The Athearn ATHG31647 AC4400CW locomotive is a remarkable HO scale model representing the Chicago & North Western #8801 with DCC and Sound Tsunami features. The CNW version has unique features like the Holden K5H Horn, early body design, and a desk - style control stand. The fuel tank is bolted to the frame and lacks a notch. It also has unevenly spaced rear grab irons and front ditch lights. Chicago & Northwestern's AC4400CW units were painted in the attractive 'Lighting Stripe' scheme with an Operation Lifesaver decoration on the long hood. The AC traction was perfect for the heavy coal trains from the Powder River Basin, and many units lasted long after the UP acquisition. The AC4400CW series locomotive is fully - assembled and ready - to - run. It features Quick Plug™ plug - and - play technology with a 21 - pin NEM connector. The model is accurately scaled from prototype resources, with realistic paint schemes and LED lighting. It has illuminated number boards, ground lights, walkway lights, and marker lights. The details are amazing, including etched walkway steps, animated roller bearing caps, and flexible rubber hoses. The Prime for Grime models mimic 'In Service' equipment, with faded base colors and are great for adding grime and rust. The sound - equipped models have an onboard DCC decoder with SoundTraxx Tsunami2 sound, dual cube speakers, and work in both DC and DCC. The AC4400CW was a staple of modern railroading from 1993 to 2004. Athearn has reproduced dozens of variations with precision tooling, making this the new flagship model.

Using this Athearn AC4400CW locomotive model is easy. If you're using a DCC system, simply connect it to your setup using the Quick Plug™ technology with the 21 - pin NEM connector. For DC operation, it also works well, and you can enjoy basic engine, horn, and bell sounds. When storing the model, make sure to use the secure packaging provided to keep it safe. For maintenance, gently clean the model with a soft brush to remove dust. Check the wheels regularly for any debris that might affect its smooth operation. If you want to add grime and rust to the Prime for Grime model, start with a light touch and build up the effect gradually. Avoid getting the model wet as it can damage the electrical components and the paint. With proper care, this locomotive will give you years of enjoyment on your HO scale tracks.
