Objects having a tag railway:signal:main=* are main signals. Signals are placed on the track. The value should begin with a country-operator-prefix, e.g. DE-ESO: or AT-V2.

Additional keys

• mandatory: railway:signal:direction=forward/backward/both – direction which the signal is valid for
• railway:signal:position=left/right/overhead/bridge – position relative to the track (direction of OSM way) where the signal is located

There are a lot of additional tags which describe the signal in higher level of detail because every country (or even railway company) has its own signalling system.

• mandatory: railway:signal:main:form=sign/light/semaphore – type of signal (sign, light signal, semaphore signal)
• only light and semaphore signals railway:signal:main:states=* – displayable signal aspects (e.g. stop, proceed, proceed at low speed, …). The value should begin with a country-operator-prefix, e.g. DE-ESO: or AT-V2.
• railway:signal:main:height=* – the height design of the signal (dwarf / normal)
• railway:signal:main:substitute_signal=* – signal which is mounted at the main signal and used if the signal does not work
• railway:signal:main:function=entry/exit/intermediate/block – function which the signal serves (e.g. entry signal of a station)
