Train enthusiasts gather in Salt Lake City on Saturday, May 3, 2014, to get a look at Big Boy No. 4014, one of the world's largest steam locomotives. The train is being taken to Cheyenne, Wyo., for restoration. The locomotive is traveling 1,293 miles from Colton, Calif., for the ambitious project, which will take place at Union Pacific's Heritage Steam Fleet Operations headquarters. Big Boy No. 4014 was one of 25 Big Boys built for Union Pacific to carry freight on the transcontinental railroad. The locomotive's 17-year career ended in 1962, but Union Pacific is restoring it to return it to operating condition. After spending Saturday in Salt Lake City, the train will move to Ogden on Monday, where it will be on display at 2501 Wall Ave. from 9 a.m. to 4 p.m.
