I secured this print from a fellow in Harlan, KY some 45 years ago. It was torn in a couple of places, but with some work, I've managed to clean it up with Photoshop. This is along the CNO&TP, probably during WWII (when movements of gasoline and other fuels by train--to avoid German U-boats just off US shores in the Atlantic). This is an Ms-4 Mike--the principle main line freight hauler on the Rat Hole. Either this train is slogging it out on a heavy grade, or rolling along at a pretty good clip. The semaphore is at a 45 degree "approach" position, so if the train is moving fast, there is probably a train ahead two blocks away. If it's moving slowly, the block was clear (blade straight up), but has already fallen 45 degrees with the engine barely past. What do you think? (Photographer Unknown)
