I am preparing to build a fairly large basement layout. I have gone through well over 100 different designs and settled on one. However, I keep feeling like I'm not making the best use of space available. Here is the Lower Level (Click to Enlarge): Upper Level: My railroad is a freelanced regional carrier base in the early 1970's in the Southern and Central part of West Virginia. Primarily a coal hauler with plenty of steel, manufacturing and chemical traffic. Also features bridge traffic from the PC and N&W. My design is a two-level layout that mostly runs around the walls from point-to-point. The current track plan is of a nolix design, but if I proceed with this design, I believe I will be building a helix instead to maximize scenic space around Big Chimney and Elkview. The basement ceiling is about 86" and 80" at the center beam and lowest ductwork, so a mushroom design may be out of the question. I feel like I'm not maximizing the available space, especially in the area of staging yards. Questions, critiques, changes all accepted. I am also attaching a blank floor plan in case somebody wants to try sketching something totally different. I'm an open book, thanks in advance for your input!
