Dear all,

Many thanks for both of you for this long thread and all the clarification
which will indeed be very helpful for every outsider.

I appreciate to force the splitting in trainParts whenever the formation
changes, also for orientation changes.

A forced splitting of trainParts whenever an ocpTT would occur several
times would be consequent. This would also solve the problem of
referencing the correct ocpTT within a trainPart
( http://www.railml.org/forum/ro/?group=2&offset=0&thr ead=72&id=247).

I would like to keep the 'trainReverse' attribute, for this purpose which
was also mentioned by T. Kauer (SBB) at the railML meeting. With the
forced splitting of trainParts, the 'trainReverse' would mainly occur at
the first ocpTT of a trainPart if you have any formations referenced. It
should therefore no longer be seen as automatically reversing the
formation. For a simple timetable information system (without dealing with
formations) it could still be used within a long trainPart to indicate the
symbol <->.

Best regards,
Joachim
