I have my layout planned to a point. I have the size of my table figured out and will start building it soon. I have a "L" shaped setup in a spare room in the basement. The longest leg of the L is 11'-5" and the shortest is 10'-1" the depth from front to back 4'. I have my layout drawn to scale all except the track. I free handed that in just to get the basic track setup down. I will have a loop that runs the outside of the L with a second inside that with some variation with the elevation on the outside. I have a yard a the "elbow" of the L shape and plan on a town on one end and a farm scene on the other - eventually. I'm going to use the Atlas 83 Flex Track and I'm going DCC. I am completely clueless when it comes to the radius. I was told by some very reputable guys that I want at least a min. of a 22" radius - possibly 24" so I can utilize longer cars and engines if I desire. So where can I get some templates for those radius so I can visualize this setup? Also, I'm in the dark about turnouts and what the numbers mean. I plan on some turnouts in the corners for parking cars and for the yard. How are the track radius measured - from the center of the track the outside rail or the inside rail??? Anyway, if I can find some templates of the radius and turnouts, I think I can piece it together and have an accurate idea of how much track I'll need and all the switching and whatnot. Thanks!
