Dear all,
following our 35th railML Conference in Linz last week, I want to pick
up the topic of the switch reference point again and summarize the
current state of the discussion:
1) Depending on the use case different points of the switch are of interest.
2) For SCTP (schematic track plan) the WM (switch center, crossing point
of tangents) seem to be the interesting one.
3) Use cases that have higher requirements on the lengths of the tracks
the WA (switch begin) seems to be the best choice.
4) The WA (switch begin) is not clearly defined: some people locate it
at the (virtual) begin of the radius of the branching track while others
locate it at the begin of the switch tongues.
5) It would be good if a switch can be located via a <spotLocation> with
any of the forementioned points and requirements.
And now my questions to you, dear community:
a) Do you consider point 5) as essential for railML 3.x?
b) Which point will you choose if you locate the switch via a
<spotLocation>?
Thank you very much and best regards
Christian
