve industrial customers SE of the Escondido Transit Center). There have been edits which tag "rail as rail" (not light_rail) causing some vacillation between railway=rail and railway=light_rail. The FTA categorizes this "diesel light rail."

SPRINTER	Light Rail	399	12417807 12417807	Complete; public_transport v2; yeah!

Arrow / SBCTA Redlands Passenger Rail (SCAX)

A 9 mile (14.5 km) passenger service rail extension called Arrow on the San Bernardino-Redlands Passenger Rail Corridor opened by SBCTA (part of Metrolink) in 2023. Extending Metrolink service to the San Bernardino Transit Center, this service uses 3 diesel modified units and 1 electric modified unit plus 1 Metrolink locomotive-hauled coach on BNSF trackage as host railway (low-volume temporally-separated freight service by BNSF continues on a portion of the host route=railway subdivision). Stops include Downtown San Bernardino, Tippecanoe Avenue, Esri Station, Downtown Redlands and University of Redlands. A potential further phase would expand trackage in a loop to Highland and San Bernardino International Airport before returning to downtown San Bernardino. Perhaps this moves to Metrolink section / table depending on how and whether Arrow retains identity or becomes more Metrolink-branded (as "Metrolink Arrow?" or "Arrow Express?"); to be determined.

Service Line	Route	Trains	type=route_master	Status
(Metrolink) Arrow: San Bernardino Transit Center - University of Redlands Station	Train	3 DMU + 1 EMU: SNB -> Tippecanoe Avenue -> Esri Station -> Downtown Redlands -> University of Redlands (and return to SNB with same stops)	14728552 14728552	Tagged passenger=urban despite being a route=train because of the short length (9 miles).

OC Streetcar / Orange County Transit Authority (OCTA), under construction

A 4.15-mile (6.68 km) tram line under construction in Orange County, California, w:OC Streetcar will serve 10 (at opening), 11, or 12 stations (perhaps in later phases), its termini at Santa Ana (Regional Transportation Center) and Garden Grove (Harbor Transit Center), operated by the Orange County Transportation Authority (OCTA) as a curbside, street running system in Santa Ana, while west of Raitt Street will be in dedicated rail right-of-way (part of railway=abandoned Paramount Industrial Lead from old Pacific Electric Red Car early-20th century transit). Please double-track where extant, bridge-work may not be reflected. Revenue service expected in (August?) 2025.

Service Line	Route	Trains	type=route	Status
OC Streetcar	Tram	?	8438643 8438643	Under construction; entered as a route=railway, not a route=light_rail or route=tram. As revenue service begins, please change railway=construction tags to railway=tram, fully improve stations/platforms and create new railway=tram public_transport:version=2-compliant relations tagged passenger=urban.

Airport-style Monorail, People Mover, Automated Guideway Transit (passenger=local) trains

The Federal Transit Administration (FTA) categorizes these as People Mover or Automated Guideway Transit, which include monorail and light rail guideways. Some underlying infrastructure (for example, SMF APM) is railway=tram. Note that OpenRailwayMap (ORM) specifically displays railway=monorail infrastructure as light_rail (green) and OpenPublicTransportMap (OPTM) displays route=monorail distinctly.

AirTrain (San Francisco International Airport, SFO) (????)

A free-of-charge, fully automated people mover at San Francisco International Airport (SFO), connecting terminals, BART, the rental car center and most parking garages. This system is "landside," (outside of SFO's "sterile area"), so after this transportation system's use, departing airline passengers require TSA screening to enter "airside" (the secure area of the airport).

See Airport Metro Connector; to serve Los Angeles International Airport (LAX). This is substantially an elevated railway=monorail. Now (2024-Q1) in later phases of construction, revenue service is expected by 2025.

Inglewood Transit Connector (????), planned

Inglewood plans a $1B automated people mover as an elevated proposed:railway=monorail to link Metro Rail's Crenshaw Line's Downtown Inglewood station with Inglewood's developing sports and entertainment district (The Forum, SoFi Stadium), scheduled to open by the 2028 Summer Olympics. The 1.6-mile-long single segment segment of railway=proposed is entered as a logical stub.

