Rail Baltica and Via Carpatia Could Strengthen NATO’s Eastern Logistics Network

Eastern European countries are investing in transport infrastructure that could improve regional connectivity and make it easier to move military equipment across NATO’s eastern flank. Two major projects highlighted in this analysis are Rail Baltica, which is designed to connect the Baltic states with the European rail network, and Via Carpatia, a north–south road corridor intended to link countries from the Baltic region toward southeastern Europe.

Rail Baltica is being developed using the European standard rail gauge of 1,435 millimeters, replacing the need to rely exclusively on the broad-gauge network inherited from the Soviet era. Once operational, the railway could improve passenger and freight connections while offering additional options for transporting military supplies and heavy equipment. Its military value will depend on completion, capacity, border procedures, and the availability of suitable loading and unloading facilities.

Via Carpatia complements these rail investments by improving road links between Poland and countries farther south. Together with other regional transport routes, it could provide NATO members with more options for moving personnel, vehicles, and supplies during exercises or emergencies. Rail transport can move large quantities of equipment efficiently, while road networks provide flexibility for reaching locations beyond railway terminals.

The report argues that these infrastructure projects could reduce logistical dependence on routes passing through Russia. However, they do not automatically isolate Kaliningrad, Russia’s Baltic Sea exclave. The region retains maritime connections, while transit arrangements through Lithuania remain governed by applicable European Union rules and security restrictions.

The proposed Baltic–Black Sea–Aegean corridor represents a broader effort to connect transport networks across eastern and southeastern Europe. Its strategic significance lies in improving resilience, increasing the number of available routes, and supporting coordination among allied countries—not in creating an automatic blockade of Russian territory.

Ultimately, the projects could strengthen NATO’s logistical flexibility, but their impact will depend on construction progress, funding, interoperability, and how effectively civilian infrastructure can support military transportation when required.
