PROTOTYPE SPECIFIC INFORMATION
The SD50 was produced in response to increasingly tough
competition from GE Transportation Systems, whose Dash 7
line was proving quite successful with railroads. While EMD’s
SD40-2 was a reliable and trusted product, GE’s line included
locomotives up to 3,600 hp (2,685 kW) with more modern technology, as well as very competitive finance and maintenance
deals. EMD responded throughout the SD50 program by offering discounts on large orders.
GM-EMD had previously produced 3,600 hp (2,685 kW) locomotives, the SD45 and later SD45-2, but these used huge,
20-cylinder engines with high fuel consumption, and had reliability 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.
