I was talking with someone who’d rather remain anonymous regarding AC and DC power on train layouts. When using AC power, a common trick to reduce the amount of wire you need is to run a power wire to each loop of track, and feed that loop of track from a dedicated loop of wire. Then you can run a second loop that each of your loops of track use as a common ground. His question was, if you wired your layout like this, would it be possible to switch to DC power?
The answer is yes, with a possible caveat.
