ATLAS Gold 40005220 presents the EMD SD50 SP Southern Pacific #5504 in striking gray and red colors, featuring ditch lights, DCC, and sound in N Scale. Note that pictures might show a different road number. In the early 1980s, EMD launched the SD - 50 with a 16 - cylinder, 3500 h.p. engine, getting the power of a 20 - cylinder locomotive. The longer frame relocated dynamic brake resistors to a cooler area. Visually, the SD - 60 is similar to its predecessor, but the 645F engine was replaced by the 710G. You can tell them apart by the door panels. The SD - 50 has four latched doors in six panels, while the SD - 60 has six in eight. The 'wide nose' or 'safety cab' was an option for US railroads in 1988, and Union Pacific got the first units in 1989. In 1991, the nose contour changed for better crew visibility. Burlington Northern was the first to receive the revised model. This model has great features like ditch lights, directional lighting, separate plow and winterization hatch, blackened wheels, a slow - speed motor, AccuMate® magnetic knuckle couplers, and Golden - White LEDs. Gold locomotives have advanced DCC operation features including support for all programming modes, RailCom and RailComPlus, flexible function key mapping, and 6 function outputs. Sound functionality offers over 20 effects, multiple user - selectable horns and bells, and ESU’s 'Full Throttle' features for a realistic experience. AccuMate® couplers are licensed from AccuRail, Inc.

Using your ATLAS N Scale EMD SD50 locomotive is easy. First, if you're using DCC, make sure your DCC system is set up correctly according to the instructions. You can control the speed and direction of the locomotive using your DCC controller. The directional lighting will automatically change based on the direction of movement. For the sound features, select your preferred horn, bell, and other sound effects through the DCC system. When it comes to maintenance, keep the locomotive clean. You can use a soft brush to remove dust from the body, wheels, and details. Make sure the wheels are clean as dirty wheels can affect the electrical connection and performance. Store the locomotive in a dry and cool place to prevent any damage. If you need to replace the AccuMate® couplers, follow the instructions provided with the couplers carefully. And always remember to handle the locomotive gently to avoid any breakage of the delicate parts.
