Union Pacific Receives Texas Environmental Excellence Award

Railroad Pioneered Genset Technology for Industry

Spring, Texas, May 04, 2011 – The Texas Commission on Environmental Quality (TCEQ) today presented Union Pacific Railroad with an Environmental Excellence Award for developing some of the most environmentally friendly locomotives, which are now operating in the Lone Star State.

The TCEQ honored the state's most outstanding pollution prevention projects during a presentation in Austin. Union Pacific's Genset switcher locomotives were recognized in the technical and technology category. Genset locomotives reduce emissions of particulate matter and oxides of nitrogen by 80 to 90 percent compared to older switching locomotives. In addition, Gensets use 37 percent less fuel and have an equal reduction in carbon dioxide emissions.

Union Pacific pioneered the Genset locomotive and operates 98 Gensets in rail yards located in Texas. Instead of operating with one large engine, three 667-horsepower ultra-low emitting engines power the Genset locomotives. Gensets use a single engine for smaller jobs and activate the other two engines only when additional power is needed.

"We are honored to accept the Environmental Excellence Award, recognizing the contribution of Union Pacific's Genset locomotives to improving the air quality in Texas," said Gregory Workman, Union Pacific vice president - Operations for the Southern Region. "The Gensets are just one example of how our employees are using innovative technology to help Union Pacific protect the environment in the communities we serve."

Union Pacific's fleet of 165 Gensets represents approximately half of all Gensets operating worldwide. In addition, Union Pacific employs a comprehensive fuel-efficiency strategy for its more than 8,000 locomotives across its 32,000-mile rail network, and implements an environmental management process that includes systems and employee training to help reduce the company's environmental impact.
