The Athearn Genesis ATHG31793 is a remarkable HO scale model of the GE AC4400CW locomotive, specifically representing UP Union Pacific #6837 with DCC and sound features. UP has been a leader in new locomotive technology. When GE introduced the AC version of their DC Dash 9 locomotives, UP ordered some for testing in 1994 and more in 1996. Through mergers, UP became a major owner of AC4400s. The model has many UP - specific features like a large plow, low - mount number boards, and pilot - mounted ditch lights. The AC4400CW series locomotive features DCC - ready Quick Plug™ technology, accurate paint schemes, and lifelike LED lighting. It also has detailed components such as etched walkway steps, animated roller bearing caps, and flexible rubber hoses. Sound - equipped models come with an onboard DCC decoder with SoundTraxx Tsunami2 sound and dual cube speakers. The AC4400CW was produced from 1993 to 2004 and was used by many railroads across North America. Athearn has reproduced dozens of variations of this locomotive with precision tooling. Specifications include 6 axles, DCC and sound capabilities, LED lighting, and an HO scale.

Using this Athearn Genesis HO scale locomotive is a breeze. First, you can easily connect it to your DCC system with the Quick Plug™ technology. If you're using a DC system, the sound functions like engine, horn, and bell still work. When setting up, make sure the locomotive is on a clean and flat track. For best results, use tracks that are compatible with RP25 contour wheels. As for maintenance, keep the locomotive clean. You can use a soft brush to remove dust from the body, wheels, and details. Avoid getting water or harsh chemicals on the model. When storing, use the provided packaging to keep it safe. If you want to change the settings, you can refer to the CV chart included in the box. And if you plan to do a multiple - unit (MU) lashup, follow the instructions to program it so that only the lead unit controls the horn, bell, and lights.
