Gold locomotives offer DCC operation with support for all programming modes, RailCom and RailComPlus, flexible function key mapping, and 6 function outputs. They also have ESU LokSound with over 20 sound effects, multiple user - selectable horns and bells, and realistic notching modes.

Using this Atlas Gold N Scale EMD GP9 model is easy. First, make sure your DCC system is set up correctly. You can control the locomotive's speed and functions through the DCC controller following the programming modes it supports. When it comes to sound, just select your preferred sound effects, like the engine start - up or the air horn. For maintenance, keep the locomotive clean. Use a soft brush to remove dust from the wheels and the body. Check the metal wheels regularly for any signs of wear. Avoid exposing the model to extreme temperatures or humidity as it can damage the electronic components. Also, follow the NMRA DCC standards while programming to ensure smooth operation.
