Attached is my new layout space. I have left 3-4 ft for walking around the layout. The layout itself is "L" shape. I would greatly appreciate the input of some of the experts from the forum members. My goal is 3-4 interconnecting independent loops (using Lionel tubular 072, 060 (k-line), 054, and only 072 switches. Finally, a totally elevated "Chicago Loop" using "Super O" . This is a toy train layout using most postwar and modern accessories. But I'd still like to run the Big Boy and 18" passenger cars on some portions.
Thank you in advanced.
PS: I have RR Track and SCARM software.
