Robert, the snow can be deep enough on the rails to derail a hyrailer (truck with extendable flanged wheels). That is why they have the units (one on either end for ease of movement in both directions) and the caboose in the middle.

Why TWO engines?
Could they not use a fuel efficient, comfortable, quiet, air conditioned SUV-type vehicle with extendable flanged wheels?
