Surface Transportation Board rejects rail merger application

Surface Transportation Board rejects rail merger application from Union Pacific (UP) and Norfolk Southern (NS) in a unanimous decision Friday afternoon, according to the Surface Transportation Board. The agency said the December 19 filing was incomplete, had to be rejected under the law, and was turned away without prejudice.

This is reported by the railway transport news portal Railway Supply.

In its announcement, the STB said the decision was limited to whether the December 19 submission met basic filing requirements. It added that the rejection should not be read as an indication of how the Board might evaluate any future revised application, a point also reflected in reporting by Railway Supply.

Why the UP NS merger application was rejected?

In the Board’s decision, the STB said the application did not include material required under the rules governing major railroad combinations. One omission involved the impact analyses required by 49 C.F.R. § 1180.7(b). The agency pointed to inconsistent claims about how the merged railroads would generate growth by diverting traffic from trucks and from other rail carriers.

The decision also said the filing did not include the complete merger agreement required by 49 C.F.R. § 1180.6(a)(7)(ii). Certain documents were missing or incomplete, and the STB treated that as another reason the application could not proceed as submitted.

Related control filings: Peoria and Pekin Union and St. Louis terminal

Two other business transactions included in the merger application were affected by the Board’s action. One involved an acquisition for control of the Peoria and Pekin Union Railway Company. Because that request was tied to and pending the NS/UP transaction, the Board rejected the related application once it rejected the main merger filing.

The second was a control request involving the Terminal Railroad Association of St. Louis. The filing described that proposal as a “minor” transaction, but the STB concluded it should be treated as a “significant” transaction instead. It therefore rejected that control application as well.

Next steps and deadlines for Union Pacific and Norfolk Southern

Union Pacific and Norfolk Southern must now tell regulators whether they plan to try again. NS/UP have until Feb. 17, 2026 to file a letter informing the Board and the public on whether they intend to submit a revised application. If they proceed, the revised filing must be submitted by June 22, 2026.

The STB noted that the full decision is available online and includes additional detail and letters submitted by other railroads, including comments that flagged omissions or raised questions about information in the original merger filing.

Industry response: American Chemistry Council

Reaction also came from industry. In a press release, the American Chemistry Council said a deal of this size should not be rushed and praised what it called the STB’s deliberate, data-driven approach. The group said the agency’s modern merger standards require any major rail consolidation to enhance competition rather than reduce it.

The council warned against another “mega-merger” that could leave customers with fewer choices, higher prices, and declining service. It said it will continue working with regulators, policymakers, and stakeholders to ensure any proposed transaction meets the public-interest test and supports the nation’s supply chain, economy, and manufacturing competitiveness.
