After having completed a small 2x2 N scale circle for my Sunday school room, it’s time to plan for 2020 and how to go bigger! I’m looking at building a modular layout, using the 2’x2’ pink foam board from Lowe’s. Looking at using 3 Or 4 for a 6’x2’ or 8’x2’ layout, with two separate loops. I’m looking for ANY & ALL advice on this type of layout- wiring, joining the sections, track, etc.. Thanks all and Merry Christmas from Texas!
