Using your Athearn SD45 - 2 Santa Fe locomotive is a breeze. First, check the track to make sure it's clean and free of debris. This helps with smooth operation. If you're using DCC, connect your decoder to your DCC system using the 21 - pin NEM connector. For DC operation, just connect the power supply as you normally would. The sound unit will work in both DC and DCC, so you can enjoy the engine, horn, and bell sounds right away. When it comes to running the train, start at a slow speed to get a feel for how it moves. You can adjust the speed and other functions using your controller. Remember, the recommended minimum radius for this locomotive is 22', so avoid sharp turns that could cause derailment. For maintenance, regularly clean the wheels and electrical contacts. You can use a soft, dry cloth to wipe them down. Check the couplers and hoses to make sure they're in good condition and properly connected. If you notice any loose parts or issues with the sound or movement, stop using the locomotive and inspect it carefully. Store the locomotive in its packaging when not in use to protect it from dust and damage.
