This is great, I’m moving my layout into a new space which is 8’ 6” x 20’, with no structural interference. My wants are: a rise to a second level from a lower level with at least two mainlines with a crossover. Minimum curves O54” maximum I think would be O72” to allow the longest straight run. May use old style tubular track although Atlas is not out of the question. At least a tunnel and use of my center span lift bridge and 24” truss bridges. Need an engine service area with a single or double stall engine shed. Gantry crane spur it siding and a trackside crane. Passenger and freight stations. I have the Menards power station so that need a place where coal or tankers can offload through it. At least two spurs or sidings to store full length consists. I am okay with a lift out bridge. Era is steam/early diesel.
Any help is appreciated since the layout Obsidian posted is appealing.
