Hello,
prior to our meeting next monday, let me toss some litte ideas around.
Firstly, there is a wish for a "stop post" element/attribute in the
infrastructure branch:
A platform at a station may have more than one stop posts for
different kinds of trains, mostly depending on its length, sometimes
depending on other properties of the rollingstock, e.g. axle count,
verbal "rollingstock kind" or wagon count.
It should be possible to refer to such "stop posts" from within a
trainParts ocpTT to mark a special stop position.
That's quite a bit confusing. Different train parts can't stop at the
same "stop post" - they run one behind the other. Certainly it marks the
stop position of the head of a "whole train" (railML semantic:
"operational train"). But the "train" doesn't provide stops (railML
semantic: "ocpTT").
I would prefer creating an element for enabling coordinates and
above mentioned stopping constraints.
Where to put the element in the infrastructure branch? Could it be
linked to a "crossSection" (for easier referencing from within the
timetable branch)?
Could we reuse the "ocpRef" attribute in "ocpTT" for this more
detailed ocp stop position?
I am very interested in any hints, questions and comments.
Maybe seeing you soon in Karlsruhe...
Susanne
