Middle Corridor Container Traffic Surges 450% as Azerbaijan Railway Nears Completion

The Trans-Caspian International Transport Route — commonly known as the Middle Corridor — is experiencing extraordinary growth in 2026, with container traffic rising 450 to 500 percent compared to the same period in the prior year. The surge reflects a structural shift in Eurasian freight logistics as shippers permanently redirect cargo away from Russian transit networks and toward the Caspian-Caucasus-Turkey route linking China and Central Asia to European markets.

The Middle Corridor spans Kazakhstan, Azerbaijan, Georgia, and Türkiye, with connections extending westward into the European Union and eastward to Chinese rail networks. The route has been gaining share for three consecutive years, but the acceleration in 2026 has surprised even optimistic forecasters. Port operators along the Caspian coast are expanding berth capacity, and rail operators are procuring additional rolling stock to handle volumes that were never anticipated at this pace of growth.

A critical infrastructure milestone is imminent: Azerbaijan's section of the TRIPP route, specifically the Horadiz-Aghband railway, is nearing completion and is expected to be fully commissioned by the end of 2026. Designed with an initial throughput capacity of 15 million tons, the line will provide the Corridor's South Caucasus segment with substantially expanded capacity at a time when existing infrastructure is operating at or near its limits. The railway also directly serves the Zangezur corridor geometry, connecting to Armenian territory and ultimately to Turkey.

Kazakhstan has announced plans for an intergovernmental agreement with Azerbaijan in 2026 to formalise the Middle Corridor's status as a priority transport route, building on the joint venture — Middle Corridor Multimodal Ltd — established by the national rail operators of Azerbaijan, Kazakhstan, and Georgia in 2023, with China's accession in August 2025. The inclusion of Chinese rail operators in the governance structure dramatically improves interoperability and reduces dwell times at interchange points.

The European Commission has published a meta-study funded by EU institutions mapping investment needs across the Corridor, identifying key stretches where infrastructure is missing, outdated, or insufficient for today's volumes. The study emphasises the South Caucasus link as one of the highest-priority investment areas, with bottlenecks at Black Sea ports and legacy rail segments requiring urgent capital allocation. According to the European Commission, the study maps where investment is most urgently needed to rebuild trade routes between Europe and Central Asia via the Caucasus.

For Azerbaijan, the Corridor's growth reinforces the country's strategic positioning as Central Asia's gateway to Europe. Transit revenues are increasingly supplementing hydrocarbon export income, and Baku has been active in upgrading Alat Free Economic Zone — a key logistics hub on the western Caspian coast — to capture higher-value cargo handling and warehousing business. The Zone's preferential tax and customs regime is drawing interest from global logistics companies seeking a South Caucasus operational base.

Georgia similarly benefits as the Corridor's western anchor in the South Caucasus. Poti and Batumi ports handle the transshipment of most Corridor cargo crossing the Black Sea, and Georgian Railways is investing in capacity expansions co-financed by EBRD and EU instruments. As noted by The Astana Times, Azerbaijan's growing role as the Corridor's core transit hub is reshaping regional logistics geopolitics in ways that will compound over the coming decade.
