Regulators keep $85bn Union Pacific-Norfolk Southern merger alive, but the clock barely moves

The most consequential railroad deal in a generation cleared a procedural hurdle this week, even as federal regulators signalled that any verdict on the first US coast-to-coast freight network remains a long way off.

The Surface Transportation Board confirmed it has accepted for review the revised application from Union Pacific and Norfolk Southern to combine into a single transcontinental carrier. The Board's unanimous decision simultaneously held the proceedings in abeyance, including the environmental review, and ordered the applicants to file supplemental information by 27 July. The acceptance followed January's rejection of the original filing, which the Board found incomplete for lacking required market-share analyses and a full copy of the merger agreement.

The stakes are enormous. The $85 billion acquisition would create a freight network spanning the East and West coasts, which supporters argue would modernise freight transport and cut shipping costs. If approved, the combined railroad would serve more than 43 states and 100 ports as the first single-line, coast-to-coast freight network in US history. Union Pacific has leaned on fresh data to make its case, claiming the revised filing is the first in rail merger history to use complete actual traffic data from all six North American Class I railroads.

The opposition is formidable. BNSF welcomed the Board's insistence on a complete and compliant application, while the National Industrial Transportation League and the Stop The Rail Merger Coalition also weighed in. The politics cut the other way: President Trump has endorsed the deal, and SMART-TD, the largest rail union, backs it on jobs grounds.

With full Board reviews typically running multiple years, any final decision remains well into the future.
