 Athearn's EMD switcher was a rare case of mistaken identity in the
                           company's line for some years.  Jim Boyd discusses the model's prototype attributes in the October '71 issue of Railroad
                           Model Craftsman magazine with his article, "Athearn's SW-?"   Mr. Boyd stated that EMD created and distributed plans for a number of future production models
                           in the mid 1950s.  These scale drawings included EMD's GP40, SD40, SDP40, SD38, SW1000, SW1500, and the never produced
                           DD40A.  The article references these early EMD plans and the fact that the SW1500 displayed in 1955 included a carbody
                           similar to the earlier EMD switchers.  Athearn did their homework early and began production on a number of HO-scale
                           diesels based on these EMD pre-production outlines.  The end result was an SW-7 switcher that was labeled as an SW1500
                           by Athearn for many years, due to this later incorrect drawing.  Also, model railroads received the DD40A that never
                           rode the rails.  Ultimately, EMD produced DD35 and DD35A models and later the DD40AX, but never a DD40A.
