Major Railroad Mergers and Consolidations

The STB has exclusive jurisdiction over railroad mergers. Under revised merger rules adopted in 2001, the STB will not approve a merger application involving Class 1 railroads (major merger) unless the transaction is shown to be in the public interest. STB merger review involves rigorous scrutiny of the proposal and allows for public participation.

As part of any merger review, the merger rules require the railroads to submit a service assurance plan. The merger rules also provide for the STB to impose conditions upon a merger, as appropriate, and oversee the combined carriers' operations for a period of at least 5 years following the merger.
