The intensity of political, legal, and competitive pressures surrounding the STB review signals that outcomes could reshape how goods move across North America for years to come.

Companies should monitor the STB proceedings closely and prepare contingency plans that account for both approval and rejection scenarios, each of which carries distinct implications for network design and carrier relationships.
