wiring a model train layout, Bus line, feeder wires, for DCC. for this video we take a look at adding a bus wire to your layout. Bus wire is a larger gauge of wire, 14 or 12 gauge run under your main line. following your track around the layout. the main bus line is a wire that will feed your track is multiple spots. by adding track feeders. track feeders are smaller wires, 18 or 22 gauge. that come off of your main bus line and you solder them to your track. solder them to the UNDERSIDE, or the OUTSIDE of the rails.
when doing your feeder wires keep in mind the black wire and the white wire have to stay on the same side of the tracks for the full length of your main track line. use a box car with a door that can open and run it on your tracks. what ever rail is on the side of the box car with the open door. then that wire is white. closed door then the wire is black.
feeder wires have been a discussion for a long time. some people drop them every 2 feet of main line. others drop them 4 feet, 6 feet, 8 feet. I myself drop feeder wires every 6 feet. and before and after every turn out, (switch).