Tourism, museum, heritage and historic (possibly passenger=local) trains

Underlying railway=* infrastructure elements are tagged usage=tourism. It may be correct to tag these route=train, route=tram and route=monorail relations with passenger=local due to shorter distances, though please use discretion: distinctly "excursion" services shouldn't get this tag, but some tourism services may provide a measure of local-oriented passenger transportation and can rightly be tagged with passenger=local. Here is an Overpass Turbo query which may be helpful. Note that OpenRailwayMap (ORM) specifically does NOT display railway=rail infrastructure tagged usage=tourism or railway:preserved=yes, however, OSM's Carto (Standard) layer does display these.

Color semantics

About the (status) colors in the (Route) Name and Service Line columns

Amtrak routes all have "no color" in their type=route_master column because they are completed v2 routes.

Green means that the route's TIGER data in OSM are fully reviewed. This strongly implies that all other relation attributes are correct, but this isn't always strictly true; see Notes/Status column. Green does not conflict with active public_transport:version=* v1-v2 growth. Go!

Yellow means "only partially reviewed" ; additional volunteer work is needed to enter or correct additional route data (railway and/or train) into OSM. Yellow may also mean a route has a volunteer entering data, yet route ambiguities persist about what is actually correct.

Red means that "something" (often very little) is known about the route, so it is useful to put a row in the table about it as a placeholder, but it likely may be too early to create a route relation: route data are unknown, incomplete or route attributes are significantly missing.

About the (branding) colors in passenger=* and passenger-oriented Route columns

For route=train, route=subway, route=light_rail, route=tram these displayed (web) colors are intended to reflect real-world colors denoted by the transportation authority network, such as in printed, painted or otherwise visually branded materials directly associated with a particular route. For the Amtrak routes, a goal is towards more state/national agreement and completion. An initial example is that for Amtrak Cascades service in Washington state and Oregon, OSM's Amtrak wiki table and Mapzen's former transit-colours renderer (no longer functional) both display a closely matching shade of green, which in turn (by intention) better match livery of rolling stock found only on those tracks by that line and class of service. Similar early harmony among Amtrak and California/Railroads is underway, e.g. Capitol Corridor as orange, color of California poppy, the state flower and Pacific Surfliner as ocean blue. Color harmony, in motion.

About the colors and symbols in the Status and Notes column of Amtrak routes

Color and symbol legend: status of each route is indicated by a symbol, which describes the type of feature, and a color, which indicates the completeness of that feature in OSM. For more details, see Wiki Help. Meaning of symbols:

Symbol	Meaning
	Route status
	Stops status

The visual symbols are concise, and while originally designed for bus stops, also work well for train routes.

Base Code	NA	0	1	2	3	4	X
{{State Route|r=...|h=}}	- implies status unknown	- no part of route added	- route partly added (as relation)	- route mainly added, needs completing	- route relation complete (in view of 1 editor). Should be verified.	- route complete & verified by second editor. Please date.	- route does not exist in real world.
{{State Route|r=|h=...}}	- implies status unknown	- no stops added to relation	- some stops added	- most stops added, needs completing	- all stops added to relation (in view of 1 editor). Should be verified.	- route complete & verified by second editor. Please date.	- no stops in real world. Unlikely to be used without r=X as well.

The codes 0-4 are a logical progression, but they do not all have to be used in sequence. It is perfectly acceptable to go from 0 (nothing on map) to 3 (everything done in opinion of one editor). However, there should never be a jump to level 4. r=4 should only appear after r=3, and the same with h=3 & h=4, as this implies the relation has been checked by both the editor who completed it (level 3), and a second editor (level 4). Given these are different people, a jump up to level 4 from anything other than 3 is not possible.

In this wiki, this symbology is used as relations indicate where public_transport:version=1 is becoming version 2. The route_master column eventually will be fully populated with v2 relations (v1 routes upgrade to v2), the type=route_master column data acting as "entry point" into these Amtrak routes, type=route column linking to "directional" child relations.
