PRR FF2

From Wikipedia, the free encyclopedia

The Pennsylvania Railroad's class FF2 electric locomotives comprised eight boxcab units purchased from the Great Northern Railway in 1956 following the GN's dismantling of its Cascade Tunnel electrification. Their GN classifications were Y1 and Y1a. One unit was dismantled for spares, and the remaining seven were overhauled and converted to PRR standards and then placed into service, being assigned #1–#7 on the PRR.

They were of 2-6-6-2 wheel arrangement in the Whyte notation, or 1-C+C-1 in the American Association of Railroads scheme. They used motor-generator sets to rectify the AC line voltage into DC current for their traction motors.
