STB Sets Timeline For Merger Review
The U.S. Surface Transportation Board (STB) set a timeline for reviewing Union Pacific's (UP) acquisition of Norfolk Southern (NS), with a final decision expected by late 2027. Interested parties must state their intent by September 4, with comments, rebuttals, and a public hearing to follow. The merger, if approved, would create a 50,000-mile railroad network. The STB rejected UP's initial application in 2025 as incomplete.
