Here are some issues I’ve found with the Kassel - Wurzburg 146 and Dostos (both) PZB and Sifa don’t acknowledge when you press B (146) PIS screen is very dull (Both) If you set the destination to a destination that you aren’t going to, it will reset to the destination you are going to (Dostos) side PIS screen is off center (Dostos) passenger lights are dull and missing some light (146) PIS board won’t set to blank when you try to, it just keeps going to “Nicht Einsteigen” (Dostos) top floor glass doors inside the coaches don’t open and you can just phase through (Dostos) door closing chime doesn’t work (except for cab car) (Dostos) the front PIS board doesn’t work if you set the destination from there (Dostos) sometimes you can’t pick any destinations for the PIS screen (Dostos) inside PIS screen doesn’t work (except for cab car, though it can still break in it) (Dostos) inside PIS screen is broken (the actual time is 10:13) That’s all I found, let me know if you guys found any more
The 146 and all other red trains, except for freight ones, are only there as ai. You aren't supposed to be able to drive them or really do much with them.
