This HO scale Athearn ATH73730 SD40 - 2 BNSF locomotive, rebuilt as #7330, comes with DCC and sound. The BNSF SD40 locomotives from #7300 - #7339 were formerly from Canadian National and Grand Trunk Western. Alstom converted them to “SD40 - 2” standards at Point St. Charles, PQ. They were leased from Newcourt Capital USA for ten years and entered service from 9/01/99 to 10/12/99. In 1966, EMD updated its locomotive catalog with new models powered by the 645 diesel engine. The SD40 had 3,000 hp from a turbocharged V16, with 856 built for American railroads, 330 for Canadian, and 72 for Mexican. This model has great features like LED lighting, photo - etched stainless steel windshield wipers, and separately applied wire grab irons. The sound - equipped models offer SoundTraxx Econami sound for an immersive experience.

Using this HO scale locomotive is easy. First, make sure your track is clean and properly connected. If you're using DCC, connect the locomotive to your DCC system using the 21 - pin NEM connector. In DC mode, simply connect the power to run the basic functions like the engine, horn, and bell. For a better experience, you can program multiple unit (MU) lashups using the lead unit's horn, bell, and lights. When it comes to storage, use the interior plastic blister to safely hold the model. Keep it in a dry and dust - free place. For maintenance, clean the wheels regularly with a soft cloth to ensure good electrical pickup. If the sound quality starts to degrade, check the speaker and the DCC decoder. You can also refer to the CV chart in the box to make configuration changes for different functions.
