Union Pacific "Big Boy" 4014

Southern California Chapter
Railway and Locomotive Historical Society


 

Detail Pictures





Donated by the Union Pacific Railroad in January, 1962, locomotive 4014 is a proud  addition to the Southern California Chapter's impressive display of locomotives.  Number 4014 is a 4-8-8-4 type.  It is the heaviest single expansion steam locomotive ever built, weighing over one million pounds in working order. The 4014 is articulated because of its great length, that is, the forward pony trucks and drive wheels swivel independently of the boiler and rear drivers when rounding curves.  "Big Boy" was designed for heavy, fast freight trains and was used between Ogden, Utah and Cheyenne, Wyoming.  It was retired in 1959 after only 18 years of service; a comparatively short life for a steam locomotive.
