Dear RTM colleagues,
locating elements next to the railway track can be done on the basis of
a LinearCoordinate element and its parameter @lateralOffset. By defining
that negative values shall be handled as lateral distances to the left
(in the direction of NetElement orientation) and positive values vice
versa to the right, the exact location of the element is specified.
Question: How can I model an element situated left or right of the track
without knowing the exact distance? For example: For opening the doors
of the train on the correct side, I just need to know at which side the
platform edge is situated. From my current understanding of the RTM it
is not possible to model this reduced information without using pseudo
values.
Proposal: The information about the side and the lateral distance should
be separated in two parameters (e.g. @lateralSide, @lateralOffset) so
that it is possible to define the lateral side without a specific distance.
Any comments on this issue are highly appreciated...
Best regards
Christian

Dear all,
although there has not been an answer on that topic so far, we need to
find a solution for the problem, because it is essential for railML 3.1
and related "beta 2" version scheduled for end of August [1].
In particular, I already implemented the required RTM related change in
railML 3.1. The latest version of railML 3.1 is available in the railML3
SVN trunk [2]. An overview of all the changes is provided in [3].
In this overview, restructuring the LinearCoordinate by introducing
lateral and vertical offset side is marked as issue number 1.

Dear Airy, dear all,
I'd prefer your alternative solution.
I do not see how the suggested solution solves the issue of "how to provide a side without a concrete offset?", if a value for lateralOffset is still mandatory.

After discussion in the RTM expert group workflow, this is the result:
- Side and positive "offset" (once the side is known) shall be provided
- Semantic clarification: in general, "offset" may be positive or negative, we prefer not to use it in RTM because it may induce misunderstandings; instead:
- Attributes @lateralSide and @lateralDistance are introduced, replacing the proposed @lateralOffset, where @lateralDistance is essentially positive. Rules are: both attributes are optional; if @lateralDistance is provided, it shall be positive or zero, and @lateralSide must also be provided.
- Attributes @verticalSide (proposed values: 'up', 'down') and @verticalDistance also to be adopted, as suggested in the workflow, for reasons of consistency.

Dear all,
the following solution / clarification by RTM Expert Group has been
considered in latest railML version 3.1 beta (2) implementation. You may
download the related schema files etc. via railML's SVN repository in [1].
