I have been in the hobby/trains exactly 1 year and the layout is 10 months in the making. 80x80. Z4000 transformer. Base 3 and now WTIU (powered by plug, fixed 1 to track block) It is overkill as far as wiring as I have about 10 or so drops for these two loops as I was honestly just practicing developing the skills to even do this. 🤪🙃
