BNSF typically runs loaded oil train on the Moffat with three units on the point and three on the end. Union Pacific has opted for three mid-train helper about two thirds of the way through the train. The first DPU, UP 7000, was originally GECX 4000 and was a warranty protection unit, built in 1997. It was subsequently bought by UP and added to the roster as UP 7000.
