BTK Railway Reaches Full Operational Launch After Azerbaijan-Georgia Deal

The railway authorities of Azerbaijan and Georgia have signed two agreements that pave the way for the full operational launch of the Baku-Tbilisi-Kars (BTK) railway joint enterprise, marking a major milestone in South Caucasus infrastructure development. The BTK line, which provides a direct rail connection from the Caspian Sea through the South Caucasus to Turkey and onward to European rail networks, is a cornerstone of the Middle Corridor trade route.
The agreements, signed in January 2026, address operational coordination, revenue sharing, and technical standards that will enable the joint enterprise to function as a seamless cross-border logistics operation. Previously, the BTK line had operated under interim arrangements that limited its throughput capacity and commercial attractiveness.
"The full launch of the BTK joint enterprise removes one of the key operational barriers to scaling the Middle Corridor," said a regional transport analyst. "With proper coordination between Azerbaijani and Georgian railways, we can expect significant increases in both freight volume and service reliability."
The Astana Times reported that Azerbaijan's growing role as a key trade gateway is closely linked to the performance of the BTK line. Container traffic along the broader Middle Corridor has surged approximately 260 percent in recent years, and the BTK railway is essential for connecting Caspian Sea freight to the Turkish rail network and Mediterranean ports.
The operational improvements come at a critical time. Demand for transit capacity along the Middle Corridor is growing rapidly, driven by European importers seeking alternatives to Russian-transit routes and Central Asian exporters looking for faster access to global markets. The BTK line offers a transit time advantage of approximately 15 days from China to Europe, compared to 45-55 days via traditional sea routes.
Azerbaijan has been investing heavily in complementary rail infrastructure. The Horadiz-Aghband railway, which will connect the Nakhchivan exclave to the main Azerbaijani rail network, is nearing completion with full commissioning anticipated by the end of 2026. The line is designed with an initial throughput capacity of 15 million tons per year, creating additional north-south connectivity that could feed into the BTK east-west corridor.
Georgia has also been upgrading its rail infrastructure to handle increased Middle Corridor traffic. Investments in locomotive procurement, track modernization, and terminal capacity are underway, supported in part by European Union funding under the Global Gateway framework.
The Aze.Media analysis noted that the South Caucasus is riding a logistics wave, with Azerbaijan and Georgia positioned as the primary beneficiaries of the shift in Eurasian trade patterns. The full operationalization of the BTK joint enterprise is expected to accelerate this trend and attract additional investment in warehousing, logistics, and value-added services along the corridor.
