The service tag is used to provide additional information about a highway, railway or waterway.

Usage in shop=car

Main article: Tag:shop%3Dcar


The service tag can be used to provide more information for a highway=service road. Add a oneway=yes/no tag if appropriate.


service=* is used to describe minor tracks, which still are tagged with railway=*, at railway stations and yards more detailed.

Tracks running straightforward through a station without turning right or left at switches are tagged usage=main/branch/industrial/military/test without service=*. This is useful for map renderers (e.g. OSM Carto) which can hide minor tracks at lower zoom levels and for railway routing engines which can prefer the fastest way through a station (turning left/right at a switch requires the engineman to reduce the speed).


See also landuse=railway about mapping not accessible railway yard areas.


This tag is used for the tracks at yard stations which are operated by the railway company itself (in difference to spur tracks).

The difference between a yard and a siding track is the absense of main signals at yard tracks while siding tracks have main signals.

Some yards have track numbers you can see from outside the yard area. They are tagged using railway:track_ref=*. Sometimes this numbers only can be derived from the signal numbers.

Siding Track

This tag is used for tracks which run parallel to the main track and are connected to it. These tracks are used by slower trains to be overtaken or to let passengers enter/leave the train if the main tracks do not have platforms. These tracks might be hard to differ from the main tracks in some cases.


Spur Track

This tag is used for short tracks connecting a factory or power plant to the railway network.


Crossover Track

This tag is used for only few metres long tracks connecting to tracks of different directions of traffic. To be found only on double or more tracked railways. Often found in stations and at (crossover) junctions.



The service tag can be used to distinguish open man-made waterways (waterway=canal) between transportation, water power, or irrigation.
