Page 21 - BNSF 2012 Corporate Profile

Reducing carbon emissions in our business is largely about locomotive efficiency. Since the beginning
of 2000, BNSF has acquired about 3,000 new locomotives, making its fleet one of the industry’s newest
and most fuel-efficient. Since locomotives have a life span of 30+ years, BNSF continuously looks at its
entire fleet of locomotives, retrofitting and remanufacturing them as needed to be more fuel-efficient and
cleaner-burning.
BNSF also has 86 ultra-low emission switch locomotives that reduce nitrogen oxides and particulate
matter emissions by 80 to 90 percent and improve fuel efficiency by 25 percent compared to standard
switch engines.
