Russian Railways Rerouting Leaves Shipments Rejected, Container Rates Up 57.4%

Russia’s port workaround has run into a second bottleneck. Cargo diverted from constrained southern ports is arriving at rail corridors that lack enough spare capacity, leaving shipment applications rejected or cancelled, freight trains idle and wagons in short supply. Soyuzsahar, the Russian Sugar Producers Union, cited a 57.4% increase in container rates, from approximately $3,260 to $5,130 per container.

The pressure follows disruption to maritime export capacity at southern ports since August 2026. Those Black Sea and Sea of Azov facilities had handled about 90% of Russia’s seaborne grain exports, making diversion a large systems-integration problem rather than a matter of selecting another port. The replacement route also needs available trains, equipment, terminal capacity and paths through the rail timetable.

The alternative corridors were already heavily used

In August, export shipments through Russia’s main northwestern border crossings reached 13 million tonnes, up 18.8% from a year earlier, according to the Institute for Natural Monopoly Research. Grain traffic rose sixfold, while ferrous-metals exports increased 91.6% and coal shipments climbed 56.7%. Shipment requests now exceed the capacity of rail lines serving northwestern ports.

Alina Koryagina, a business development partner at consultancy Neo, said the Russian rail network was operating at capacity before the diversion. She described trains moving more slowly, waiting longer for available paths and using track less efficiently. Those effects reinforce one another: slower circulation keeps locomotives, wagons and containers occupied for longer, reducing the equipment available for subsequent loads.

Russian Railways said it deployed the necessary resources to direct traffic toward northwestern and eastern regions and remains in contact with shippers. Reallocating crews and equipment can improve the use of available capacity, but it does not immediately add train paths or increase port-terminal throughput.

Freight prioritization is also redistributing the shortage. Grain was subsequently moved into the railway’s third-highest priority category, allowing it to move ahead of some other export cargo. Reporting on coal flows indicates that Russian Railways then reduced coal-shipment plans to northwestern terminals as agricultural traffic increased. Priority can protect one supply chain under congestion, but when total demand remains above capacity, it does so partly by delaying or displacing another.

Diversion moves congestion rather than eliminating it

This is a familiar limitation in multimodal freight systems. A 2026 transportation modeling study, using the Port of Los Angeles as its case rather than Russia, examined rerouting, terminal queues and substitution between transport modes. It found diminishing benefits as the substitute modes approached their capacity limits. Once the buffer is consumed, additional diversion creates more waiting and congestion spillback instead of restoring the lost throughput.

A comparable U.S. experience also shows why rerouting is a contingency measure rather than free replacement capacity. During 2022 labor uncertainty, shippers shifted cargo between ports and away from some rail movements, but the diversions brought longer lead times, additional logistics complexity and congestion at receiving ports, according to industry reporting on those supply-chain changes. The initiating events differ, but the operating constraint is the same: an alternative corridor helps only while it retains spare capacity.

That boundary also appears in Eurasia’s broader freight network. The Middle Corridor linking China and Europe has grown rapidly, yet physical capacity, repeated handovers, port constraints and border processes keep it far smaller than the principal northern rail route. Fast growth from a small base does not make an alternate corridor capable of absorbing the full load of a much larger incumbent route.

For Russian shippers, the rising prices reflect the scarcity now appearing in train paths and equipment. Kommersant reported that wagon and container costs increased by at least 26%, while oil, metals and chemicals businesses also encountered difficulty moving freight by rail. The sixfold rise in grain traffic through the northwestern crossings therefore competes with several established commodity flows rather than occupying an empty corridor.

Road freight offers flexibility for selected shipments but not an inexpensive release valve for bulk exports. Koryagina estimated that trucking costs 2.5 to three times as much as rail per tonne-kilometre. With the rail network reportedly full before the diversion and road transport carrying that cost penalty, redirecting exports has preserved an outlet for some cargo while leaving the underlying capacity shortage unresolved.
