Hi,
My name is Sara and I an a researcher working with timetable planning. I have just started looking into railML and I have a question regarding "timing links", namely - do they exist in railML?
Part of my research is using optimization to construct timetables, and the model I use relies on minimum run-times for each link that depend on whether the train stops at any (or both! of the ends of the link. In our vocabulary, each train part belongs to a "timing load" class that is specified by important aspects for estimating the speed (e.g. train type, locomotives, weight, max allowed speed). For each track and each timing load, four minimum running times are specified, one for each of the stop patterns: "Stop" - "Stop", "Full Speed" - "Stop", "Stop" - "Full speed" and "Full speed" - "Full speed". Are these timing loads and timing links defined in railML?
Happy to be here!
Best Regards,
Sara

Hello Sara,
I once had a similar problem: I needed to exchange run times for different kind of train categories. The stop pattern was not part of my considerations.
I decided to add elements "runTime" in a new namespace with attributes "duration" and "categoryRef" below the element "track" and add references to these tracks in the element "sectionTT".
For your problem a similar approach might make sense where you could add an attribute "stopPattern".
Besides that you can set the "minimalTime" in the "runTimes" element of "sectionTT", but you would have to do that for each operation control point of the train's run.
Kind regards
