a good design allows for a simple adaptation to make a dual purpose able item, like a truck/trailer towing, or a sofa sleeper, or a draftsmans table, or this tractor / train engine

in the above, visible on the far side rear rim, they bolted on a flange

and that made this tractor able to roll on rails as the front rims were made with flanges and the right distance apart

if the tractor looks a little familiar, maybe you're remembering the trench crosser
