Gold locomotives support all DCC - programming modes with RailCom and RailComPlus, 14, 28 or 128 speed steps, and flexible function key mapping. ESU LokSound offers over 20 sound effects, multiple user - selectable horns, bells, and brake squeals, along with manual and automatic notching modes.

Using your ATLAS N Scale EMD GP40 locomotive is easy. First, make sure your DCC system is set up correctly. Connect the locomotive to the tracks and power on the system. Use the DCC controller to adjust the speed and direction of the locomotive. You can also access different functions like lights and sounds through the controller. For sound effects, you can select from various options like horns and bells. When it comes to maintenance, keep the locomotive clean. Regularly check the wheels for any dirt or debris and clean them gently with a soft brush. Avoid using harsh chemicals as they can damage the locomotive. If you notice any issues with the DCC or sound functions, refer to the user manual or contact customer support. Remember to store the locomotive in a dry and safe place when not in use to prevent damage.
