I measured another model at various points and remodeled the train from the ground up. Model is meant to be printer friendly with no supports required.

Wheels were removed from the original, though I did model them in OnShape, I wasn't able to think of an efficient way to have them not require supports anywhere. That said, in my version of the game the tokens do not have the wheels so this is more true to my version of the game.

I mainly wanted to print these as the in-box tokens have a very annoying sound when they hit the table. When I found the models appeared to be 3d scanned, I decided I would recreate the model in onshape.

No raft or brim were needed on my XL and CoreOne. 

Printed at 0.2mm layer heights. I did print with a HF nozzle but I imagine a non-HF should end up looking about the same.
