Yeah exactly that, they all have the same sort of wheel base, that and almost all of them only have x4 wheels, wouldn't it be great if they had more? More driven wheels and more support wheels, one of my pet hates is the fake 'moulded' plastic wheels, I can understand why they do it - the radius of the curve, But because they all have the same sort of wheelbase I think you End up restricting the body you can put on the chassis. Look at the dd51, the proper loco is really long with 18wheels, we end up with a stubby wide model (which is fine) but it's not overly accurate,

Well, what if there was 4-wheel drive? It could fit inside the shell, but it may be a few millimeters longer. That would be a mind blowing feature!
