Union Pacific Makes Track Improvements to Its Wyoming East-West Line

The Railroad is Investing $12 Million on Track Maintenance between Cheyenne and near Hanna, Wyo.

Omaha, Neb., July 30, 2008 – Union Pacific Railroad is investing $12 million this year on track improvements between Cheyenne and Hanna, Wyo.

When the project is complete, crews will have removed and installed 97,000 ties, spread 74,000 tons of rock ballast to ensure a stable roadbed and replaced the road surfaces at 36 crossings.  Work will begin on these projects August 1 and is scheduled to be completed by October 1.

During 2008, Union Pacific plans to invest a total of $3.1 billion for capital projects that include $1.6 billion earmarked to maintain and strengthen the track infrastructure across its more than 32,300-mile system.  This extensive investment in the railroad's track helps ensure Union Pacific has the capability to offer quality, safe and cost-effective service to meet our customers' current and future transportation needs. Following track improvement projects, communities benefit from smoother road crossing surfaces and trains do not occupy crossings as long because they can operate more efficiently.
