This Athearn ATHG65638 HO scale model is a GP39-2 locomotive featuring CSX/Ex-RDG Patch #4316, equipped with DCC and Sound Tsunami2. CSX units, acquired in the early 1990s, were great for local and switching duties. Some were patched with CSX lettering and renumbered, then repainted into CSX's 'YN2' scheme. The road number 4316 has a replaced CSX K5 chime horn, original Blomberg B trucks, and unique patched art. All units are powered with a heavy die-cast frame for better traction. It has DCC-ready Quick Plug™ technology, and the DCC+sound units come with a factory - installed SoundTraxx Tsunami2 decoder. The sound is compatible with both DCC and DC operation. The locomotive is highly detailed, with separately applied parts and a detailed fuel tank. It has all - wheel drive and electrical pickup, and runs smoothly on popular tracks. The sound - equipped models have many features like pre - installed SoundTraxx Tsunami2 decoder and NMRA - compatible functions in DCC mode.

Using this Athearn locomotive is easy. First, make sure your track is clean and properly connected. If you're using a DCC system, connect the locomotive to your DCC controller according to the instructions. The locomotive is ready to run right out of the box, no assembly required. For sound functions, the sound units work in both DC and DCC, but some functions are limited in DC. When programming a multiple - unit (MU) lashup, follow the included CV chart to set the horn, bell, and lights on the lead unit. Be careful when handling the locomotive as it has delicate separately applied parts. Avoid dropping or hitting it. To maintain the locomotive, regularly clean the wheels and electrical contacts to ensure reliable current flow. If you need to replace any parts, replacement parts are available. Keep the locomotive in a dry and dust - free place when not in use. It's recommended for users aged 14 years and above due to small parts and the complexity of DCC and sound systems.
