This is Wabtec’s fourth major modernization order from UP since 2018. Its third was in 2022 with the upgrade of 600 locomotives (525 AC4400s and AC6000s, as well as 75 Dash-9s); at that time, UP said more than 1,030 upgraded units would be delivered by 2025.
UP would not confirm to Railway Age the exact number of units to be modernized in its latest order, but the publication estimates approximately 670 since the railroad said it would have more than 1,700 modernized units in its fleet once all the work is completed.
The modernization work will take place at Wabtec’s U.S. facilities and is slated to deliver a 5%-plus reduction in fuel consumption, a 14% increase in tractive effort and an 80% improvement in reliability. According to the companies, each locomotive will receive the FDL Advantage (FDLA) engine upgrade “for enhanced fuel savings”; LOCOTROL® Expanded Architecture “to support safe, efficient operation of longer trains”; and the new Modular Control Architecture, which “unlocks the next-generation data, diagnostics and software capabilities.”
“We are committed to delivering the service we sold to our customers and one way we do that is having great American-made locomotives that can get the job done,” UP CEO Jim Vena said. “These redesigned locomotives will be just like new, providing the improved fuel efficiency and enhanced reliability that we need to grow with our customers and to win new business.”
“Our continued partnership with Union Pacific reflects a steady, forward-looking investment that positions the railroad and its customers for continued success,” commented Rafael Santana, President and CEO of Wabtec. “By enhancing our proven locomotive platforms with advanced propulsion, controls and diagnostics, this [modernization] program delivers substantial gains in performance, reliability and lifecycle value—allowing the railroad to unlock maximum efficiency and capability for its existing fleet.”
Separately, Canadian Pacific Kansas City and Norfolk Southern last month reported acquisitions of new Tier 4-compliant road units from Wabtec and Progress Rail.
