Bio-mas hopper wagons

[njee20]

I'm always struck when watching videos that trains appear much longer. I think it's because they appear in frame one wagon at a time, whereas when viewing in person you can see the whole thing.

I tend to think that if freights are longer than passenger trains it looks about right. That works both ways; I ran a 12-car 350, and it actually looked a bit daft, 8 looks much better!

Long winded way of saying that I agree with Ben; 13-15 is a good length for a freight IMO unless you have tonnes of space.
