After some research I came to the same conclusion as Johan: this mod 'breaks' vanilla boxcars available from 1950. It somehow alters the texture of the vanilla boxcar, making them hideous.

Lexy, wanneer ik deze mod actief heb in een spel geven de vanilla Hbis wagens textureproblemen. Ervaar jij dit ook?

If I can suggest a truck version of these wagons. The style is very striking and would be cool to use for my mail routes

@andrew, CookieBoss. rendering issue has been fixed

also ive been waiting a long time for a post wagon well done

The wagons are amazing but they disappear on distance.
