Union Pacific’s famed Big Boy No. 4014, the world’s largest steam locomotive, will return to the rails in 2024 for a tour.

The tour is expected to reach all four corners of Union Pacific’s 23-state system with anticipated stops in Chicago; Dallas/Fort Worth; Houston; Nampa, Idaho; Portland, Oregon; Roseville, California; and Salt Lake City, Utah.

“As we move forward at Union Pacific, we remember where we came from; the Big Boy represents the history of Union Pacific and the United States,” said Union Pacific CEO Jim Vena. “When No. 4014 comes to town, we will celebrate with the communities where we operate, our employees and their families. Together, we will marvel at how far technology has brought us.”

No. 4014 is the only Big Boy in operation today, weighing 1.1 million pounds. It was restored in 2019 to celebrate the 150th anniversary of the transcontinental railroad’s completion.

Twenty-five Big Boy locomotives were built for Union Pacific to haul heavy freight during World War II, but only eight still exist. The other seven are on display around the United States.
