Trains are great, but what if they could do even more?
It's awesome. Does this support wagon too or planned to be?
Do you mean the tank wagon? I would second that.
There's a "Color Picker - Wagon" that claims (haven't tried it, but would be the first lying mod) that you can change the color of wagons. I'd love that. Actually, I'd prefer neutral (non-red :D) locomotives and auto(!) colored wagons.
