Hello Andreas,
as far as I can remember, on 19th March 2012 we thought about having an
example and may be a recommendation where and how you wanted this new
attribute to be included.
- Can you write an official source of "UIC train transport id"?
- Is it a property of an operational train, a commercial train or of a
train part? This means: Will it be used with timetable to be 'published'
in any kind (which would bring us to commercial trains) or with trains of
an Infrastructure Company (which may bring us to operational trains)
and/or can it change during a run of a train (which would bring us to
train parts but I think this is improbable).
- How does it work with these typical trains having the same train number
(DB: "Ergänzungsfahrpläne")? Or: Is it sure that each train has a
different "UIC train transport id" or may it be that there are two trains
with the same "UIC train transport id"?
Since you are the only one who needs it so far and who knows the origins,
I think you are the only one who knows this.
> We have indeed customers that use this id.
Yes, but that does not necessarily bring it into RailML. There are many
information used by customers but not in RailML. To get it into RailML,
there should be a demand on _exchanging_ these information, which normally
means that at least two programmes need it.
"UIC train transport id" sounds as general as if we could implement it
ahead in advance. But we have to make a good decision where and how
because if we make a mistake there, it is not easily to correct in future.
Best regards,
Dirk.
