See you asset library proves that you can make trains that look good, but aren't 40mb big. Great work

The visual stuff has no effect on the actual cargo the train can carry, so this thing can carry everything from logs to cows to commercial goods. So yeah, coal is purely visible, I've set it to show up for several of the cargo types so the coal load in the train reasonably reflects the actual cargo load percentage that you can see when you click the train. To do this it has several submeshes, one for each cargo type I wanted the coal to show for with the coal mesh, and a main wagon mesh.

I’m trying to understand how the new cargo wagon system works (just found out there is still only one vanilla wagon with just different submeshes, so my knowledge is really limited), so i was wondering, how does this train work? Is the coal purely visual and can the wagons also contain, say, logs? Or does this train only move ore? (And if so, what happens to the other types of cargo, and what would happen if i told a station to only spawn this train using service vehicle selector?)

Who doesnt like the trainspaghetti in his/her city? But right you are... ;)

Well, long trains tend to block intersections so I try to keep most of my assets around the default train length. You can change it in the asset editor or use Random Train Trailers to overwrite the trailer count.

nice work man, thanks for that!
but the train feels a bit short with that monster of a locomotive O.O

Nice colors on that train :p
