This is one of 62 New York Central E8 diesel locomotives as seen by my wife and I at the National NYC Museum in Elkhart, In. recently. General Motors built 450 of these from 1949 to 1954. Each unit was powered by two V-12 Diesel engines and were rated at 2250 HP. Many of these passenger engines were re-geared for freight use as the needs of the railroads changed.  Rich Hane
