“When two great companies come together with a shared purpose, the benefits extend far beyond our businesses,” said Union Pacific chief executive officer Jim Vena. “Union Pacific and Rocky Mountain Steel Mills have a proud history of supporting American manufacturing, jobs and communities. As we look to the future, this renewed partnership will help strengthen our country's supply chain and demonstrates the importance of reliable rail transportation in keeping our economy moving.”

The delivery brings Union Pacific and Rocky Mountain’s relationship full circle — Union Pacific bought the first stick of rail out of the mill in 1882. In April, the two companies signed a seven-year rail supply agreement.

Rocky Mountain’s new long rail facility is an investment of approximately US$1.2 billion. It is one of the most advanced rail production lines in the world, making long rail in 100-m (328-foot) lengths. The product’s advantage is that it requires 80% fewer welds than standard 80-foot rail, improving track safety and reliability, Rocky Mountain said.

Doug Matthews, chief executive officer of Rocky Mountain parent Orion Steel, said the delivery marks the official start of operations at the rail facility and builds on the steelmaking heritage of Pueblo, Colo.

“Rocky Mountain Steel is proud to continue building this legacy with Union Pacific,” he said. “Our partnership with Union Pacific demonstrates what is possible when American companies work together to strengthen domestic supply chains and invest in the future.”
