Journey back to the 1970s as first and second generation diesels of the Frisco, Missouri Pacific, Katy (M-K-T), and T.R.R.A. railroads ply the rails. Lots of local switching keeps crews busy at Midwestern industries. A steel mill, scrap dealer, cement factory, quarry, brewery, various grain elevators, mill, shoe factory, food wholesaler and other rail-served industries dot the landscape. Sound-equipped locomotive consists head manifest freights, locals, turns, extras, and a passenger train; all contributing to the operating action on this signaled, double-decked, CTC dispatcher-controlled HO-scale layout.
The difference between genius and stupidity is that genius has its limits.
