Thanks. I was hoping not to have to disconnect, but I will. Crawling around on the floor at my age is undignified at the best of times. I don't understand the concept of a break in the bus bar, how does the power continue? Please explain. Mine is a horseshoe shape already. And I have linked the dcc controller to one end - is this OK?

I got the Loco to run on one piece of track, so I know it,s not this. The piece of track was in a siding, and not connected to the main circuit.

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?
