It runs smoothly and quietly with all - wheel drive and electrical pickup. The DCC - ready models use Quick Plug™ technology and have a 21 - pin NEM connector. New features are a more powerful and quieter can motor, 21 - pin plug in DCC - ready models, Tsunami2 sound with a cube speaker in DCC & sound models, and long - lasting LED lighting. Sound - equipped models have an onboard Tsunami2 DCC/Sound decoder, a cube speaker for great sound, and work in both DC and DCC. The prototype RS - 3 was built by ALCO to compete with others, offering 1,600 hp. It's highly detailed, injection - molded, painted realistically, fully assembled, and ready to run.

Using this Athearn RS - 3 model is easy. First, make sure your track is clean and properly connected. Place the model on the track, and if you're using DC power, simply connect the power source and adjust the speed. For DCC operation, you'll need a compatible DCC system. Use the controller to operate functions like lighting, horn, and bell. When it comes to storage, keep the model in its interior plastic blister to prevent damage. For maintenance, regularly clean the wheels and electrical contacts with a soft, dry cloth. Check the couplers for any signs of wear and replace them if necessary. Avoid exposing the model to extreme temperatures or humidity as this can damage the components. If you encounter any issues with the sound or DCC functions, refer to the decoder's manual or contact customer support.
