Locomotive Jersey: UP No. 4014 "Big Boy"

Built to conquer mountains and haul the heaviest freight trains across the American West, Union Pacific Big Boy No. 4014 stands as one of the most powerful steam locomotives ever built. Originally completed in 1941, the legendary 4-8-8-4 was engineered to master the demanding grades of the Wasatch Mountains, where immense strength and unwavering reliability were essential. Today, after an extraordinary restoration, No. 4014 once again thunders across the rails, introducing new generations to the unmatched spectacle of mainline steam.

This jersey celebrates the largest operating steam locomotive in the world—a symbol of American innovation, industrial might, and the golden age of railroading. Designed for railfans, historians, and anyone inspired by legendary machines, it combines classic baseball jersey styling with details that honor one of rail history's greatest engineering achievements.

Whether you're chasing excursions, visiting railroad museums, or simply sharing your passion for trains, this jersey is a tribute to the locomotive that continues to captivate audiences wherever it travels.

Built to move mountains. Made to be worn. Honor the legend of Big Boy 4014.
