STB Halts Union Pacific-Norfolk Southern Review, Seeks More Data

The Surface Transportation Board paused its review of the Union Pacific and Norfolk Southern merger application, accepting the resubmitted filing but demanding substantial additional documentation by July 27. The Board found the revised application barely meets completeness standards, lacking sufficient detail on competitive impacts, public benefits, market share effects and downstream consequences. The STB's information requests delay environmental review until after the supplemental data arrives. The Board indicated it may grant a 30-day extension if requested, pushing potential deal closure to late fall 2027 at the earliest. The STB expressed concern that Committed Gateway Pricing—a central component of the merger proposal—covers only limited traffic categories while excluding intermodal and automotive shipments. The Board signaled it views the review as discovery-driven rather than application-centric, committing to thorough examination of merger implications.
