I have the center rail hooked up to A and the outside rail hooked up to U (using a lighted lock-on). I also hooked up the switches to the constant voltage, post D, using the constant voltage plugs. There are 4 switches. When I plug the transformer in the switch lanterns and switch controllers all light up before I apply power to the track. When I run the train, everything works fine. Until I use the whistle. Then the bell goes off instead of the horn. Tried a couple different engines and same story. I then switched the A and U hookups and the horn goes off instead, like I want it to. The only difference is lights don't go on for the switch lanterns and switch controllers until I apply power to the track.My question is will this setup work and not cause any damage to the switches, the locos, or the transformer? I think when I hook up the switches to D an the outside rail to U then the switches use the outside rail as the common. Just not sure.
