PROTOTYPE SPECIFIC INFORMATION * With Sound version features Econami Sound by Soundtraxx The SD50 was produced in response to increasingly tough * All-wheel drive with precision gears for smooth and quiet competition from GE Transportation Systems, whose Dash 7 operation line was proving quite successful with railroads. While EMD's * All-wheel electrical pickup SD40-2 was a reliable and trusted product, GE's line included * 5-pole motor with flywheels and multi-link drivetrain for trouble- locomotives up to 3,600 hp (2,685 kW) with more modern tech- free operation nology, as well as very competitive finance and maintenance * Wheels with RP25 contours operate on all popular brands of track deals. EMD responded throughout the SD50 program by offer- * Window packaging for easy viewing ing discounts on large orders. * Interior plastic blister safely holds the model for convenient storage GM-EMD had previously produced 3,600 hp (2,685 kW) lo- * Minimum radius: 18" comotives, the SD45 and later SD45-2, but these used huge, * Recommended radius: 22" 20-cylinder engines with high fuel consumption, and had reli- ability problems when first introduced. Demand for the 45 series dropped sharply after the 1970s fuel crisis. The SD50 used an updated version of the V16 645 used in the SD40-2, uprated to 3,500 hp (2,600 kW)- and later 3,600 hp (2,685 kW) - at 950 rpm from 3,000 hp (2,240 kW) at 900 rpm. This proved to be a step too far. Due to this, many SD50s were rebuilt and/or derated to 3000hp, and gave reliable service for many years. Rebuilt versions can still be found in service today.
