I'm in the planning stages to build a removable modular layout in my 20 x 20 family room. The modules will be 2 x 6 and 2 x 4 rectangular units, with special curved units in the corners, set up against the walls. I had originally planned to use Atlas 2-rail, but with the limited availability of this track and most of my engines and rolling stock being 3-rail, I decided to use 3-rail track on hand. I have about 150' of Gargraves and 072, 060, 048 loops and 20' of Fastrack. I'm looking for opinions on what track system would be the best to use. Thanks for your input.
