Union Pacific’s Big Boy No. 4014 drew crowds again in Utah this month as the restored steam locomotive rolled past the Wasatch Mountains on its 2026 coast-to-coast tour. (up.com, up.com) Union Pacific says the western leg of the tour began March 29 in Cheyenne, Wyoming, and runs through April 24, with public display days in Ogden on April 18-19. The railroad scheduled 27 whistle-stops and four public display days across four western states. (up.com, up.com) The Utah stop was not incidental. Big Boy locomotives were built for Union Pacific to haul heavy freight over the Wasatch grade, and No. 4014 was assigned to that territory after its 1941 delivery. (up.com, wikipedia.org) That history is part of why modern videos of No. 4014 in northern Utah travel so widely online. Union Pacific is running the 2026 trip as its first coast-to-coast steam tour, tying the excursion to the nation’s 250th anniversary observance. (up.com, up.com) No. 4014 is the only operational Big Boy and the world’s largest operating steam locomotive, according to Union Pacific. The railroad says the engine was restored in 2019 after a multi-year project tied to the 150th anniversary of the transcontinental railroad’s completion. (up.com, up.com) Union Pacific’s heritage page lists the locomotive at 132 feet long and about 1.2 million pounds, with an articulated frame that lets the engine bend through curves despite its size. In railroad terms, its 4-8-8-4 wheel arrangement means one leading truck, two sets of eight driving wheels, and a four-wheel trailing truck. (up.com) The railroad’s tracker showed No. 4014 moving near West Elko, Nevada, on April 15, indicating the westbound and return routing was still active days before the Ogden public display weekend. Local Utah coverage also flagged the April 18-19 Ogden appearance as one of the main public viewing dates on the spring run. (up.com, ksl.com, standard.net) For railfans, the Utah footage lands at the point where No. 4014’s original job and current role meet: a 1941 freight engine built for the Wasatch route, now back on that landscape as a traveling museum piece under steam.
