I am color coding wires (so far, red for one rail, black for the other), but haven't labeled anything, as I'm not sure if it's necessary (maximum blocks will be two - one for the RF&P trackage, the other for the C&O trackage). I've also been using a slow, but steady method of avoiding problems with my electrical connections. Marty McGuirk suggested I connect each pair of feeders, then test the track work operation, to ensure I can quickly troubleshoot a problem. So far, other than one sticky Walthers-Shinohara switch, it's been working perfectly (knock on wood). I ran four small trains, two at a time, using the Digitrax Zephyr and a UP5 Throttle. I think my biggest problem right now is lighting. I need to get better/more lighting for both operations and for picture taking.
I hope to do a little more track work this Saturday, with Bob Sprague's assistance. Check back soon for another update.
