Union Pacific has announced an $85 billion agreement to acquire Norfolk Southern in a stock-and-cash deal that would create the first U.S. coast-to-coast freight rail operator. The merger would combine Union Pacific’s western U.S. network with Norfolk Southern’s 19,500-mile network in 22 eastern states.
If approved, the merger would reshape domestic freight logistics, consolidating Class I operators from six to five and potentially triggering further consolidation among competitors BNSF and CSX. The combined company would hold an estimated 43% market share across multiple freight categories.
The proposed deal is subject to regulatory approval by the Surface Transportation Board (STB), with a formal application expected within six months and final decision anticipated by early 2027. The companies estimate $2.75 billion in annualized synergies from the transaction.
The deal has drawn opposition from major rail unions, including SMART-TD and the Brotherhood of Railroad Signalmen, citing concerns over service reliability, job security, and safety. Shippers have also voiced caution, warning of potential service disruptions and rate increases.
Union Pacific will fund roughly 70% of the transaction through stock, with the remaining value in cash. If terminated under certain conditions, the company will pay a $2.5 billion termination fee to Norfolk Southern.
This would be the largest railroad merger since Canadian Pacific’s $31 billion acquisition of Kansas City Southern in 2023.
