Due to the increase of better highways in the 1950’s the trucking industry was beginning to siphon off time sensitive traffic from the railroads. Consequently, in the late 1950’s the Union Pacific began seeking ways to increase the horsepower of their locomotives in order to help improve train speeds without having to add more locomotives to their trains. One method to achieve these goals was to mount two complete prime movers on one chassis. UP asked the 3 major locomotive builders at that time to submit proposals using this concept. In response, General Electric created their 5,000-horsepower U50 model, a design which utilized two 2500-horsepower prime movers. Starting in September 1963, UP purchased a total of 23 U50’s, all of which were retired by the mid-1970’s.

There were few changes made to these units during their time on the UP but one, #41, suffered from a significant fire and had to be repainted. It was the only one to receive UP’s 1970’s era slogan, “We Can Handle It.”

PROTOTYPE SPECIFIC INFORMATION

In 1963, the diesel horsepower race had just reached 2,500 horsepower and the only way to get 5,000 horsepower was by putting two diesel engine and generator sets onto one chassis. Given the wheel slip and traction motor technology at the time, eight traction motors and powered axles were needed to convert the horsepower into pulling power. EMD had already produced the DD35, two cab less GP35s on one chassis. General Electric’s answer was to do the same with two U25Bs, which created the U50.

The U50 was 83 feet 6 inches long and towered over most contemporary locomotives at 15 feet 10 inches tall. They weighed in at 559,620 pounds and produced 139,175 pounds of starting tractive effort. Inside the hood were two FDL-16 diesel engines, each with a generator, full radiator, and dynamic brake setup. The U50 rode on two sets of two-axle AAR-B trucks mounted on a span bolster. The trucks were recycled from the scrapped gas turbines. Up front was a tall, blunt nose cab without a front walkway, which gave the U50 its unique appearance.
