Conclusion of the discussion during the timetable-developer meeting on 22.01.2016 in Berlin:
Dear railML users.
We were looking for a way to reference a connection to an external train (bus, ship, etc.) that is not listed as train within the same railML file.
The idea is to have a sub element <externalReferences> with a choice of different elements to reference an external train via:
* unique tafTapTsiTrainID
* trainNumber (and maybe the related IM)
* lineNumber, e.g. a connection to the trains of the line 'S6'
* information, e.g. 'Connection to Berlin via Wolfsburg'
Do you have any remarks on this approach?
Kind regards,
Joachim Rubröder
The XSD would look like this:
