It is tagged on the edges of a train/tram/subway platform which are parallel to the track and where passengers can enter/exit a vehicle.
Why Do We Need This Tag?
Currently platforms are modelled as unclosed ways or areas (closed ways and multipolygons). If it is an island platform, it is currently tagged with the numbers of all tracks which use this platform. That's why there is a problem both for computer programs and humans which track is on which side. In some cases an island platform has more than two tracks using it (sounds strange if you rarely travel by train).
How to Map
The platform is mapped as an area (typically a multipolygon) with the following tags:
Optional tags of the platform area:
- wheelchair=* (wheelchair accessibility of the platform, doesn't mean that the platform height matches the doors of the train)
Parts of the platform outline which
- are either not parallel to a railway track or
- are not used by passengers to enter/exit a train (e.g. because doors are not opened on that side or there is a fence)
must not be mapped as platform edges.
Such ways must share nodes with the platform outline or be a member of the platform multipolygon.
