The Athearn ATHG82374 is an HO scale model of the GP9 locomotive from the Great Northern. It's equipped with DCC and Sound Tsunami features. The GN features include a winterization hatch with a horn on top, long hood - forward operation, a 'nail' style antenna, and GN style fuel tank skirts. In 1967, Great Northern adopted the Big Sky Blue paint scheme, and some GP9 locos got this treatment. In 1970, GN merged with other roads to form Burlington Northern, and the Big Sky Blue units lasted for a while with a simple BN patch. Road number #682 has snowplows at both ends, is non - dynamic, and has a bell in the center of the long hood. The GP9 series locomotive comes with a full cab interior, wire grab irons, coupler cut levers, and many other detailed features. It has a Genesis driveline for smooth operation, all - wheel drive and electrical pickup, and heavy die - cast frame for better traction. Sound - equipped models have an onboard DCC decoder with SoundTraxx Tsunami2 sound, dual cube speakers, and can operate in both DC and DCC. The prototype of the GP9 evolved from the GP7 in 1954, and many railroads rebuilt GP7s and GP9s for continued service.

Using this Athearn HO scale GP9 locomotive is easy. First, connect it to your DCC or DC power system according to the included instructions. If you're using DCC, you can enjoy full functions and use the Quick Plug™ technology. In DC mode, the engine, horn, and bell sounds will still work. When operating, make sure the track radius meets the minimum 18 - inch requirement, though 22 - inches is recommended for better performance. As for maintenance, regularly clean the wheels and electrical contacts to ensure good current flow. Check the body for any loose parts and tighten them if needed. Store the model in its original packaging to keep it safe. Don't expose it to extreme temperatures or moisture. If you want to change some functions, refer to the CV chart in the box and make changes via Configuration Value adjustments.
