This just looks dreadful. Really though, if there is no way to overcome the off-set and empty spaces, frankly, the reversal should be handled in some other manner that doesn't affect the graphics. Just looks preposterous with huge gaps and some wagons overlapping the others and such. Generally I try to use tank engines to avoid some of the most silly gaps but with brake vans and goods wagons it gets really goofy.
I believe there were issues on spacing on vehicles, if that is of any help.
This has been known for some time, but I have never worked out a way to solve it. If anyone who knows anything about the graphics code (which I have barely touched) has any ideas, I should be very grateful.
