Usage

The tag railway:position=* is used to tag the location of railway objects, along a railway line. The reference system is the so-called distance ribbon; a virtual line along the railway. A ribbon starts at a terminus or junction and ends at such a location as well. The position of an object is then referred to as 'the distance along the ribbon, to the start of the ribbon'. As described, the tag is used to tag the location of railway objects. They come in a wide variety: think of turnouts, signals and bridges for example. At the track, is often displayed by milestones / kilometre signs.
