I need assistance in locating a series of articles about building O scale in a small space. This was definitely a small 2 rail 1 1/2 level switching Layout that featured a 44 tonner switching boxcars, flats and hoppers. I say 1 1/2 levels because it was almost a double oval where the back portion had 2 levels; one was raised 3 inches and below the lower level sunk in a tunnel 3 inches just giving clearence to ps1 boxcars and ps2 hopper cars. Both levels had industrial Spurs and a huge industry with two facades acted as a scenic divider on a45 degree angle to make the layout look bigger than it was.
I can't remember if it was 48/ft or o scale trains magazine either and the construction of the layout spaned at least two issues.
Any assistance would be greatly appreciated.
