# Union Pacific's Big Boy No. 4014 Embarks on First-Ever Coast-to-Coast Steam Tour

Union Pacific will join the nation in celebrating 250 years of American independence and innovation this year with its first-ever coast-to-coast steam tour led by the legendary Big Boy No. 4014.

The first leg of the tour starts Sunday, March 29, with the Big Boy and several historical passenger cars from Union Pacific’s Heritage Fleet traveling west to California from Cheyenne, Wyoming—the steam locomotive’s homebase. The first leg of the tour ends Friday, April 24, back in Cheyenne.

Two major public display days are scheduled:

- Friday and Saturday, April 10-11: Roseville, California

- Saturday and Sunday, April 18-19: Ogden, Utah

A daily schedule with additional stops, along with a map of the route, will be released closer to the tour’s launch.

Note: There will not be any passenger excursions offered on this western leg of the tour.

## About the Union Pacific Big Boy

The Union Pacific Big Boy is a type of simple articulated 4-8-8-4 steam locomotive manufactured by the American Locomotive Company (ALCO) between 1941 and 1944. It was operated by the Union Pacific Railroad in revenue service until 1962.

The 25 Big Boy locomotives were built to haul heavy freight over the challenging Wasatch Range between Ogden, Utah, and Green River, Wyoming. In the late 1940s, they were reassigned to Cheyenne, Wyoming, where they continued hauling freight over Sherman Hill to Laramie, Wyoming.

Today, eight Big Boys survive, with most on static display at museums across the United States. One of them, No. 4014, was reacquired by Union Pacific and meticulously restored to full operating condition by 2019 in time to celebrate the 150th anniversary of the first transcontinental railroad.
