Dear RTM colleagues,
railML 3.1 uses RTM for describing the railway network topology
(NetElement, NetRelation) as well as for defining different positioning
systems (GeometricPositioningSystem, LinearPositioningSystem).
The element LinearPositioningSystem provides essential parameters to
specify a mileage chain that is the classic linear positioning system
along railway lines. In particular, the child element LinearAnchorPoint
is used to model gaps and overlaps within the mileage system. However,
when experimenting with real world examples, it has been discovered that
there is missing a parameter or element to define a change in the
mileage orientation - for example from increasing mileage to decreasing
mileage.
So, the resulting question to be answered:
Is the existing model of LinearPositioningSystem complete w.r.t.
modelling all (nasty) aspects of mileage, and in particular for changing
of mileage orientation? It will be great if you can provide an example
showing how to deal with this situation.
Thank you very much and best regards
Christian
