Dear Peter,
Peter Vancsa wrote on Fri, 26 June 2020 11:28Hi everyone,
My name is Peter Vancsa, I am a software-engineer with Siemens in Braunschweig and working on importing a railML-3.1 file into an integrated engineering solution.
Welcome to the railML forum!

So, here are a few questions regarding the 'Simple Example' file:
In the example file all bufferStops that are placed at the beginning of a netElement (so pos=0.0 or basically intrinsicCoordinate=0) have the appicationDirection set to "reverse". I was expecting this to be the same for all switchesIS as well, however switchIS "swi03" (69W04) is placed with applicationDirection="normal". Is this a mistake or why is that so?
The switch 69W04 is located on NetElement "ne_b02". And it "functions" as switch (with choice of way) for trains that pass this NetElement in reverse direction. Therefore, you are right: applicationDirection of the switch element need to be corrected from "normal" to "reverse". Thank you!

Application direction "normal" corresponds to "up" and "reverse" corresponds to "down". Does "normal" mean the direction of the edge (from intinsicCoordinate 0 to 1)?
Yes, "normal" refers to the orientation 0 to 1 and "reverse" refers to the orientation 1 to 0 from a intrinsicCoordinate point of view.

And lastly, the netElement ne_b05 has a length="200", and two intrinsicCoordinates "0" and "1", but no linearCoordinate on any of the two intrinsicCoordinates. Was this forgotten here? I expected an edge to be always defined between two points, either 2 linearCoordinates so that the difference on measure corresponds to the length, or 1 linearCoordinate and the length (which allows the computation of the other one).
The NetElement "ne_b05" is not linked with the line kilometer positioning system described by the linearPositioningSystem "lps01". However, the provided attribute @length="200" gives an information about the physical dimension of this NetElement. Consequently, locations on this NetElement "ne_b05" can only be described with intrinsic coordinates in the range of 0..1.
Best regards
