Stopping places and platform edges

Description

In railML 3.1, a <stoppingPlace> can be linked with only one <platformEdge> using attribute <stoppingPlace>@platformEdgeRef.

In the railML ITMS use case working group it has been concluded that a stopping place can be linked with more than one platform edge. Therefore, the model shall be adapted for railML 3.2.

Background

A stopping place marks the position on the track where the train shall stop.

A platform edge is the interface between passenger train and station.

Proposed solution railML 3.2

The existing attribute <stoppingPlace>@platformEdgeRef shall be marked DEPRECATED.

A new repeatable child element <allowsUsageOfPlatformEdge> shall be introduced to reference a <platformEdge> element.
