Spring, Texas, January 24, 2012- Union Pacific Railroad will continue improving the transportation infrastructure in San Antonio by investing $4 million in one of two rail lines that parallel Frio City Road. The comprehensive project will help trains move more efficiently through the west side of the city.

A new automated system will allow crews to move trains onto separate tracks without leaving their locomotive cabs to manually align track switches. Union Pacific will also add a section of track that connects the rail line from Brazos Street to Cumberland Boulevard.

The project includes the installation of 2,350 feet of rail, 1,000 railroad ties and four track switches. More than a thousand tons of rock ballast will be used to help provide a more stable roadbed. In addition, crews will renew the South Brazos Street and Pendleton Avenue grade crossings. The work is scheduled to be completed by July of 2012.

"I am pleased to see Union Pacific make this significant investment to enhance its operations in San Antonio," said District 5 Council Member David Medina. "These improvements will help decrease wait times for drivers and benefit the entire community."

Union Pacific plans to invest $3.6 billion in capital during 2012, which supports America's current and future freight transportation needs and enhances the safety and efficiency of the railroad's 32,000-mile network.  These investment projects are examples of Union Pacific's continuing efforts to improve transportation infrastructure and support its customers through strategic investments.

According to the Association of American Railroads, America's largest railroads keep pace with the top nine states in terms of highway spending, and they do it with private, not taxpayer, money. In 2010, capital spending by Class I railroads totaled $9.8 billion. All told, freight rail companies have invested $480 billion to maintain and modernize the national rail network since 1980.

Improved and additional rail capacity benefits everyone. It allows freight rail service to grow, helping to build a cleaner environment. Union Pacific can move one ton of freight nearly 500 miles on a single gallon of diesel fuel, and, according to the U.S. Environmental Protection Agency, freight trains are nearly four times more fuel efficient than trucks. Motorists also benefit from reduced congestion on highways as a single Union Pacific train can remove up to 300 trucks off our roads.
