I want to run two trains off of a KW 190 watt transformer. I believe I have correctly wired a double signal bridge to two 153C contactors. I am not sure how to connect the two wires that go to the transformer. I also am confused on where to place the insulating pins. Do I also use a second standard contactor to power the second train? Any help greatly appreciated.
longwords,
This sounds like Lionel three-rail wiring and accessories. You will probably have better luck getting an answer on the Classic Toy Trains forum. Most everyone on the Model Railroader forum is two-rail DC. You need three-rail AC experience.
