Introduction
🗒️
|
This article uses the unit label meter.
As the reference for this Wiki is British English, the correct label is metre.
Wherever the label meter occurs, it is meant equivalently to metre.

Attributes:
- type: type of length (operational, physical, administrative...) (obligatory;
xs:string ; patterns: other:w{2,}; consider Dev:UsingAny too.)
- Possible values:
- operational: operational or administrative length value
- physical: physical length value,
- validForDirection: indicate the direction for which the length information applies (optional;
xs:string )
- Possible values:
- value: the distance value given in meters (obligatory;
xs:decimal )

*Notice: Elements may have different parent elements. As a consequence they may be used in different contexts. Please, consider this as well as a user of this Wiki as when developing this documentation further. Aspects that are only relevant with respect to one of several parents should be explained exclusively in the documentation of the respective parent element.

Track's usable length
The usable length of station tracks is the part of a track where a train can stop without blocking a neighbouring/parallel station track.
Operational length, normal direction
Operational length, reverse direction
