OMAHA, Neb. (AP) — Union Pacific will spend more than $1 billion to upgrade 600 of its old diesel locomotives over the next three years and make them more efficient, but regulators still want it to do more to cut pollution from its engines.
The move will accelerate the pace of upgrades UP already planned to make and help the Omaha, Nebraska-based railroad cut roughly 210,000 tons of carbon emissions each year -- the equivalent of taking 45,000 cars off the road. The railroad will go from modernizing 120 locomotives this year to modernizing 200 a year in each of the next three years.
“It’s really taking the older locomotive fleet and applying the latest and greatest to get one of the most fuel efficient locomotives we can have,” said Grace Olsen, who oversees locomotive engineering for Union Pacific.
The railroad estimates that this program will improve the fuel efficiency of these long-haul locomotives by up to 18% and help them produce peak power more reliably. To accomplish that, locomotive manufacturer Wabtec will strip down the locomotives, and spend eight weeks overhauling their engines and installing new software and electronic controls.
The improved power will let Union Pacific pull the same amount of freight with fewer locomotives. That, combined with the railroad's efforts to significantly boost the length of its trains, will allow Union Pacific to keep more of its fleet of 7,400 locomotives in storage. UP has already parked hundreds of locomotives as part of the operational changes it has made over the past several years.
Wabtec says this UP project is the biggest single investment in modernizing locomotives in railroad history although other major freight railroads are making similar improvements to their fleets. Earlier this year, Norfolk Southern announced plants to modernize 330 of its 3,200 locomotives over the next three years to give it more than 950 modernized locomotives by the end of 2025. UP will have 1,033 upgraded locomotives after its project.
