This MP15AC started life wearing scarlet and gray. Southern Pacific was one of several railroads to buy the MP15AC for switching. The MP15AC largely replaced the older MP15DC. Do not let the name mislead you...both models had DC traction motors (as AC traction motor technology was not really developed until the 1990s). The MP15AC, however, used an AC alternator to generate electricity that was then converted to DC for the traction motors.

UP sent UPY 1480 to Grand Junction, CO, for storage along with several other units in May 2015. Business slow down had UP purging their fleet of older units.
