1: parts of the front bogie will spin with the wheels while it should be staying still 2: wheel shading on the SP, WP, and CNW is not done completely (all black on half of the wheel and silver on the other half) 3: the headlights on all units except the MP are WAAAY too dim, they should be about the brightness of the regular units that came with SMH 4: number lights are always on no matter what the switch in the cab says (all of them) 5: step lights don't look lit even though there is illumination coming from them (always show up as dark) 6: rain does not show up on the windshield on any of the units which is a big immersion breaker (I haven't tested in snow yet but I think its the same case) If these things can be fixed in a later update that would be lovely
