Thant was my first guess Chrizzly but after seeing this close up picture of the tiny wheels with no evidence of friction tires I discarded that idea....the mystery is exciting.

Here is another interesting tidbit I just noticed on just the see inside cars, the two with close up pictures both have what looks to be the heavy 'Eye Hooks' commonly only seen in use by the motorized tender driven trains. These use the hole method where the hook can swivel side to side as opposed to the normal 'Pegged' hooks that can only go up and down. Hmmm...another mystery.
