Union Pacific 4014 Begins Coast-To-Coast Tour

Published: February 15, 2026

Union Pacific’s legendary 4-8-8-4 “Big Boy” No. 4014 is scheduled to return to the main line in a big way this spring, kicking off the railroad’s first-ever coast-to-coast steam tour as part of a broader celebration tied to America’s 250th anniversary in 2026. The opening chapter—known as the western leg—is set to begin Sunday, March 29, 2026, when the 4014 departs its home base in Cheyenne, Wyoming, with members of Union Pacific’s Heritage Fleet in tow, heading west toward California before looping back to Cheyenne.

A westbound kickoff from Cheyenne

According to Union Pacific, the March 29 departure marks the start of a multi-stage national program that will ultimately reach far beyond the locomotive’s typical seasonal excursions. For the western leg, the railroad says Big Boy 4014 will pull a consist that includes historic passenger equipment from the company’s heritage collection—turning the move into a rolling museum exhibit as much as a rail journey.

Union Pacific has published the western-leg schedule on its official steam pages, noting that this first segment of the coast-to-coast effort will run from March 29 through April 24, concluding back in Cheyenne.

Two headline display stops: Roseville and Ogden

While the route includes multiple towns and pacing opportunities, Union Pacific is spotlighting two major public display windows where fans can expect the most accessible viewing:

Roseville, California — April 10–11
Ogden, Utah — April 18–19

These display dates—announced by Union Pacific and echoed by rail-industry coverage—are likely to become the marquee moments of the western leg, drawing large crowds and making early planning essential for anyone hoping to attend.

The coast-to-coast picture

Union Pacific has been clear that the March–April western trip is only the beginning. The railroad says the eastern leg, anticipated to start later in spring 2026, is still being finalized and will be announced once details are set.

That means the “coast-to-coast” branding is very real—but also still unfolding. In practical terms, March 29 launches the first confirmed portion of a much larger initiative that will expand as additional routing and operating partners are locked in for the later legs.

A national celebration

Big Boy 4014’s modern-era excursions have already proven that a restored 1940s giant can still capture national attention. But Union Pacific’s framing of this tour is notably bigger than a typical seasonal outing: the railroad is explicitly tying the program to a nationwide commemoration of American independence and innovation during the country’s 250th year.

For Union Pacific, the tour doubles as a high-profile heritage initiative—one that blends public outreach, brand storytelling, and living industrial history. For railfans, it’s a chance to see not only the locomotive under steam, but also a curated slice of Union Pacific’s preserved passenger-era image rolling across major corridors.

Following the action: schedule pages, tracking, and alerts

Union Pacific is directing the public to its official steam schedule and related steam-program pages for the most reliable information, including timing notes and updates. The railroad also promotes its Steam Club for announcements and tour news as plans evolve—particularly relevant with the eastern leg still pending.

A key reminder for anyone planning a trip: steam schedules can change due to operational needs, weather, and network conditions. If you’re traveling any distance, treat the official schedule as the baseline—and check again close to your date.

What No. 4014 represents

Even among famous steam locomotives, Big Boy occupies rare air. Built for heavy freight across western grades, the type has become an icon of late-era steam engineering—huge boiler, massive articulated running gear, and the kind of presence that stops traffic even when it’s standing still. Union Pacific continues to describe No. 4014 as a symbol of American industrial capability and the “pinnacle” of steam-era technology.

Today, that engineering spectacle is paired with a modern operational reality: Big Boy runs on a living freight railroad. That combination—museum-scale artifact operating at speed on active main lines—is precisely why these tours draw such intense interest, and why Union Pacific’s safety messaging around the program remains so important.

Planning tips for 2026 viewers

If you’re hoping to catch the March–April western leg in person, a few practical strategies can make the experience better (and safer):

Aim for the official display days if you want the best chance at a stable viewing window (Roseville and Ogden are the headline examples).

Arrive early—big crowds are the norm, and parking near known viewing areas fills quickly.

Respect railroad property and local instructions. The best photo is never worth trespassing.

Stay flexible. Even with a published schedule, freight railroad operations can introduce delays or changes.
