Progress Rail and Wabtec Corporation reached a settlement on 26 February 2026 in the case Progress Rail v. Wabtec, ending antitrust litigation between the two US locomotive manufacturers. The agreement contains no admission of liability by either party.
Progress Rail, a wholly owned subsidiary of Caterpillar, and Wabtec both supply long-haul freight locomotives and cab components to Class I railroads and other customers in North America. Their portfolios include Tier IV long-haul freight locomotives compliant with US emissions standards.
Both companies remain active suppliers of freight locomotives, components and related services in the North American market.
