DPDT Switch Between 2 Main Lines
Tom asks readers:
“Does someone have a wiring diagram for an HO North East Line layout for DCC? And suggestions on gauge of wires to use (from feeders to main lines running to DCC power pack). And, should I use a DPDT switch between the 2 main lines and the power pack? I will be using DCC only. My last question is, should I do soldering or use suitcase connectors? Thanks for any help on this.”

I can answer two of your questions. I don’t know how long your track is, so I am probably suggesting oversize when it comes to wire gauge. The main bus wires (from the DCC Command Station) can be 12 AWG solid wire. It’s easy to find at home centers. I prefer red and black. They should feed the riser wires (track feeders). For the short distance from the bus to the track, 20 AWG or 22 AWG should be sufficient.
I strongly suggest that you place the feeders beneath the layout and follow under your main line track. This will help keep the polarity orientation, especially if your layout is circular. If you use flex track, feed each section with track feeder wires. Track is generally a fairly poor conductor. You can solder the rail joiners and feed every other section. If you are using any of the sectional track, I would solder the rail joiners and feed every third or forth track section (about every meter).
Soldering the track feeder wires to the bus wire will give a very good connection. The use of “suitcase” connectors is much faster and easier. If installed per manufacturer’s instructions, they should be a solid connection. It’s kind of a personal choice.
Good luck and I wish you success.
