My N scale multi-deck NYC Scioto Valley Division layout has been incorporated as a sample layout in the TrainPlayer program as one of their Fall 2010 featured layouts. [The other featured layout is also terrific: Vince Lee's compact Erie RR 28th Street Terminal layout from the July 2010 Railroad Model Craftsman magazine.]
TrainPlayer allows users to operate virtual layouts on their own computers, including a large number of published layouts. Users can also "draw" TrainPlayer tracks over any image or in their own designs.
It's a neat program and a few of my layouts have already been included in the software. It's always interesting to see how technology is broadening the model railroading hobby.
