Union Pacific–Norfolk Southern Merger Risk: Build a Rail Rate Exposure Map Before Approval
The proposed Union Pacific–Norfolk Southern combination is not simply a railroad transaction. For shippers, it is a reason to identify where network concentration could turn into higher transportation costs or weaker service—and to do that work before any regulatory decision changes negotiating conditions.
The proposed transaction is valued at $85 billion. If completed, the combined railroad would operate a 52,215-mile transcontinental network, according to Supply Chain Dive. That coast-to-coast reach could reduce interchange friction on some lanes, but scale alone does not guarantee better shipper outcomes. The same analysis cited an academic estimate that the combined carrier would hold more than 40% market share across most commodity groups.
The merger still faces regulatory scrutiny. Reuters reported that the Surface Transportation Board paused its review in May 2026 while seeking more information. More recently, shipper anxiety intensified after Union Pacific CEO Jim Vena said rates could be raised on customers opposing the deal, according to Supply Chain Dive.
Whatever the final outcome, waiting is the wrong procurement strategy. Shippers should build a rail rate exposure map now.
Start with facilities, not the national network
A merger map showing thousands of route miles can obscure the practical question: what alternatives exist at each origin and destination?
For every plant, distribution center, transload point and customer siding, document:
- Serving railroad and reciprocal-switching options
- Nearest competitive railhead or intermodal terminal
- Commodity, annual volume and seasonal peak
- Current contract expiration, rate basis and fuel surcharge
- Required equipment type and loading constraints
- Truck capacity and highway access within a realistic radius
- Cost and transit time to the next-best gateway
Classify each location by substitutability. A facility served by two railroads with nearby intermodal capacity has a different risk profile from a captive bulk shipper whose next option requires a 100-mile truck dray. The latter needs earlier negotiations and a larger contingency budget.
Quantify lane-level rate exposure
The baseline must be more detailed than total annual rail spend. Preserve every current quote, contract rate, surcharge rule, minimum volume commitment and service promise at the lane level. Then calculate the effect of plausible changes.
For example, model rate increases of 5%, 10% and 15%, but also test operational changes: an extra interchange day, fewer weekly departures, higher demurrage, or a tighter free-time allowance. A nominally unchanged linehaul rate can still produce a meaningful landed-cost increase if slower or less predictable service forces more safety stock.
Prioritize lanes using four factors:
- Spend at risk: annual volume multiplied by the modeled rate increase.
- Competitive scarcity: the number and quality of viable carrier or mode alternatives.
- Operational sensitivity: the cost of delay, shutdown or missed customer appointments.
- Conversion lead time: how long it takes to qualify another route, terminal or carrier.
A low-volume movement carrying a shutdown-critical input may deserve more attention than a high-volume lane with three ready substitutes.
Pre-approve alternatives before they are urgent
An alternative is not real merely because it appears in a routing guide. Procurement and operations should jointly validate capacity, equipment, lead time and total cost for three types of fallback.
Truck conversion: Identify the maximum economical distance, required trailer or bulk equipment, driver availability and surge-rate ceiling. Include the cost of additional loading labor and appointment changes.
Intermodal conversion: Confirm ramp capacity, dray distance, container availability, cutoff times and whether transit variability fits the inventory policy.
Alternate rail routing: Price the move through a competing Class I, short line, transload site or different gateway. Account for switching charges, handoffs and terminal dwell—not just the quoted linehaul rate.
For each fallback, set an activation threshold. A shipper might shift 20% of volume when the rail rate rises 8%, tender acceptance falls below 95%, or average transit exceeds the baseline by one day for four consecutive weeks. Pre-approved thresholds prevent teams from debating the strategy after performance has already deteriorated.
Separate merger effects from normal volatility
Rail prices and service fluctuate for many reasons, including fuel, weather, labor, commodity demand and network construction. A credible exposure program therefore needs a frozen pre-merger baseline and appropriate comparisons.
Track each exposed lane against its own historical performance and against similar, less-affected lanes. Monitor linehaul rate per car, fuel surcharge, accessorials, transit time, dwell, on-time delivery and claims. Record rejected tenders and forced mode changes as well. If a rate rises while fuel and comparable lanes remain stable, the exception deserves review.
This evidence is valuable even if the merger is rejected. It improves contract negotiations, exposes captive facilities and reveals where the network lacks resilience.
Turn the map into a control system
CXTMS can connect contracts, quotes, shipments and service events so the exposure map remains operational rather than becoming a one-time spreadsheet. Teams can preserve baseline pricing, compare new quotes with historical lane costs, and flag changes in transit time, tender acceptance or accessorial spend.
The goal is not to predict the regulator’s decision. It is to know exactly where the business is vulnerable and which response is already approved. Shippers that complete that work now will enter any post-decision market with better data, faster options and stronger negotiating leverage.
