The Athearn ATHG31677 is a remarkable HO scale model train of the GE Dash 9 - 44CW, representing Union Pacific #9713. It comes equipped with DCC and Sound Tsunami2 features. The UP locomotives have unique features. Some are patched and renumbered former CNW units, with patch, logo placement, and 'burn marks' per prototype road #. They also have a Nathan K3LA horn and 'primered' replacement engine compartment doors. In 1995, after Union Pacific bought Chicago and Northwestern, re - painting of the acquired locomotives was slow, so patched and renumbered CNW locomotives ran on the UP system for years. Different road numbers have their own distinct features. For example, #9675 has a 'primered' replacement air conditioner and a medium - height snowplow. The Dash 9 - 44CW series locomotives are built with illuminated ground lights, etched walkway steps. The Genesis diesel locomotive models have a wide range of great features like coupler cut levers, see - through cab windows, and a full cab interior. They are DCC - ready with Quick Plug™ technology and 21 - pin NEM connector. The sound - equipped models have an onboard DCC decoder with SoundTraxx Tsunami2 sound and dual cube speakers. Built from 1993 to 2004, the prototype Dash 9 - 44CW was a major North American mainline freight locomotive with 3668 units built. This Athearn model matches its prototype's impressiveness with railroad - specific details and superior paint colors.

Using this Athearn model train is easy. First, make sure you have a compatible power source. If you're using DCC mode, connect the train to your DCC system. In DC mode, you can still enjoy basic functions like engine, horn, and bell sounds. When setting up the train on your track, ensure the minimum radius of the track is at least 18 inches, but a 22 - inch radius is recommended for better performance. As for maintenance, keep the train clean. You can use a soft brush to remove dust from the body, wheels, and mechanical parts. Check the couplers regularly to make sure they are working properly. If you notice any loose parts, tighten them gently. Store the train in its original packaging when not in use to protect it from damage. When adding grime and rust effects to the primed models, use appropriate modeling paints and techniques. Also, follow the instructions in the CV chart for any configuration changes in the sound - equipped models.
