Objects having a tag railway:signal:speed_limit=* are speed limit signals. Signals are placed on the track. The value should begin with a country-operator-prefix, e.g. DE-ESO: or AT-V2.
Please note that a signal pole/bridge can carry multiple signals. That's why it can have multiple railway:signal:* tags. Combinations of main/combined and speed limit signals or distant speed limit signals and speed limit signals are very common.
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:speed_limit:form=sign/light/semaphore– type of signal (sign, light signal, semaphore signal) - only light and semaphore signals
railway:signal:speed_limit:states=*– displayable signal apsects (e.g. stop, proceed, proceed at low speed, …). The value should begin with a country-operator-prefix, e.g.DE-ESO:orAT-V2. railway:signal:speed_limit:speed=*– displayable speeds, usenoneif it is voids a speed limit, use?if you do not know all of them

Please go to the country-specific signal tagging pages for tagging/mapping railway signals.
