United States

Should highspeed=yes be tagged on US railway=rail elements between 80 mph (128 km/h) and 124 mph (199 km/h)?

No, I don't believe so. Most mainline rail, especially that owned by major railroads (where Amtrak® offers "conventional speed" passenger service) is  Class 4 track, with a passenger service maximum speed of 80 mph (129 km/h), often rounded down (for safety?) to 79 mph (127 km/h). While Class 5 track has a top speed of 90 mph (145 km/h) for passenger service and Class 6 track of 110 mph (177 km/h), we should reserve tagging highspeed=yes for railway=rail elements on Class 7 track (where passenger service top speed is 125 mph (201 km/h)) and above. Class 5 and Class 6 track simply aren't fast enough to tag highspeed=yes, Class 7 and above are. Portions of Amtrak's Northeast Corridor have Class 7 trackage, a few segments are the only Class 8 trackage in North America, allowing for 150 mph (241 km/h) passenger operation. The USA currently has no Class 9 track (220 mph (354 km/h)), although Amtrak undertakes test runs with Acela Express® trains at 165 mph (265 km/h) on Class 8 track. California High-Speed Rail now builds Class 9 track for speeds up to 220 mph (354 km/h). Stevea (talk) 20:05, 22 January 2019 (UTC)

No because that is not high speed, period. K2000 (talk) 19:42, 14 August 2023 (UTC)
