The Athearn ATHG82330 GP9 TH&B #403 is an HO scale model train with DCC and Sound Tsunami features. TH&B's GP9s, equipped with steam generators, started service in 1954 and ended steam operations on this small Canadian railroad. Their passenger - service time was short, and they served in freight service until the CP Rail era. The TH&B locomotive has features like steam generator intake and exhaust, a long - hood nose - mounted bell, separate ACI plates, and roof - mounted air tanks. The locomotive itself comes with numerous detailed features. It has trainline and MU hoses, coupler cut levers, and drop steps. It also has fine - scale handrails, wire grab irons, and see - through cab windows with a full interior. The model is fully assembled and ready to run, with DCC - ready Quick Plug™ technology and a 21 - pin NEM connector. It has an accurate paint scheme, a body - mounted McHenry operating scale knuckle coupler, and a Genesis driveline for smooth operation. Sound - equipped models allow function changes via CV and come with a CV chart. The GP9 prototype was an upgrade from the GP7 in 1954. Many railroads rebuilt GP7s and GP9s for cost - effective continued service. Specifications include DCC ready with a 21 - pin NEM connector, sound ready, an EMD prototype manufacturer, 4 axles, LED lighting, a minimum age recommendation of 14 years, and no assembly required.

Using this Athearn HO scale model train is easy. Since it's fully assembled and ready - to - run, you can just place it on your track and start operating right away. If you want to use the DCC features, connect it using the 21 - pin NEM connector and the Quick Plug™ technology. For the sound function, refer to the CV chart in the box to make changes to different functions. When handling the train, be gentle as it has many fine - scale details like handrails and wire grab irons. Avoid dropping it or applying too much force. For storage, use the provided packaging that securely holds the model. To maintain the train, regularly clean the wheels with a soft, dry cloth to ensure smooth operation. If any parts get damaged, replacement parts are available. Remember, this product is recommended for users aged 14 years and above due to its small parts and detailed features.
