The Athearn ATHG65820 SD45 - 2 model represents the Seaboard Coast Line locomotive SCL # 2053. It's in HO scale and comes with DCC and Sound Tsunami2 features. The Seaboard Coast Line's predecessor, the Atlantic Coast Line, started buying SD45s in 1968, and the trend continued after the merger with Seaboard Airline. By 1974, EMD introduced the upgraded SD45 - 2, and SCL bought 15 of them. This locomotive has a host of great features. It has coupler cut levers, MU hoses, and trainline hoses. The see - through cab windows give a view of the full cab interior. There are walkway treads, windshield wipers, lift rings, and wire grab irons. The sander lines and fine - scale Celcon handrails add to its realistic look. The detailed fuel tank with fuel fillers, gauges, and breather pipes is a nice touch. It comes with McHenry® scale knuckle couplers that are Kadee® compatible. The DCC - ready feature uses Quick Plug™ plug - and - play technology with a 21 - pin NEM connector. It's scaled from prototype resources, accurately painted, and has a Genesis driveline with a 5 - pole skew wound motor, precision machined flywheels, and a multi - link drivetrain. All - wheel drive with precision gears ensures smooth and quiet operation, and all - wheel electrical pickup provides reliable current flow. The wheels with RP25 contours work on all popular track brands. LED lighting makes it look realistic, and the heavy die - cast frame offers greater traction and pulling power. The packaging is designed for safe storage, and it's fully assembled and ready to run. The minimum radius is 18', and the recommended radius is 22'. For sound - equipped models, they have an onboard DCC decoder with SoundTraxx Tsunami2 sound. The sound units work in both DC and DCC. Engine, horn, and bell sounds work in DC, and all functions are NMRA compatible in DCC mode. There's precision slow - speed control, and you can program a multiple unit (MU) lashup with lead - unit - only horn, bell, and lights. Many functions can be changed via Configuration Value (CV) changes. The SD45 - 2 was a great success, an upgrade in EMD's 'Dash 2' line, and lasted longer on rosters than most SD45 units. Product specs include lighted LED, Sound Tsunami2, sub - brand GENESIS, DCC equipped, HO scale, 6 axles, era 1971 - 1990, and prototype manufacturer EMD.

Using this Athearn HO scale model train is a breeze. Since it's fully assembled and ready to run, you can simply place it on your track. If you're using DC, the engine, horn, and bell sounds will work right away. For DCC operation, it's DCC - ready with the Quick Plug™ plug - and - play technology and a 21 - pin NEM connector. You can connect it to your DCC system easily. When running it, keep in mind the minimum radius of 18' and the recommended radius of 22' for smooth operation. As for maintenance, keep it clean. You can use a soft, dry cloth to wipe the locomotive. Avoid using harsh chemicals that might damage the paint or details. If you need to adjust any functions, you can do so via Configuration Value (CV) changes, but make sure to follow the instructions carefully. Store it in the provided packaging when not in use to protect it from dust and damage. And always handle it gently to prevent any parts from breaking off.
