Just found a website that answers a lot of questions that have come up on this forum regarding wiring layouts for DCC. (Truth is, I think I glanced at this site a while ago, then lost it.) It answers my question about twist, jamnest’s “Stranded versus solid wire” thread, questions about safing with auto tail-light bulbs, and lots of layout-related issues that are raised repeatedly on this forum. The link is:

by Allan Gartner. He’s a double-E and bases his recommendations on empirical data, mostly from his own engineering experiments. Of course, it’s not current on decoder technology, but as he says, the physics of layout wiring don’t change. It’s a must-read!
