Union Pacific Signs 7-Year Steel Rail Deal with Rocky Mountain

What happened

Union Pacific announced a seven-year steel rail supply agreement with Rocky Mountain Steel Mills, the only remaining dedicated steel rail production facility in the United States, located in Pueblo, Colorado. The contract extends a partnership dating back to the early 1890s and commits Union Pacific to sourcing the majority of its rail from domestic manufacturers. As part of the agreement, Union Pacific withdrew a lawsuit filed in Nebraska that alleged Rocky Mountain Steel had broken long-term supply deals by refusing to ship rail unless the railroad agreed to a 61% price increase. Rocky Mountain Steel had argued the price increase was a necessary adjustment to market pricing. The settlement resolves all pending legal disputes between the two companies.

Why it matters

The agreement secures a domestic supply of critical infrastructure material as Union Pacific pursues a proposed merger with Norfolk Southern to create the nation's first transcontinental railroad. CEO Jim Vena stated the partnership becomes more important as the company seeks to expand its network and strengthen domestic manufacturing. Reliable access to U.S.-made steel rail supports operational safety and service reliability. The resolution of the pricing dispute removes legal uncertainty and strengthens a long-standing supplier relationship that dates back more than 130 years. Rocky Mountain Steel is preparing to open a new $1 billion long-rail mill later this year that will produce 328-foot rails requiring 80% fewer welds than standard 80-foot sections, potentially improving track safety and operational efficiency.

Bigger picture

Rocky Mountain Steel's Pueblo facility is the only dedicated steel rail production mill in the United States, making it a critical component of domestic rail infrastructure. The mill produces steel using United Steelworkers union members and is backed by more than $1 billion in investment. The new long-rail mill will be powered by an 1,800-acre solar farm, positioning it as the world's largest solar-powered steel mill. Atlas Holdings completed its purchase of the Pueblo mill in August 2025 and formed Orion Steel Companies to oversee the facility along with mills in Oregon and Canadian assets. Union Pacific's initial merger application with Norfolk Southern was rejected by the Surface Transportation Board in January due to insufficient information, and the companies are working to submit a revised application. The Board indicated the rejection should not be interpreted as a final assessment of the merger.

What to watch

Progress on Union Pacific's revised merger application with Norfolk Southern and any regulatory guidance from the Surface Transportation Board. The opening and production ramp-up of Rocky Mountain Steel's new long-rail mill later this year, which is expected to produce 100-meter rails. The outcome of a similar lawsuit filed by BNSF Railway against Rocky Mountain Steel in Texas, which remains pending.
