What is the 2.2 million truck diversion claim, and why is it controversial?

The NS-UP merger application claims a diversion of 2.2 million annual truck moves to rail. Tonsager criticizes this figure as vague and unsubstantiated, noting the railroads have not published lane-level details specifying which shippers, corridors, and volumes support it. For context, 2.2 million truckloads roughly equals the annual volume of Knight-Swift, making the claim relatively modest but still unproven without specifics.

Why does the CN settlement matter to the NS-UP merger?

The CN settlement repositions Canadian National as strategically relevant after being sidelined in earlier merger discussions. More importantly, it grants Union Pacific access to CN's Elgin, Joliet & Eastern Railway, a Chicago bypass route that would reduce intermodal dwell times and improve network fluidity for cross-country shipments. This asset is considered underreported but operationally significant.

Who actually controls intermodal freight relationships—railroads or their customers?

Railroads function as wholesalers, not the relationship owners. Direct control rests with intermodal marketing companies (Schneider, J.B. Hunt, Maersk) and ocean carriers, not the beneficial cargo owners (e.g., Walmart, Home Depot). This means railroads have limited direct leverage to drive volume growth and must rely on IMCs and steamship lines to translate network improvements into actual shipments.

What past failures suggest current collaboration agreements may not replace consolidation?

Tonsager cites historical interline arrangements between IC, WC, and CN that collapsed due to pricing disputes and customer ownership conflicts. A merged UP-NS network could offer end-to-end solutions (e.g., Norfolk to Kansas City) directly to ocean carriers like Maersk, addressing this structural weakness in the current fragmented rail system.

What is the Surface Transportation Board's role, and when might a decision arrive?

The STB has final regulatory authority over the merger and will make the decision (unlike other countries where Treasury or Justice Departments intervene). The process has already extended roughly one year. Tonsager expressed confidence in the STB's process but urged the parties to accelerate, noting the latest CN filing is expected to shift the board's calculus.

The signal

The proposed Norfolk Southern-Union Pacific merger has regained momentum following a settlement with Canadian National, but industry veterans remain skeptical about the deal's core freight-diversion promise. 2 million truck-move diversion claim sounds ambitious, the railroads have failed to publish detailed lane-level specifics showing which shippers, corridors, and volumes support this figure. A critical insight from Tonsager's analysis centers on the structural realities of intermodal freight: railroads function primarily as wholesalers, not direct service providers.

B. Hunt, Maersk) and ocean carriers—not the railroads themselves. This fundamental dynamic limits how much operational improvement a merged entity can translate into actual freight diversions without customer buy-in.

The merger process has already extended roughly one year, with the STB (Surface Transportation Board) poised to make the final decision. While the CN settlement does unlock strategic assets—particularly CN's Elgin, Joliet & Eastern bypass around Chicago—supply chain professionals should remain cautious about merger projections until railroads demonstrate specific, verifiable freight-capture plans with named shippers and defined lanes.

Frequently Asked Questions

What This Means for Your Supply Chain

Simulation Suggestion

strategic

What if the NS-UP merger delivers only 50% of its promised truck diversions?

Model a scenario where actual truck-to-rail diversion achieves 1.1 million moves annually (instead of 2.2 million) over the next 2-3 years. Adjust intermodal capacity, pricing, and lane-level routing through key corridors (Chicago-Kansas City, Oklahoma City-Atlanta, Norfolk-Minneapolis) to reflect conservative customer adoption rates.

Simulation Suggestion

this month

What if Chicago bypass (EJ&E) reduces intermodal dwell by 2 days across key east-west corridors?

Simulate the operational and cost impact of the Elgin, Joliet & Eastern bypass enabling a 2-day reduction in dwell time for containers moving through Chicago on Norfolk-to-Kansas City and Norfolk-to-Minneapolis lanes. Model effects on in-transit inventory, demurrage costs, and competitive positioning vs. trucking for shippers in the Upper Midwest.

Simulation Suggestion

strategic

What if STB approval delays extend beyond 18 months, forcing shippers to lock in alternative capacity?

Model a prolonged regulatory review (18+ months) where shippers and IMCs commit to alternative carriers (BNSF, CSX) or trucking capacity rather than wait for merged UP-NS efficiency gains. Assess capacity constraints, rate escalation, and customer defection risk if merger momentum stalls.
