EMD SD50
(ESU Sound and DCC)

Kansas City Southern  No. 711

Limited Edition!

As demand for higher-horsepower units and better fuel economy continued to grow in the late 1970s, EMD began testing a new six-axle model in 1979, which entered production as the SD50 in 1981.

Like the prototype, this locomotive is a great addition to your railroad's fleet of heavy diesel road units.
