Rich Yoder 44 tonner with electro-couplers. An early ERR TMCC upgrade. Couplers are part of Atlas articulated couplers that were torn apart and modified to fit. I also used an Atlas coupler cover part.
Original three rail couplers.
Used the same coupler mounts. Note the coupler shank modification and the additional opening in the pilot.
ERR upgrade and sound. A lot of luck, with this upgrade.
