en.Wedoany.com Reported - Union Pacific Railroad has recently signed a new seven-year contract with Rocky Mountain Steel in Pueblo, Colorado, for steel rail production. This steel rail supply contract will enable Union Pacific to procure the majority of its rail requirements from this U.S. manufacturer, thereby strengthening the domestic supply chain.

According to Union Pacific, Rocky Mountain Steel is the sole dedicated steel rail production facility in the United States and one of the largest steel product producers in North America. Since the early 1890s, Union Pacific, as a Class I railroad, has been using rails from Rocky Mountain Steel. The new contract not only continues this longstanding partnership but also resolves previous legal disputes between the two parties.

Rocky Mountain Steel plans to commence operations at its new long rail rolling mill in Pueblo later this year. Union Pacific officials stated that the new facility will produce 328-foot-long rails. Compared to standard 80-foot rails, the longer rails require 80% fewer welds, which helps improve track safety and reliability.

Doug Matthews, CEO of Orion Steel, said, "This rolling mill is a vital part of America's steel transportation infrastructure, and its continued existence demonstrates that our nation provides the highest quality products for railroads, both large and small." Orion Steel acquired Rocky Mountain Steel in August 2025. The signing of this steel rail supply contract is expected to boost the domestic steel industry in the United States and support the modernization of the rail transportation network.
