Four B&O SD35s shove hard on the rear of an eastbound manifest at Amblersburg, WV on Sept. 13, 1975. Track work on the eastbound track has the train climbing Cranberry Grade on the westbound. In my many trips to the West End, this was one of the few that I caught a helper set with four blue units. By the time I got there, it was almost always mixed blue B&O and Chessie.
