Renewed Partnership Between Iconic Railroad and Only Remaining Dedicated Steel Rail Supplier in the United States
Contract Represents a Significant Commitment to Domestic Steel Production, the United Steelworkers and the Historic Steel Town of Pueblo, Colorado
OMAHA, Neb., April 15, 2026–(BUSINESS WIRE)–Union Pacific Railroad (NYSE: UNP) and Rocky Mountain Steel Mills (“Rocky Mountain Steel”) announced today they have reached a new, seven-year contract for the domestic production of steel rails, underscoring Union Pacific’s clear commitment to buying the majority of its rail from a United States manufacturer. Rocky Mountain Steel, located in Pueblo, Colorado, is the only remaining dedicated rail production facility in the United States and one of the largest producers of steel products in North America. Steel made for Union Pacific, and all Rocky Mountain Steel customers is produced by members of the United Steelworkers (USW).
Union Pacific has been using steel rail from the mill at Rocky Mountain Steel since the early 1890s. This renewed commitment by Union Pacific underscores their commitment to Rocky Mountain Steel, now operating under new ownership and management, as well as the skilled workers of the USW and the historic steel community in Pueblo. The agreement ends any pending legal disputes between the companies, as Union Pacific has withdrawn its previously filed lawsuit in Nebraska.
Rocky Mountain Steel expects to begin operations this year at a new, state-of-the-art long rail mill, constructed with a more than $1 billion investment in domestic steel production. The new mill will ensure Pueblo will remain the only dedicated steel rail mill in the United States, operating one of the most advanced rail production lines in the world.
“We appreciate the longstanding relationship with Rocky Mountain Steel, its dedicated workforce and their collective commitment to domestic steel manufacturing. The new long-rail mill is a significant step forward in American manufacturing that supports Union Pacific’s focus on delivering safe, reliable service for our customers,” said Jim Vena, CEO of Union Pacific. “As Union Pacific pursues its merger with Norfolk Southern to create the nation’s first transcontinental railroad, our ability to partner with Rocky Mountain Steel becomes even more critical as our merger is positioned to strengthen the nation’s manufacturing core as well as domestic job growth.”
“The new contract reinforces the one-of-a-kind partnership between Union Pacific Railroad and Rocky Mountain Steel, a relationship that traces its roots back to the 1890’s and has been benefiting American workers every day since,” said Doug Matthews, CEO of Orion Steel, the parent company of Rocky Mountain Steel Mills. “This mill is an essential part of America’s steel transportation infrastructure, and its continued existence shows that our nation offers railroads large and small the very best product, made by the very best steelmakers in the world. I thank Union Pacific leadership for making that case crystal clear via this new long-term contract.”
