Big Boy No.4014
The American Locomotive Company 4000-class 4-8-8-4 locomotive, popularly named Big Boy, is an articulated, coal or oil-fired, steam locomotive manufactured between 1941 and 1944 and operated by the Union Pacific Railroad in revenue service until 1959.
The Big Boy fleet of twenty five locomotives was initially built to haul freight over the Wasatch mountains between Ogden, Utah and Green River, Wyoming. In the late 1940’s, they were reassigned to Cheyenne, Wyoming, where they hauled freight over Sherman Hill to Laramie, Wyoming. They were the only locomotives to use a 4-8-8-4 wheel arrangement consisting of a four-wheel leading truck for stability entering curves, two sets of eight driving wheels and a four-wheel trailing truck to support the large firebox.
According to a Union Pacific executive, this 4000-class 4-8-8-4 series originally was to have been called the "Wasatch". One day while one of the engines was being built, an unknown worker scrawled "Big Boy" in chalk on its front. With that, the legendary name was born and has stuck ever since.[2]
Only two preserved Big Boys remain in operable or close-to-operable condition: the 4012 and the 4014. Six other Big Boys have been preserved elsewhere in various museums.
