So I was playing a timetable service in the snow and I realised that the 2nd, 3rd or 4th cars had snow on the windows.
This is a common issue with all trains in tsw2 that may not have snow on them when far away. I wonder if there's a fix for that
But then, to be fair, the cars without the snow just on the windows do look more realistic than the lead car I have noticed this as well, and it would be nice if it was at least uniform across the train. I believe the same also happens when it rains, that the lead car windows are wet (to a somewhat ridiculous extent) and the rest is just dry/normal.
