The Athearn ATHG31661 GE Dash 9 - 44CW locomotive is a top - notch model in HO scale. It represents a UP Union Pacific ex CNW #9675 and comes equipped with DCC and Sound Tsunami2. UP features include patched and renumbered former CNW units, correct patch and logo placement, and 'burn marks' according to the prototype road number. There's also a Nathan K3LA horn and 'primered' replacement engine compartment doors. In 1995, Union Pacific took over the Chicago and Northwestern. Repainting of the acquired locomotives was slow, especially for newer units like the Dash 9s. So, patched and renumbered CNW locomotives ran on the UP system for years. Each road number has unique features. For #9675, there's a 'primered' replacement air conditioner and a replacement equipment door from a UP - painted loco with a medium - height snowplow. The Dash 9 - 44CW series has illuminated ground lights, etched walkway steps. The Genesis diesel locomotive offers a range of great features such as coupler cut levers, MU hoses, and a detailed fuel tank. It's DCC - ready with Quick Plug™ technology and has a precision drivetrain. The primed - for - grime models replicate the 'In Service' look, and sound - equipped models have onboard DCC decoder with SoundTraxx Tsunami2 sound. These locomotives were built by GE from 1993 - 2004 and were popular across North America and exported to other countries. The Athearn model captures all the railroad - specific details with superior paint and reliable operation.

Using this Athearn locomotive is easy. Just place it on your HO - scale track. If you're using DCC, connect it to your DCC system to access all the functions like controlling the speed, horn, and bell. In DC mode, you can still enjoy basic engine, horn, and bell sounds. When handling the locomotive, be gentle to avoid damaging the delicate parts like the wire grab irons and fine - scale handrails. For storage, keep it in the provided packaging to prevent scratches. To maintain it, regularly clean the wheels with a soft, dry cloth to ensure smooth electrical pickup. You can also add grime and rust to the primed - for - grime models to make them look more realistic. If you want to change the functions, refer to the CV chart in the box. Remember, the minimum radius for operation is 18 inches, but a 22 - inch radius is recommended for better performance.
