Dow Jones Description

Omaha, Neb., April 17, 2006 Building on its reputation as having the most environmentally friendly locomotive fleet in the United States, Union Pacific today announced it is testing technologies to reduce diesel engine emissions in older railroad locomotives. Through collaboration with staff at the National Vehicle and Fuel Emissions Laboratory of the U.S. Environmental Protection Agency (EPA) from Ann Arbor, Mich., Union Pacific is providing a 3,800-horsepower SD60M locomotive built in January 1992, to serve as the first freight locomotive in North America to be equipped with a set of oxidation catalyst or "oxicat" devices manufactured by the MIRATECH Corporation of Tulsa, Okla. These devices serve as flow-through catalytic converters. As the diesel engine's exhaust flows through these converters, microscopic particles known as "particulate matter" generated by the diesel combustion process will be converted into water and carbon dioxide. In a similar experiment, a 1,500-horsepower yard switching locomotive built in November 1982, also provided by Union Pacific, will be retrofitted with a diesel particulate filter or "DPF." The DPF initiative is the result of a four-year program, funded in part by Union Pacific, to assess clean-engine technologies for locomotive applications. The DPF acts as a filter that uses high-temperature silicon carbide blocks to trap particulate matter in the exhaust. ...
