The Feather River is housed in a 12ft x 12ft room/shed built for it.... its around the walls, double track design, and has a 6ft x 6ft corner/ peninsular section a 18ft(approx) yard area, broken by imagination, into 2 yards with 4 tracks each track holding 2 trains with up to 14 cars per train. the FR is on 2 levels, (soon to be 2 1/2) and has 3 industrial tracks, it can be run from 4 locations around the lay out and the industries can be run by separate operators on local throttles, so my layout can be run by me on my Todd, or by up to 6 operators and a dispatcher. I can run by card system, by the silly bugger (do as we like) system, or by time table system, or any other way i/we want, just to have fun....the walk ways around the layout are a narrow 28 inches my girth is 40 inch and I can get around with out to much trouble....but the best layout design, IMO is any design that works for you.....have a good day running your layouts...stevesign1 sign1 sign1 :thumb: :thumb: :thumb:
