Geez, you will finish this gargantuan layout in like no time, and I can't even get my basement finished to start a layout (only been about 20 years...) *lol*. I am amazed at the craftmanship I see, the wiring and woodwork is first rate, to say the least...
Out of curiousity, how did you make out with the issues with the TMCC signal strength, was it a ground plane issue?
