There is a typo, I think you wanted to cite the following URL:

http://trac.assembla.com/railML/ticket/126

Why not to implement the 'trainPartRef' instead of 'trainRef'? It is
much more specific as Andreas already mentioned.

Currently no ocpTT may be referred because of the missing "id" attribute
in the <ocpTT> element.

Wouldn't it be sufficient to refer to a certain 'trainPart' and an
'ocp'? A 'trainPart' may traverse a certain 'ocp' only once. If it
changes its direction this should be defined as a distinct 'trainPart'.

We currently speak about "heavy rails" not about tram systems where
turning loops are common. But anyway the 'trainPart' changes running
their.

The reference to a certain platform stays to be resolved with the above
mentioned ticket. But this is a more general topic: how to refer to a
certain platform inside the timetable?

Currently the string-typed attribute "trackInfo" in the <ocpTT> element
is used for this, but since railML 2.2 the infrastructure enables
defining platformEdges for tracks that may be referred from the
timetable.

Kind regards...
Susanne
