Dear Christian,
dear all,

to answer your questions - yes, we will need extensions in IS.

1) We shall have a new element "tunnelGateIS" in functionalInfrstructure, which
shall provide the position of this gate and the relation to the <overcrossing>
(tunnel).
For small tunnels the exact position might be neglectable and just using the
tunnel position. However, for longer tunnels the gates will be controlled
separately and thus we need to know on which end of the tunnel (or even in its
middle) the gate is located.
In the IL scheme the element will be named "tunnelGateIL".

2) The attribute @constructionType may be extended for <undercrossing> (bascule
bridge) to have the information in IS already.


Best regards,
Joerg v. Lingen - Interlocking Coordinator

[railML3] Linking between platform edges and stopping places [message #2644] Wed, 20 January 2021 14:58

Dear railML community,

in the railML use case working group "ITMS" [1] the link between a stopping place and a platform edge has been discussed. The conclusion of the discussion was that a stopping place can be linked with more than one platform edge (e.g. when having platform edges on both sides of the track).

So, it has been requested to adapt railML 3 data model: The existing attribute <stoppingPlace>@platformEdgeRef shall be replaced by a (repeatable) child element <stoppingPlace><allowsUsageOfPlatformEdge> that provides a link to a <platformEdge> element.

I summarized the approach in Trac ticket #454 [2] and kindly ask for your feedback: what do you think about this idea? Do you have remarks or requirements for adapting this solution proposal? Any kind of feedback is highly appreciated...

Thank you very much and best regards
