[1.1.39] Wall textures clipping on top of diagonal trains

[GuillaumePoi]

Hey,

When you have a train positionned in dagonal and walls placed as near as possible to the rails, the following visual bug happens

I expect the wall texture to be under the train.

To reproduce the bug, you need to drive a train in diagonal besides concrete walls, some corner of the walls will clip dear the start or end of the train. The bug also happens on trailers.

I uploaded a test map,gif of the bug happening and log files.

Have a nice day
