Alco road switchers like the RS-3 shown above were a common sight on the cape. I saw a lot of them on the Woods Hole branch in the 50's and early 60's. In fact for loco hauled trains they were the main motive power on the Woods Hole branch. Throughout the 50's they were normally painted in the reverse of the colors above--orange body and black cab. Late in the 50's I started seeing some with the above color scheme. After the Woods Hole turntable was removed around 1951, there was no turning facility on the branch, so road switchers were the norm. For passenger runs they normally shuttled back and forth between W.H. & Buzzards Bay where cars were added onto or removed from Hyannis trains.
