Anyone know what arrangements were made between the PRR and EMD for testing F-7's in the early 1950's ? Growing up we used to watch for Bamgor & Aroostook engines assigned to iron ore trains over the Northern Division. I always assumed that they were test engines of EMD on the heavy grades 1.9% pulling the hill out of Ridgway into St. Marys. This section was the ruling grade for the Erie to Emporium run, and many times we kids witnessed the trouble when draw heads parted and it became necessary to double the hill. Maximum number of iron ore hoppers was around 64 cars going east. Most were A,B,B arrangements, although sometimes the Baldwin shark noses had 3 B units or A,B,B,A arrangements on the head end. A pair of I1-sa's always brought up the rear.
