John, before DCS was released I had that problem while learning the system. I have my big yard with 23 tracks and my turntable with 40 tracks. On my big yard each track was controlled with toggle switches. On the 40 tracks at the turntable, control was done with rotary switches. I ended up adding a common buss wire to all track grounds. I immediately got a 10 signal. I have that same 10 signal today. People have had success with lighted bumpers. As we know, yard tracks and sidings can be tricky. I know Barry has lighted bumpers and has success with them. Being a toy train guy, I love the look of the postwar red lighted bumper. I may put them on yet and wire the center rail contact from another power source. I was thinking a rail cut in front of the bumper and wire the end of the track with wires soldered to them. The look of 23 lighted bumpers will please this toy train guy.
