The wheels with RP25 contours can operate on all popular brands of track. The new features include a more powerful and quieter can motor, a 21 - pin plug for DCC - ready models, and Tsunami2 sound with a cube speaker for DCC & sound models. Sound - equipped models have an onboard Tsunami2 DCC/Sound decoder and a cube speaker for great sound quality. They can operate in both DC and DCC, with engine, horn, and bell sounds working in DC. The ALCO RS - 3 was built to compete with other locomotive manufacturers. It had 1,600 hp, more than its earlier design, and was popular for its versatility and reliability among many railroads.

Using this Athearn HO scale model train is easy. First, make sure your track is properly set up. The train's wheels with RP25 contours can run on most popular track brands. If you're using DC power, the engine, horn, and bell sounds will work, but some functions may be limited. In DCC mode, all functions are NMRA compatible. You can use F5 and/or F6 to control the lighting functions like flashing ditch lights and beacons. When it comes to storage, the interior plastic blister safely holds the model. For maintenance, keep the locomotive clean. You can use a soft brush to remove dust from the body, wheels, and other parts. Avoid getting water or other liquids on the electrical components. Check the gears and moving parts regularly to ensure smooth operation. If you have any issues with the DCC or sound functions, refer to the decoder's manual. Overall, with proper use and care, this model train will provide you with a great model - railroading experience.
