The ATLAS Gold 40005278 is a high - quality N Scale locomotive. It's modeled after the Electro Motive Division's GP - 38 and GP - 40 locomotives. The GP - 38, introduced in the late 1960s and built through the early 1970s, still serves in North America. It's recognized by two radiator fans on the long hood and two small exhaust stacks. The GP - 40, produced in the same period, has 3000 horsepower and three full - size radiator fans on the roof rear. This model comes with many great features. It has directional lighting, walkway safety tread, blackened metal wheels, a Scale Speed™ motor, and factory - equipped AccuMate® knuckle couplers. Dynamic brakes are included as appropriate for the railroad, and it uses golden - white LEDs. For DCC operation (only for GOLD LOCOMOTIVES), it supports all DCC - programming modes, includes RailCom and RailComPlus with various speed steps and addressing options, has flexible function key mapping, and six individually - mappable DCC function outputs. It follows all NMRA DCC standards. The ESU LokSound (only for GOLD LOCOMOTIVES) offers over 20 sound effects like engine start - up and shutdown, prime mover sounds, bell, air horn, etc. There are multiple user - selectable horns, bells, and synchronized brake squeals, and manual and automatic notching modes for a realistic experience. Note that pictures may show a different road number.

Using this ATLAS Gold N Scale locomotive is easy. First, make sure your DCC system is set up correctly. Connect the locomotive to the track and power it on. You can control the locomotive's speed and direction using your DCC controller. To enjoy the sound features, set the appropriate sound settings on your DCC system. When it comes to the function keys, you can customize them according to your preference. As for maintenance, keep the locomotive clean. Use a soft brush to remove dust from the body, wheels, and electrical contacts regularly. Store the locomotive in a dry and cool place to prevent damage. Avoid using harsh chemicals or abrasive materials when cleaning. If you notice any issues with the locomotive's movement or sound, check the connections and the DCC system settings first.
