Steve, I have a question. I'm building a small portable conventional layout with one loop of track and one siding. It is broken into 4 blocks so that you can switch from the running engine to one parked on the siding, so basically I'll only have one train running at a time. Would one circuit breaker be enough protection for all of the track or should I put one on each block? Oh, this is being built on a hollow core door, so it's a really small layout.
Thanks!
