This is really expensive to put a PS-2 board in just for smoke, but your railroad. The PS-2 or 3 O diesel boards are the same basic size and big regardless of model engine. There are no small boards. Yes the S gauge board is smaller but a one off. I guess if your just after smoke an lights in a dummy you could go HO board, but your going to have to go with AC version. This is not easy to do as separate parts not easy to get.
The tether is easy. Lights, coupler, smoke. PS-3 does it with the early slave model. Otherwise your buying a diesel kit, plus a smoke unit.
Just by a newer smoking switcher. Cheaper to paint the shell then do the modes your considering. G
