I have just changed from a simple analogue layout (circular) to dcc. In order to do this, I fitted a bus bar with dropper wires. I'm new to all this and can't get the dcc Loco to run. I have linked the controller to the end of the bus bar, and also by separate wiring to the bus bar. I've run an electrical tester over the rails and these show as being live.
Can anyone offer any practical advice, otherwise I'm returning to analogue?
