UNP and Rocky Mountain Steel have finalized a new agreement.

Union Pacific Railroad and Rocky Mountain Steel Mills have signed a seven-year contract for domestic steel rail production, reinforcing Union Pacific's commitment to sourcing most of its rail from U.S. manufacturers. Rocky Mountain Steel, the only dedicated rail mill in the U.S., is set to begin operations at a new, advanced rail mill in Pueblo, Colorado, backed by a $1 billion investment. This partnership, which dates back to the 1890s, aims to enhance American manufacturing and support domestic job growth, while the new long rail mill will improve efficiency and safety for major railroads with its innovative production capabilities.
