The Union Pacific Railroad has ordered 98 diesel-electric hybrid RailPower road switcher locomotives for use in Texas. The locomotives are estimated to provide fuel savings of 20% to 40% with reductions in NOx and particulates of about 80%. The locomotives are designed to reduce fuel usage in road and branchline switching operations where locomotives use up to three times the amount consumed by yard switchers. Union Pacific will apply its recent $81 million dollar award from the Texas Emmisions Reduction Plan towards the purchase of these locomotives.
