Scranton was once home to five major Class A railroads. In June 2026, it once again became the center of the railroad world.
Presented as part of the nationwide America 250 celebration, the historic reunion of Union Pacific Big Boy No. 4014, the world’s largest operating steam locomotive, and its sibling, Big Boy No. 4012, on permanent display at Steamtown National Historic Site, transformed the city into a destination for railroad enthusiasts, families, and history lovers from across Pennsylvania, throughout the United States, and around the world.
For the Lackawanna Heritage Valley Authority, the event represented one of the most significant heritage tourism experiences in the organization’s 35-year history.

Built in 1941 by the American Locomotive Company, Big Boy No. 4014 remains one of the greatest engineering achievements of the steam era. Designed to haul massive freight trains across the Wasatch Mountains, it became part of the transportation network that carried the coal, steel, machinery, and military supplies that fueled America’s industrial strength during World War II. More than eight decades later, it continues to stand as a symbol of American innovation, craftsmanship, and determination.
Its reunion with Big Boy No. 4012 at Steamtown carried special significance. Although the locomotives once worked side by side on Union Pacific’s transcontinental railroad, their appearance together in Scranton offered visitors a rare opportunity to experience one preserved for future generations and the other restored to operating condition. It was a powerful reminder that preservation and restoration work hand in hand to keep history alive.
Few moments better illustrated that connection than Big Boy’s crossing of historic Bridge 60 above the Lackawanna River Heritage Trail. As the giant locomotive thundered overhead, walkers and cyclists paused to watch a scene that connected the region’s railroad past with its recreational future. The former rail corridor below, now one of Pennsylvania’s premier multi-use trails, demonstrates how historic transportation infrastructure can continue serving communities in new and meaningful ways.
The event also underscored the value of heritage tourism. Visitors explored downtown Scranton, toured museums, walked the trail, stayed in local hotels, dined in area restaurants, and discovered the people and places that define northeastern Pennsylvania. Their visit extended well beyond the railroad tracks, providing an economic boost while introducing thousands of first-time visitors to the region’s rich industrial and cultural heritage.
“For more than two remarkable weeks, Scranton became a destination for people who wanted to experience history firsthand,” said LHVA Executive Director Joseph J. Corcoran. “The excitement surrounding the Big Boy reunion showed that America’s railroad heritage continues to capture the imagination of visitors from every generation. It also demonstrated the important role heritage tourism plays in strengthening local communities, supporting local businesses, and preserving the stories that define northeastern Pennsylvania. As we celebrate America’s 250th anniversary, there could be no better reminder that our history continues to shape our future.”
That may be Big Boy’s greatest legacy.
At a time when technology continues to reshape the way we live, a steam locomotive built more than 80 years ago brought together generations of visitors through a shared appreciation of American ingenuity and perseverance. It reminded us that our nation’s story is told not only through its founding documents and historic battlefields, but also through the railroads, factories, mines, and workers whose innovations helped build modern America.
Scranton demonstrated that preserving our industrial heritage is about more than remembering the past. It is about celebrating the ingenuity, resilience, and spirit that continue to define our communities today. As America marks its 250th anniversary, the reunion of Big Boy No. 4014 and No. 4012 served as a powerful reminder that history is not simply something we inherit. It is something we preserve, share, and pass forward to the generations that follow.
