Hello Susanne,

although any railML user didn't reply to your questions, it's obvious
that we need a stop post element for specifying the positions on the
platforms where the train may stop.

These details need to be discussed within the timetable schema forum.

The stop post itself is a physical element, which is a sign right next
to the track. Therefore I would not use the crossSection element for
specifying stop posts. Instead I would put the stop post element inside
the ocsElements container. The even more difficult question is how the
stop post can be referenced with a certain platform (=serviceSection).
Like with an ocpRef, the sign post may directly refer to the ID of a
serviceSection via an attribute serviceSectionRef. What do you think?

Kind regards
