I am ready to begin drawing this plan on my cardboard covered L-Girder benchwork. The blue track will be at 44" high and the green at 48". The long green sidings will have to be buried and have to be accessible from underneath. I am planning to run the track for several months to get all the kinks worked out before scenery. I really want two main line loops for continuous operation. The width of the room is making this difficult only have 9' at the tightest spot. My original designs consisted of a large table against the long wall but I found accessing the entire table was very difficult without access holes. I have switched to a preferred walk around design. The single green line ending at the door will be for DCC programming and possibly staging since it will be near the control panel. I have tried to avoid radius turns less than 24" to prevent problems with long cars and locos. Turnouts will be Peco #6's in most cases. Grade between the green and blue lines is 2% on the purple line. Each loop has a bi-directional reversing loop in the design which will be wired/managed with a Digitrax Quad board. Please post any thoughts, opinions or suggestions that you have and I will be glad to review your comments. Thanks in advance for taking time to review my plans.
