Explore the Athearn ATHG31657 AC4400CW HO scale model train, representing the Southern Pacific #239 with DCC and Sound Tsunami features. This locomotive is packed with authentic details. SP features include a Nathan P - 3 Horn, high number boards, and early body characteristics. It has unevenly spaced rear grab irons, a central air intake in the forward position, and an early no - notch bolted on fuel tank. The engineer’s side has an extended radiator hatch, and there's a Prime Air Dryer. It also comes with GE Hi - Adhesion trucks and modified outside struts on the trucks. The alternating flash front ditch lights work in DCC. Built between April and November 1995, the Southern Pacific ordered 279 AC4400CWs from General Electric, marking their first foray into AC technology and their largest single locomotive order. Road - number - specific features like unique spare knuckle boxes on the rear pilot for #114 and #239, and an additional handrail above the capacitor box for #336 add to its charm. The AC4400CW series locomotive is fully assembled and ready to run. It has DCC - ready features with Quick Plug™ technology and a 21 - pin NEM connector. The model is accurately painted and printed, with LED lighting set to lifelike levels. It has illuminated number boards, ground lights, walkway lights, and marker lights. The etched walkway steps, animated roller bearing caps, and flexible rubber hoses are just some of the many fine details. Sound - equipped models come with an onboard DCC decoder with SoundTraxx Tsunami2 sound, dual cube speakers, and can operate in both DC and DCC. The primed - for - grime models mimic the look of 'In Service' equipment, making them great for adding grime and rust effects. The AC4400CW was a staple of modern railroading from 1993 to 2004, and Athearn has captured all its variations with precision tooling.

Using your Athearn AC4400CW model train is a breeze. If you're using DC power, just connect it to your power source, and the engine, horn, and bell sounds will work right away. For DCC operation, connect it to your DCC system, and you'll have access to full DCC functions. When storing the model, keep it in its original packaging, which is designed to hold it securely. Be careful when handling the model, especially the fine - scale Celcon handrails and wire grab irons as they can be delicate. To maintain the model, use a soft, dry cloth to clean the exterior. Avoid using harsh chemicals as they may damage the paint and details. If you want to add grime and rust effects to the primed - for - grime models, start with light layers and build up gradually. For the sound unit, make sure the batteries (if applicable) are properly installed and replaced when needed. Enjoy your model train and the hours of fun it will bring!
