The ATLAS 40004210 is an N scale model of the GE Dash 8-40C locomotive, specifically representing Lancaster & Chester #9146 in a beautiful gold color. It comes with DCC and sound features. The original Dash 8-40C diesel locomotives, built by General Electric for Union Pacific in the late 1980s, had an enlarged exhaust stack and dynamic brake grids in a square - like unit behind the cab with an enlarged equipment blower fan. These 4,000 hp six - axle engines are still in use in North America today. The Dash 8-40CW, a follow - up from 1989 to 1993, introduced GE's wide - nose 'North American Safety Cab' and was bought by major railroads like Conrail, CSX, Santa Fe, and Union Pacific, and is still used in mainline and heavy - haul freight service. This model has great features such as a separate coupler cut lever, directional lighting with golden white LEDs, painted safety rails, blackened metal wheels, a 5 - pole skewed armature motor with dual flywheels and low friction mechanism, and factory - installed AccuMate® magnetic knuckle couplers. For gold locomotives, it supports all DCC - programming modes, includes RailCom and RailComPlus with different speed steps and addressing options, has flexible function key mapping, and 6 individually - mappable DCC function outputs. It also adheres to NMRA DCC standards. In terms of sound, there are over 20 sound effects, up to 16 user - selectable horns, 2 user - selectable bells, and 2 user - selectable synchronized brake squeals, along with ESU's 'Full Throttle' features for realistic running. The AccuMate® couplers are licensed from AccuRail, Inc.

Using this ATLAS N scale model train is easy. First, make sure your DCC system is set up properly. You can connect the locomotive to the tracks and use your DCC controller to start, stop, and control its speed. The DCC functionality allows you to program different settings according to your preference. For the sound, use the function keys on your controller to activate different sound effects like the engine start - up, bell, and horn. When it comes to maintenance, keep the tracks clean to ensure smooth running. You can use a track cleaner to remove any dirt or debris. For the locomotive, gently clean the wheels with a soft cloth to keep them in good condition. Avoid exposing the model to extreme temperatures or humidity as it can damage the components. If you need to replace the couplers or any other parts, make sure to follow the instructions carefully and use the appropriate tools. And always refer to the official documentation for more detailed information.
