A group of state attorneys general has renewed its call for the Surface Transportation Board (STB) to reject the proposed merger between Union Pacific (UNP) and Norfolk Southern, which would create a transcontinental rail network.

Details of the Action

The attorneys general filed a formal comment with the STB urging denial of the application, arguing that the merger would reduce competition in the rail freight sector, potentially raising costs for shippers and consumers. The number of participating attorneys general was not specified.

Company Stance

Neither Union Pacific nor Norfolk Southern has issued an official response to the comment. The companies previously submitted the merger application, stating it would improve efficiency and lower transportation costs.

Precedents and Context

This is not the first time state attorneys general have opposed a major rail merger. Similar objections were raised in past consolidation attempts, citing antitrust concerns. The STB has recently tightened its review standards for large mergers.

Potential Financial Impact

If the STB rejects the application, the companies may need to revise terms or abandon the deal, affecting their strategic plans. While rejection could preserve competition, it might also deny the companies expected economies of scale.

Frequently Asked Questions

It is a proposal filed with the Surface Transportation Board to merge the two companies into a transcontinental rail network.
