PHOTOS: Union Pacific’s Big Boy No. 4014
The world’s largest and only operating steam locomotive, the Union Pacific Big Boy No 4014, passed through the area Sunday morning on its massive cross-country tour. Built in 1941 to conquer steep mountain grades, this 1.2-million-pound behemoth passed directly through parts of western Pennsylvania on its coast-to-coast trip to celebrate the nation’s 250th birthday. The tour includes a Fourth of July celebration in Philadelphia, major display events in eight cities and more than 50 whistle-stops in 10 states, including stops for the first time in Indiana, Ohio, New York and Pennsylvania.
