I recently found a mess of old Atlas N scale track while cleaning out a storage unit. I thought it might be fun to build a new micro in N scale. I am going to build a 24 inch by 24 inch baseboard with either styrofoam or foamcore risers to create elevation. In essence, it's a pizza layout with a branch line running to a mine at the highest elevation on the layout. No precise grades or curve radius, I'm just trying to visualize the layout with these 3D track plans.
