This was further magnified in the 1970s * Packaging securely holds the model for safe storage when the fuel crisis impacted general transportation as well as the * Minimum radius: 22" railroad industry. In May of 1981, EMD unveiled the new SD50 which would feature an updated version of the V16 645 from the venerable SD40-2, upgraded to 3,500 hp at 900rpm. The SD50 had a longer frame and much longer long hood than its predecessors. Other improvements came from moving the dynamic brake resistors for the dynamic brake grid from the traditional location above the prime mover to a cooler temperature location in front of the engine compartment air intakes, closer to the electrical switchgear. This, in turn, separated them from other systems, resulting in simplified maintenance for both the prime mover as well as the electrical system. A grand total of 426 units were produced when production ceased in Feb of 1986. $269.99 w/o SOUND | $369.99 w/ SOUND These items are subject to Horizon's MAP policy VISIT Your Local Retailer Orders Due: 07.26.24 CLICK Athearn.com ETA: NOVEMBER 2025 CALL 1.800.338.4639
