The idea im goin with will be based upon the CM&SF design. Im goin to start with small modules, probably a small yard, switching area. Then build upon it, probably 2x4 modules, the first set will be a 12x2 section. 28" or 30" curves, and single main line with sidings. Sievers benchwork for ease of use, and foamboard top. Ive settled on Atlas DCC for power and control. So, in all, in time hoping to start building, thanks for all replies!!!
