The ATLAS Gold 40005218 is a high - quality N scale model train of the EMD SD50 locomotive. It features the Denver & Rio Grande Western 5508 livery in black and orange. Note that pictures may show a different road number. In the early 1980s, EMD introduced the SD - 50 with a 16 - cylinder, 3500 h.p. engine, achieving power similar to a 20 - cylinder locomotive. The longer frame allowed for better placement of dynamic brake resistors. Visually, the SD - 60 is similar to the SD - 50, but with internal engine changes. You can tell them apart by the door panels. The 'wide nose' or 'safety cab' option came in 1988, with design changes in 1991. This model has many great features. It has deck or pilot - mounted ditch lights as per the prototype, directional lighting, and separate plow and winterization hatches for modelers to install. The blackened wheels, slower - speed motor for scale - like speeds, AccuMate® magnetic knuckle couplers, and golden - white LEDs enhance its appeal. For DCC operation (available only on gold locomotives), it supports all programming modes, includes RailCom and RailComPlus, and has flexible function key mapping. There are 6 DCC function outputs. Sound functionality (also for gold locomotives) offers over 20 sound effects, multiple user - selectable horns, bells, and brake squeals, and ESU’s 'Full Throttle' features for realistic running. The AccuMate® couplers are licensed from AccuRail, Inc.

Using this N scale model train is easy. First, make sure your DCC system is set up properly. You can program the locomotive according to your preferences using the supported DCC programming modes. To start it up, simply send the appropriate commands through your DCC controller. When it comes to the sound, you can select different horns, bells, and other effects easily. For installation, if you want to add the plow or winterization hatch, just follow the basic model - building steps. As for maintenance, keep the locomotive clean. You can use a soft, dry cloth to wipe it down regularly. Avoid getting it wet or exposing it to extreme temperatures. Check the wheels and couplers from time to time to make sure they are in good condition. If there are any issues with the DCC or sound functionality, refer to the user manual that comes with the product.
