Safety and the Environmentparticulate matter and other pollutants. With more than twothirdsof its road locomotives certifi ed under the existing EPAtier standards, UP owns the cleanest fl eet in the nation. Furtherimprovements are on the horizon as the Company works withmanufacturers to fi eld-test new, high-horsepower locomotives thatsurpass the EPA’s most stringent standards. UP is also retrofi ttingolder locomotives with new emission-reduction equipment.<strong>Union</strong> Pacifi c has a comprehensive waste reduction andrecycling program that touches nearly every part of the Company.Concerted efforts are made to address high-volume items suchas wooden track ties and used oil. When possible, wooden trackties are refurbished for use elsewhere on the UP system or sold tocontractors. UP is also installing more concrete ties, which requirelower maintenance and generate less waste than wooden ties.UP helped test and develop an ultra low-emissions switchlocomotive, the “Genset Switcher”. These units utilize “off-road”truck–style diesel engines that are projected to reduce emissionsof nitrogen oxide by 80 percent and particulate matter by 90percent. Additionally, these engines use as much as 37 percentless fuel compared to current older switching locomotives. UP’scommitment to, and operation of, the Genset resulted in thecompany earning the <strong>2008</strong> CALSTART Blue Sky Merit Award. Thisaward recognizes outstanding contributions to clean air, energyeffi ciency and a cleaner transportation industry overall. <strong>Union</strong>Pacifi c also partnered with the EPA on one-of-a-kind fi eld testingto reduce emissions on older road and switch locomotives.Did you know...?• Trains are almost four times more fueleffi cient than trucks on a ton-mile basis.• If just 10 percent of the freight moved byhighway were diverted to rail, the nationcould save as much as 1 billion gallons offuel annually.• Fuel effi ciency for U.S. railroads hasincreased by 86 percent since 1980.• One double-stack train can take up to300 trucks off congested highways.9
