The Lehigh & Keystone Valley Model Railroad Museum is located in Bethlehem, Pa. It’s a 4500 sq. ft. HO scale layout featuring railroads that ran through the Lehigh Valley in the 1960s and 1970s: Lehigh Valley, Reading and Central New Jersey. The layout uses NCE DCC and is fully detected and signaled using Digitrax components. It has a CTC center with a dispatcher, computer and 6 monitors controlling train movements. The layout was featured in the September 2013 issue of Model Railroader magazine on the cover and pages 44-51.
