I superimpose the wheels sprite on top of the ingame screenshot.

Problem: Graphically, it shows that the "Flange" of the wheel is on top of the rail , instead of the "Tread".
Not a gameplay problem, and it is pixel-size graphical 'glitch'.
Visible with non-locomotive wagons .

Real life comparison:

Thanks for the report however we have no plans to re-render every train sprite.

Understood. if there is any that can be fixed, it will be the train wheel sprite only and that one particular vector, but of course, this is too minor to work on.
