Wyoming’s Big Boy Rides The West Again & You Can Go

All aboard for the Union Pacific Westward Bound Tour. 

Roll through Wyoming and other Western states with one of the biggest steam engines ever built pulling the train.

Union Pacific's legendary Big Boy No. 4014, the world’s largest operating steam locomotive built to conquer mountains, will make 19 whistle-stops in five states this summer during its 2024 Westward Bound Tour from Wyoming to California.

See this mighty steam locomotive will be on public display for two days each in Roseville, California, July 12-13, and Ogden, Utah, July 20-21.

Big Boy will leave its home base in Cheyenne, Wyoming.

On June 30 Big Boy will begin traveling across Wyoming, Utah, Nevada, California and Idaho.

Display days in Roseville and Ogden offer an up-close look at the 1.1-million-pound marvel along with the "Experience the Union Pacific" rail car, a captivating walk-through exhibition that provides a unique glimpse into the rich history of railroading.

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

During the tour, the Union Pacific Museum will host a special, sold-out passenger trip from Roseville to Sparks, Nevada.

The unique experience is the annual gala fundraiser for the nonprofit organization and provides a rare opportunity to travel on this historic heritage equipment.

More information on this sold-out excursion is available at UPtraintix.org.

Big Boy No. 4014 will be at the listed public whistle-stop locations, as well as during display hours in Roseville, California, and Ogden, Utah.

There is no public access to the Big Boy outside these listed stops.
