SALT LAKE CITY — The world's largest steam engine will spend a little more time in its old home than initially advertised.
Union Pacific on Tuesday unveiled dozens of more stops that the Big Boy No. 4014 will make across the West between March 29 and April 24, including three extra stops in Utah.
The historic 133-foot-long, 1.1-million-pound locomotive will make stops in Morgan and Salt Lake City on April 2, as it moves west toward California. It will pass by Morgan again on April 20, following its two-day display in Ogden, which was announced last month.
All of the Utah stops are part of a transcontinental tour that Union Pacific is putting on in celebration of the 250th anniversary of the nation's founding. It's the first time that the train will make a cross-country tour, and it will be by "No. 1776 — America250" and another commemorative locomotive.
Big Boy No. 4014 is the only remaining Big Boy locomotive that remains in operation of the 25 that were built in the 1940s to help haul heavy freight loads through the Wasatch Mountains. Seven others are still in existence but are retired.
It last made a stop in Utah during a Western tour in 2024. Spectators are urged to remain at least 25 feet from all railroad tracks, including drones, when the train rolls through the state in April. Drivers are also urged not to pace the train for a better view.
