Dear all,

Dear Susanne: Please don't lose sight of the forest for the trees... ;-)

- If the train consists of one MU only (most of the trains do so) - what
do you want to reverse there? (Please note that there is no possibility to
describe the orientation of a single vehicle in a <formation>.)
- It is not necessary to specify a formation at all (<formationTT> is
optional). So, for a simple timetable description - may be a passenger
information like HAFAS - there is no need to use create two train parts.
- I can also send you an exempli gratia where a train passes a station
twice without reversing...

But another question we should ask ourselves is: If we specify a
connection with trainPartRef and ocpRef - may it be that the right
interpretation follows from the contents?

Train #24090 stops at Niederhone 14.28 (direction to Eschwege) and again
14.38 (direction to Göttingen). A (hypothetical) bus could arrive at
Niederhone on 14.25 an referring a connection to #24090.
- Do the min/maxConTime attributes help us to specify the right stop?
- Should we (alternatively) refer to <ocpTT>.sequence (the counter)
instead of <ocp>?
- Should we (alternatively) provide optional "directionToOcpRef" and
"directionFromOcpRef" attributes to clarify the situation?

With best regards,
Dirk.
