Portland, Ore., January 24, 2012- Union Pacific Railroad employees in Oregon capped a decade of safety improvement in 2011 by achieving a 1.38 reportable injury rate, the best performance on record for the Portland Service Unit which includes Union Pacific operations across Oregon and Washington and into northern Idaho. Employees surpassed their previous best rate of 1.72, established in 2010, by 19.75 percent. From 2002-2011, Union Pacific employees across the company improved their reportable injury rate by 52 percent.

"Our Total Safety Culture initiative and identifying and standardizing best practices are important factors in our safety performance improvement," said Bob Grimaila, Union Pacific vice president - Safety, Security and Environment. "Employees participating in Total Safety Culture combine teamwork and best practices as we strive to achieve our ultimate goal of zero incidents or injuries."
