Awakened from its 48-year slumber, the world’s largest steam locomotive — known affectionately as the “Big Boy #4018” — has rolled its way to a new home. The 1.2 million-pound train engine, built in 1942, is one of eight left in the world and the star of the MUSEUM OF THE AMERICAN RAILROAD’s extensive collection that has been in limbo since 2011, when the not-for-profit museum began moving from its site in Dallas’ Fair Park to a much larger facility in Frisco, Texas. With the epic, 55-mile journey of the entire 4,250-ton collection now complete, the museum is beginning to reopen. Among its 42 pieces of train cars and locomotives are “the finest collection of Pullman sleeping cars in the United States,” says Bob LaPrelle, president and CEO of the museum. With structures and artifacts dating to 1890, the menagerie of railroad paraphernalia transcends old-fashioned transportation history. “The story we tell is really the story of our nation and its commerce and industrialization,” LaPrelle explains. “You can’t separate the history of the U.S. from the history of the railroads.”,
