Here are questions for our resident Lionel experts. Is there some way to tell the given radius of a piece of Lionel curved tube-type track? I had heard someone mention that the number of ties indicates curve radius - can anyone help me out here? The reason I ask is that I am trying to plan a shelf-around-the-room idea, and I'd like to have a curve radius wide enough to run (eventually...) some of the closer-to-scale passenger equipment. (NOT the super short 027 stuff) These require either 042 or 054 radius curves; I'm not even too sure at this point, but I'd like to know how to find the correct pieces of track when I'm ready to go. Hope someone can help.
