This was one of 60 (MP #'s 9000-9059) late production C36-7's ordered by the MP to UP specifications. The last ten of the order featured frames with anti-climbers originally destined for NdeM units but diverted because of that road's financial problems. These units also had a larger than usual (4500 gallon) fuel tank, forcing the air reservoir tanks into the radiator compartment. It rode on rebuilt truck bolsters from MP U30C trade-in's, and was rated at 3750 horsepower. Beginning in February 1988, all of MP's 9000 series C36-7's were upgraded at North Little Rock. The upgrade included rebuilt trucks, rebuilt engines, new radiators, and UP lettering.
