ATLAS Gold 40005222 presents the EMD SD50 SP Southern Pacific #5517 in eye - catching gray and red colors, designed for 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, achieving power previously from a 20 - cylinder locomotive. The new, longer frame relocated dynamic brake resistors to a cooler area. Visually, the SD - 60 is similar to the SD - 50, but with internal changes. The SD - 50 has four latched doors in six door panels, while the SD - 60 has six in eight. The 'wide nose' or 'safety cab' was an option in 1988 and evolved in 1991. This model comes with great features like deck or pilot - mounted ditch lights, directional lighting, separate plow and winterization hatch, blackened wheels, a slower - speed motor, AccuMate® magnetic knuckle couplers, and Golden - White LEDs. Gold locomotives offer amazing DCC operation features such as support for all DCC - programming modes, RailCom and RailComPlus, flexible function key mapping, and 6 function outputs. Sound functionality includes over 20 sound effects, user - selectable horns and bells, and ESU’s 'Full Throttle' features for a realistic experience. AccuMate® couplers are licensed from AccuRail, Inc.

Using this ATLAS N Scale EMD SD50 locomotive is a breeze. First, make sure your DCC system is set up correctly. If you're using DCC operation, you can easily program it according to your needs with the supported programming modes. When it comes to sound, just select your favorite horn, bell, and other sound effects. For installation, you can add the separate plow and winterization hatch as you like. During operation, keep an eye on the speed. The slower - speed motor is designed for closer - to - scale speeds, so don't try to run it too fast. As for maintenance, regularly clean the blackened wheels to ensure smooth running. Also, check the AccuMate® magnetic knuckle couplers for any signs of wear. If you're using the DCC and sound features, make sure to keep the system updated to enjoy all the functions. And remember, pictures might show a different road number, but the great features remain the same!
