The Athearn ATH73732 SD40-2 BNSF locomotive, rebuilt as #7336, is a high - quality HO scale model train. The BNSF SD40 #7300 - #7339 were originally from Canadian National and Grand Trunk Western. They were converted to SD40 - 2 standards by Alstom at Point St. Charles, PQ and leased from Newcourt Capital USA for ten years, starting service between 9/01/99 and 10/12/99. In 1966, EMD launched new locomotive models with a 645 diesel engine. The SD40 had 3,000 hp from a turbocharged V16, with many built for American, Canadian, and Mexican railroads. This model features LED lighting, photo - etched stainless steel windshield wipers, and separately applied wire grab irons. It has excellent details like a 4000 - gallon fuel tank and Flexicoil - C trucks. The sound - equipped models come with an onboard DCC decoder and SoundTraxx Econami sound, offering a great audio experience. It's DCC - ready with Quick Plug™ technology and a 21 - pin NEM connector for easy operation.

Using your Athearn ATH73732 SD40 - 2 BNSF HO scale locomotive is easy. First, place it on the track with a minimum radius of 18 inches (22 inches recommended). If you're using DCC, connect it to your DCC system using the Quick Plug™ and 21 - pin NEM connector. For DC operation, just connect it to a DC power source. When operating the sound - equipped model, you'll enjoy engine, horn, and bell sounds. In DCC mode, you can use functions like F5 and F6 for lighting. To program multiple unit (MU) lashups, follow the instructions and set the lead unit's horn, bell, and lights. For maintenance, keep the locomotive clean. Use a soft brush to remove dust from the body, wheels, and mechanical parts. Check the electrical connections regularly to ensure a reliable current flow. When storing, use the interior plastic blister to hold the model safely. Remember, some functions are limited in DC mode, so if you want full functionality, use DCC.
