I am trying to plan my layout for next christmas. I have a layout that is pretty small, Its only (2) 8x4’s and (1) 4x4 in a L or boot shape formation. I have all postwar trains. I need to find a layout design to accommidate 12 switches and 21 accessories. Are there any good books out there that might tell me how to incorporate all the postwar accessories onto layouts?? Because i just cant get the tracks to line up when adding all these accessories. I think I will only have 2 locos running at 1 time. Where do you get these good books at?? online or hobby shops?? thanks.
