I am trying to get back into the hobby and are starting with nothing other than cartons of 50 year old HO trains. So i am staring from zero. My space is limited, I can accommodate a 4x8 and have been using SCARM to make some rather boring layouts because I felt constrained by turn radius issues. I have read over and over that anything below an 18" radius does not look right and smaller than 15" will derail and burst into flames unless it is in the yard only, where below 11" causes death there. THEN I stumble across this FANTASTIC layout on You Tube. It claims to be a 4x8 but how can this be? The station tracks is the video must be separate right? What is the real truth here? I am shooting for a 40's era probably somewhere in Appalachia or even Ellicott City type of look (I live around there, we have the Nations oldest remaining passenger train station).
