Changing couplers on an early Atlas HO Alco S2/4

Model Railroader General Discussion (Model Railroader)

I have an early model Atlas HO Alco S2/4 with a Roco drive. The couplers are held in place with pins, not screws. Are these pins a friction fit that can be removed by pulling and twisting?

Yes. You can replace the pins with screws if you tap the holes.
