Modelling switch crossings in infrastructure
Description
It was suggested to provide a solution for modelling a double switch crossing as composition of two ordinary switches. However, it shall be also possible, to model a double switch crossing as a single element. Same applies for the single switch crossing.
Background
In infrastructure data base of BaneNor double switch crossings are included as component elements. ETCS use case working group suggested to transfer this composition also into the railML schema.

Proposed solution in railML 3.2
Introduce new switch @type enumeration values:
-
"switchCrossingPart"to be used for ordinary switches that are actually part of a double switch crossing or simple switch crossing
Add new attribute @belongsToParent in element <switchIS> to reference the aggregated switch from its parts/partitions.
