I don't quite like the c00 numbering of this.
I would better like c01, or using an u.....dat number.
Just sticking to 2865 here is IMHO somewhat unnecessary.

I think we should not have this filename 2865c00 at all.
Just renumber it to 74746.dat, and we're fine.

This is an assembly of plastic moulding 2865 and two formed metal pieces. The convention for ????cNN files is that they use the base number of the most obvious component moulding. Yes this could be 2865c01 and bump up the other four, but it DEFINITELY should be 2865c??.

I'm sorry to come up with this this late, but I just discovered
that this file has a different vertical origin than the
currently official 4.5V and 12V files.
(Both the origin choice there and here of course make sense in their way.)
However, I would like to achieve that this file, and its 4.5V and 12V
counterparts can be freely interchanged, without having to each time
correct the vertical positioning.
We have a chance here to do that now, because this file can have
that origin, and the MOVED-TO pointing here can compensate for that
to achieve downwards-compatibility.

I think we should apply that change. Do you as well? Chris?

(that vertical origin change of course should also be applied to the left and right point parts.)

unfortunatley, my vertical origin change suggested above is impossible.
I suggested it to make the 9v train track have the same origins
everywhere as the 12v and 4.5v tracks.
This would allow, e.g. in train track layout software, to simply
swap between these.
this would be possible now, I thought, because currently all 9v
parts are on the PT, and an origin change is possible for all of them.

BUT 1 part is not: the crossing 32087.dat

I am pondering this through an through currently,
and sometimes I think we should 32087.dat MOVE-TO 32087a.dat
and give it the vertical origin change there.
Would we do that, then we could adjust also the other 9v train
parts currently on the PT, and finally would achieve
that train track layout software could freely interchange
4.5v, 12v and 9v train track parts without taking care
of each time compensating the different vertical origin.

what do you think here?
each time I come back here I think we should maybe DO that vertical origin unification...

Comments:
A train track application needs to be aware of all separate items and their numbers. So the additional work for the correct origin that all fits together needs to be done by that application, not by our library.

Reviewer: technog

Comments:
I agree with mikeheide, this library is not responsible origin in applications.
I also agree with what steffen is suggesting that we should keep similar parts consistent with one another.
However, I disagree with steffen and the desire to shift the 9v track system to do this.
The 9v track system has the origin logically placed on the top of the plate as all other parts.
Whereas the 12v and 4.5v have track systems have their origin at the top of the rail which feels wrong to me.
