information sign

This page is a guide on how to tag signals of legal tramways in Germany as defined by BOStrab. This include actual tramways, light rail networks and subways. For normal and narrow gauge railways as defined by EBO resp. ESBO, please refer to OpenRailwayMap/Tagging in Germany instead.

Preamble

Although the BOStrab defines various signals which are more or less universally used, each operator can also use its own signals in addition to those as defined by BOStrab. Standard signals are prefixed with DE-BOStrab: but in order to differentiate local systems, the country prefix DE- and an abbreviation of the operator is used instead. For example, for Stuttgart it's DE-SBB:, for Hamburg it's it's DE-HHA: and for Hannover it's DE-UESTRA:.

BOStrab

Main signals (Hauptsignal, H)

H 0 A red light Stop
H 1 A green light Go
H 2 A green light over a yellow light Go with limited speed

It's important to know that main signals can also be used as distant signals. If they're purely used main signals, one use railway:signal:main:*, otherwise if it also serves as a distant signal, use railway:signal:combined:*.

For example, Go with limited speed can mean on some systems, that the next signal shows stop which makes it a main signal with characteristics of distant signals.

Main signal without characteristics of a distant signal

This section does not apply to Karlsruhe, Stuttgart, Hamburg und Hannover which use a different signalling instead.

Main signal with characteristics of a distant signal

This section does not apply to Karlsruhe, Stuttgart, Hamburg und Hannover which use a different signalling instead.


Distant signals for main signals (Vorsignal, V)

V 0 Two yellow lights Stop expected
V 1 Two green lights Go expected
V 2 A yellow light over a green light Go with limited speed expected

Distinct from driving signals (Fahrsignale) which show dots and letters as light signals.

Driving signals (Fahrsignal, F)

F 0 A horizontal white bar Halt
F 1 A vertical white bar Go allowed only straight forward
F 2 A diagonal to the top right pointing white bar Go allowed only to the right
F 3 A diagonal to the top left pointing white bar Go allowed only to the left
F 4 A white dot Stop expected
F 5 A white triangle which points downwards Fahrt freigegeben unter Beachtung der Abbiegeregeln nach § 9 Straßenverkehrs-Ordnung

Those signals can also appear as signs and not as traffic signals. Those signs are tagged with railway:signal:main:form=sign instead.

Signals which permit signal priority are often depicted as a glowing A and are tagged as railway:signal:main:PT_priority=requested;off.

Speed limit signals (Geschwindigkeitssignal, G)

Announcement of a speed limit (G 1a/b)

This signal announces a speed limit (change to a slower speed). The number in the sign times 10 equals to the speed limit.

G 1a A yellow triangle which points downwards with a white border and black number. If the space is limited, the triangle can point upward instead.
G 1b A yellow glowing light.

Start of speed limit (G 2a/b)

The given number times 10 equals the allowed speed.

G 2a A yellow rectangular sign with a white border and black number.
G 2b A white glowing number.

End of speed limit (G 3)

A white rectangular sign with a black E.

Increment of speed limit (G 4)

A white rectangular sign with a black border and black number.

Protection signal (Schutzsignal, Sh)

Forced stop (Sh 1)

Denotes places where one has to stop if driving on sign. A yellow square with a horizontal stripe.

Protection stop (Sh 2)

Continuing is invalid. A red rectangle with a white border. Equal to Sh 2 on heavy railways.

Emergency stop (Sh 3d)

The train is to stop immediately. A red blinking light or many red lights below. These come up especially in subways.

Ringing (Sh 4)

A white rectangle with a black L.

Border sign (Sh 6)

Denotes the border to which the train can drive. Ein rot-weißes Zeichen oder entsprechende Markierung im Gleisbereich.

This signal isn't placed on the tracks but instead at its physical location.

Stop sign (Sh 7)

Denotes the location where the front of the train should stop. A black rectangle with a white H, a white rectangle with a black H some related markings on the trackbed.

Switch signals (Schaltsignal, St)

Signal contact (St 1)

A signal contact has to be confirmed at the St 1 location. A blue square with a white S.

Weichenkontakt (St 2)

A point control has to be performed at the St 2 location. A blue square with a white W.

Ausschalten (St 3)

The current has to be disabled from signal St 3 onwards. A blue diamond with a black and white border and a split U.

The meaning is comparable to El 1 of heavy railways.

Einschalten erlaubt (St 4)

The current can now be enabled from signal St 4 onwards. A blue diamond with a black and white border and a connected U.

The meaning is comparable to El 2 of heavy railways.

Stromabnehmer abziehen (St 5)

The current collect has to be lowered from signal St 5 onwards. A blue diamond with a black and white border and a horizontal stripe.

The meaning is comparable to El 4 of heavy railways.

Stromabnehmer anlegen (St 6)

The current collect can be risen again from signal St 5 onwards. A blue diamond with a black and white border and a vertical stripe.

The meaning is comparable to El 5 of heavy railways.

Streckentrenner (St 7)

The current collection is to be shortly disabled at signal St 7. A blue square with a white T.

Stop for vehicles (St 8)

Driving through signal St 8 is forbidden for all vehicles with a deployed current collector. A blue diamond with a black and white border with white border and on the inside a white diamond.

The meaning is comparable to El 6 of heavy railways.

Point signals (Weichensignal, W)

W 1 Switch is set to drive straight forward with at most 15 km/h. A white glowing edge which points upwards.
W 2 Switch is set to drive to the right with at most 15 km/h. A white glowing edge which points rightwards.
W 3 Switch is set to drive to the left with at most 15 km/h. A white glowing edge which points leftwards.
W 11 Switch is set to drive straight forward with the permitted speed. A white glowing edge which points upwards and a horizontal bar below.
W 12 Switch is set to drive to the right with the permitted speed. A white glowing edge which points rightwards and a horizontal bar to the left.
W 13 Switch is set to drive to the left with the permitted speed. A white glowing edge which points leftwards and a horizontal bar to the right.
W 14 Switch must not be driven on. A white glowing edge which points downwards and a horizontal bar to the above on a black sign.

Those signs are yellow in Karlsruhe which is why these are tagged with the DE-VBK: instead of DE-BOStrab:.

Monitoring signals for level crossing (Überwachungssignal für Bahnübergänge, Bü)

Level crossing monitoring signals (Bü 0/1)

Bü 0 shows that the level crossing's safety protection are disabled. Stop in front of the level crossing; only continue if traffic allows it. A black and white diagonally striped and retroreflective mast sign.
Bü 1 shows that the level crossing's safety protection are functional. The crossing can be driven through normally. A blinking white light over a black and white diagonally striped and retroreflective mast sign.

Monitoring signal expected (Bü 2)

A monitoring signal is to be expected. A black rectangular sign with on top of each other standing white diamonds. This signal is comparable to Bü 2 of heavy railways.

Special signals (Sondersignal, So)

Start of train protection (So 1)

Transition from driving on sight to driving on train protection. A white square with two dots on top of each other.

Ende einer Strecke mit Zugsicherung (So 2)

Transition from driving on train protection to driving on sight. A white square with two dots on top of each other and a diagonal red stripe which points to the top right.


Auftragsschild (So 4)

If the driving signals stay dark on a level crossing, it tells the driver to stop in front of the level crossing. Driving can be continued if traffic allows it.

Forbid of encounter start (So 5)

Additional signs can be used if the forbid of encounter applies for specific vehicles and directions. A yellow square with a green cross.

Forbid of encounter Finish (So 6)

A yellow square with a black border
