I saw this today while out train watching. It is pulling gondolas full of ties. [:D]

Definitely uses traction tires. Don’t think I’ve ever seen a truck that big on tracks before.

Who says real trains don’t use traction tires?

And when it decides to jump the tracks, you’ll find it driving down the highway with a big knuckle coupler on it’s bumper, which leads me to believe that I may have seen this thing once before, but not in this context.[:D]
