MTH ELECTRIC TRAINS

Introduced in the mid-1980s, the SD60 and its four-axle sister, the GP60, were the first EMD diesels to incorporate computer technology and onboard diagnostics to aid the engineer. Under the hood was a new 16-cylinder model 710 prime mover rated at 3800 horsepower. While the SD60 looked almost identical to the SD50 introduced just four years earlier, under the hood virtually everything had changed. Problems with the SD50 had led EMD to a total redesign that introduced the firm's third generation of diesel locomotives.

The earlier SD50's model 645 prime mover was working so close to its limitations that the motor required a major overhaul every two years - twice as often as the motor in the previous SD-40 and SD40-2 locomotives. Responding to customer complaints, EMD developed the stronger, more reliable model 710 prime mover introduced in the SD60 series.

Like all RailKing Scale diesels, the SD60 sports prototypical 1:48 scale dimensions. Operators looking to pair up a powered unit for a lash-up configuration will find no better locomotives for mainline work.
