The steepest grade was the eastbound climb on the Echo Canyon line through the Wahsatch Mountains just east of Ogden, Utah. Forty 4-6-6-4 Challenger locomotives were acquired in 1936 and 1937 to move fast freight over the grades in Utah and Wyoming. They were rated at 4,290 tons across Wyoming, but were limited to 3,100 tons eastbound through Echo Canyon. \u003c\/p\u003e\u003cp style=\"font-size: 13.600000381469727px;\"\u003eUnion Pacific wanted something that could make the same speeds as the Challengers but could carry the entire 4,290-ton train over the Wahsatch Mountains without a helper. The easiest solution was to scale up the successful Challenger design by adding another pair of drivers to each half of the locomotive thus making a 4-8-8-4. \u003c\/p\u003e\u003cp style=\"font-size: 13.600000381469727px;\"\u003eIn 1941 UP placed an order for twenty 4-8-8-4’s, numbered 4000 through 4019, with the American Locomotive Works. Each engine cost $265,174. According to legend an unidentified machinist at the ALCO plant is responsible for the name “Big Boy”, having scrawled the name in chalk on a partially completed locomotive. \u003c\/p\u003e\u003cp style=\"font-size: 13.600000381469727px;\"\u003eThe Big Boys were exactly what the railroad wanted. They were coal burners with 68-inch drivers, 135,375 pounds of tractive effort and 6,000 horsepower. They started service on the line from Ogden to Green River, Wyoming and their operating range soon increased to cover the line all the way to Cheyenne. \u003c\/p\u003e\u003cp style=\"font-size: 13.600000381469727px;\"\u003eTraffic during WWII resulted in five more Big Boys, numbered 4020 through 4024, being built in 1944. These versions were slightly heavier than the original order due to wartime materials restrictions.Despite the influx of diesel locomotives following WWII, the Big Boys and Challengers remained the prime power on the Overland Route. They also saw service as helpers, leading gas turbines and diesels over Sherman Hill. They remained active through the 1950’s and weren’t retired until the early 1960’s. By then the first twenty units had been run well over one million miles. \u003c\/p\u003e\u003cp style=\"font-size: 13.600000381469727px;\"\u003e\u003c\/p\u003e\u003cp style=\"font-size: 13.600000381469727px;\"\u003eUP #4014 PROMONTORY FEATURES: \u003c\/p\u003e\u003cp style=\"font-size: 13.600000381469727px;\"\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cspan style=\"font-size: 1em;\"\u003eGreat Race to Promontory version with oil tender from UP 3985 per prototype configuration \u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan style=\"font-size: 1em;\"\u003eReporting marks only on rear tender face per prototype 2019 configuration \u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan style=\"font-size: 1em;\"\u003eFreshly shopped shiny appearance \u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan style=\"font-size: 1em;\"\u003eCommemorative box \u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan style=\"font-size: 1em;\"\u003eChalk marking “Big Boy” factory applied to smoke box face, per prototype during summer 2019.

The locomotives were 132 feet long and weighed 1.2 million pounds. Because of their great length, the frames of the Big Boys were “hinged,” or articulated, to allow them to negotiate curves. They had a 4-8-8-4 wheel arrangement, which meant they had four wheels on the leading set of “pilot” wheels which guided the engine, eight drivers, another set of eight drivers, and four wheels following which supported the rear of the locomotive.
