Maybe I have too much time on my hands and Not sure if anyone else has done this , build a scale model of the layout you want to build. This is what I hope to get off the floor and onto a platform one day. This standard gauge layout measures 16'x6' and is approximately 3' tall and The model is 12"x32". Each of my structures are within a fraction of an inch to being scale. My eyesight is not what it once was . There are two home made stations, each being 3' long , a homemade water tower made from an old coffee can, a sand tower and a forest lookout tower. This simple layout is basically a figure 8 with a connecting loop around it . The long straight run will have ten (10) 101 single span bridges all connected to be a 140 inch bridge . I got a large box of them at a local auction a few years back. Not shown on the model are my villas ,bungalows , street lights ,signals, home made telephone polls and trees . Anyway, its been a fun little project to do and it has kept me in the dreaming state like a kid again. I currently don't have the space for it , I do have all the frame work and supports for it from an O gauge layout many years ago.
