Tools for this tag

Objects having a tag railway:signal:speed_limit_distant=* are speed limit distant signals. These signals announce a speed limit to the train engineer. Signals are mapped as a node 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 signal. That's why it can have multiple railway:signal:* tags. Combinations of 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_distant:form=sign/light/semaphore – type of signal (sign, light signal, semaphore signal)
  • railway:signal:speed_limit_distant:speed=* – displayable speeds, use none if it is voids a speed limit, use ? if you do not know all of them, off if a light signal may be turned off when other signals at the same pole display pass aspects.

Usage

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