Running on the former Buffalo & Southwestern division of the Erie, which ran from Buffalo to Jamestown, New York & Lake Erie FPA-2u #6758 passes under the abandoned right of way of the Erie's line from Dunkirk to Salamanca. Built as an FPA-2, the #6768 was upgraded to FPA-4 specifications by MLW for CN, hence the FPA-2u model name. It is the last surviving FPA-2, making it a pretty rare machine.
