Last night my father & I got the outer loop of track set in place & the basic wiring finished. Able to position the WiFi unit on the shelf ouside, with the TIU & AIU to be eventually wall-mounted in the closet/bathroom. That should leave room for the LEGACY unit on the shelf. Left wires long for now; they can be trimmed once final positions for everything are determined.
Dad screwed in the eye lag screws - hard to find & larger than I would have preferred, but they should work fine. Will run wire (or perhaps 20# test fishing line) for a safety barrier should a derailment occur.
The initial electrical test was a success! MTH DCS Wifi worked as expected. After an initial test lap w/my Cleveland Union Terminal GP-9 we performed a clearance test with the CP Holiday Train. One of the eye lag screws needed to be repositioned at an angle for clearance, but that easily fixed the problem. May need to reposition a few more screws when I run 21" passenger cars, but so far so good. Still have yet to finish fitting the inner track, which will eventually be the main line, as well as wire the switches & some buildings.
I will keep you posted on my progress, & I hope to have some more pics & maybe a video or two up soon! Take care & Merry Christmas to all!
