Okay here are some small updates I did over the past few weeks.
1. Added animated rollsigns and LCD displays with the help of Andrew. A video of it changing would soon follow later on.
2. Added the black rectangular box within the truck frame.




You can see the animated rollsign in use here. Notice that it's not the generic "A" anymore.
3. Fixed the entirely opaque window/door on the cab end of the car.

4. Added circuit-breaker textures in the cab replacing the monotone colored texture.

5. Adjusted the varying color/darkness of the side textures.
