Mark and Sheldon spend a frigid early morning waiting at Cochrane Shops' fuel stand while Shops' workers round up a 2nd APU that will be sent out from the shops and coupled to their power (GP38-2's 1806 and 1800). Once the 2nd APU is coupled up, the boys will lift the remainder of February 7th's Polar Bear Express coach consist which already has the first APU coupled to it.
