The ATLAS Gold 40005273 EMD GP40, a high - quality N Scale locomotive, is a great addition for model train enthusiasts. It's modeled after the Electro Motive Division's GP - 38 and GP - 40 diesels. The GP - 38, with its 2000 horsepower, was introduced in the late 1960s and built through the early 1970s, still in service across North America. Recognize it by two radiator fans on the long hood and two small exhaust stacks. The GP - 40, a 3000 horsepower locomotive from the same era, features three full - size radiator fans on the rear of the roof. This model represents CP Canadian Pacific #4600 and comes with DCC & Sound (note pictures might show a different road number). Key features include directional lighting, walkway safety tread, blackened metal wheels, a Scale Speed™ motor, AccuMate® knuckle couplers, dynamic brakes (railroad - appropriate), and golden - white LEDs. For gold locomotives, it supports all DCC - programming modes, has RailCom and RailComPlus, flexible function key mapping, and 6 DCC function outputs. The ESU LokSound offers over 20 sound effects, multiple user - selectable horns, bells, and brake squeals, along with manual and automatic notching modes for realistic operation.

Using your ATLAS Gold EMD GP40 model is easy. First, make sure your DCC system is set up correctly according to the product's DCC operation features. You can select different speed steps and address the locomotive easily. When running the train, enjoy the realistic sound effects like engine start - up and the air horn. For the best experience, operate it on clean and well - maintained tracks. When it comes to maintenance, regularly clean the blackened metal wheels with a soft brush to ensure smooth movement. Check the AccuMate® knuckle couplers for any signs of wear and replace them if needed. Store the locomotive in a dry and dust - free place when not in use. Remember, if you want to change the sound settings or programming, refer to the DCC and ESU LokSound features provided. Have fun with your model train!
