Türkiye, Azerbaijan and Georgia Open Upgraded Baku Tbilisi Kars Railway for Middle Corridor Trade
By Bosphorus News Geopolitics Desk
Türkiye, Azerbaijan and Georgia launched full capacity operations on the upgraded Baku Tbilisi Kars railway, known as BTK, at a ceremony held on June 2, 2026, at the Akhalkalaki Railway and Logistics Complex in southern Georgia.
The opening marked a new stage for the Middle Corridor, the trans-Caspian route linking China and Central Asia with Europe through Azerbaijan, Georgia and Türkiye.
Georgian Prime Minister Irakli Kobakhidze, Georgian Economy and Sustainable Development Minister Mariam Kvrivishvili, Azerbaijani Digital Development and Transport Minister Rashad Nabiyev and Turkish Transport and Infrastructure Minister Abdulkadir Uraloğlu attended the ceremony.
Representatives from Kazakhstan and Uzbekistan, diplomatic missions, railway operators and port authorities also took part, giving the opening a wider Central Asian and Caspian dimension.
The modernisation focused on the Georgian section of the route, especially the Marabda Kartsakhi line. The project covered 180 kilometres, including the rehabilitation and reconstruction of 153 kilometres of existing railway and the construction of a new 27 kilometre section built to European standards.
Azerbaijani officials said the work included 13 stations, 55 bridges, eight traction substations and more than 320 railway structures. The upgraded line is expected to raise annual freight capacity from around 1 million tons to 5 million tons.
The full BTK route links Baku with Kars through Georgia and gives the South Caucasus a direct railway connection to Türkiye's rail network and onward routes toward Europe.
Nabiyev said Azerbaijan had invested in the section crossing Georgian territory and described the modernisation as a strategic step for the Middle Corridor.
"This is not only a repair project, but a strategic decision to transform the line into the backbone of the Middle Corridor," Nabiyev said at the ceremony.
Uraloğlu said the transport vision jointly advanced by Türkiye, Georgia and Azerbaijan was critical for the future of connectivity between Asia and Europe. His remarks placed the railway inside a broader supply chain debate, where capacity figures carry weight only if they translate into regular cargo flows, predictable transit times and confidence among logistics users.
The railway opening also strengthens an existing trilateral framework linking transport, energy and regional security across the South Caucasus. Türkiye, Azerbaijan and Georgia have increasingly treated corridor policy as a shared strategic file rather than a series of separate infrastructure projects.
That wider framework has gained importance as governments and companies reassess east west routes. The Middle Corridor has drawn greater attention because it offers a land based option through countries outside the main sanctions environment affecting Russia-linked transit.
Azerbaijani transport expert Rauf Aghamirzayev told Trend that the BTK line's main strategic value lies in its passage through countries not subject to sanctions. That assessment explains why the project is now being watched beyond the railway sector.
The opening also comes as the South Caucasus faces a broader corridor race tied to trade, critical minerals and geopolitical access. BTK, the Middle Corridor and Armenia-linked transit proposals are increasingly part of the same regional debate over who controls the routes between Asia, the Caspian basin, Türkiye and Europe.
Türkiye is also building the Kars Dilucu railway, a 224 kilometre line designed to connect eastern Türkiye with the Nakhchivan border. Azerbaijani officials have signalled parallel work on a route through Nakhchivan, while the Horadiz Aghband section is expected to advance Azerbaijan's own connection toward the Armenian border.
That future link is often discussed under the Zangezur Corridor framework, but its implementation remains politically dependent. Any route through Armenia requires Yerevan's approval, while the Türkiye Armenia land border remains closed. The planned corridor therefore remains a prospective layer in the regional network, not an already functioning extension of BTK.
The opening adds weight to Türkiye's wider Middle Corridor agenda, which now spans rail freight, Caspian energy routes, Central Asian connectivity and digital logistics planning.
The timing also gives the railway broader relevance. Maritime chokepoints from the Gulf to the Red Sea have pushed governments and companies to pay closer attention to overland redundancy. BTK does not replace sea routes, but it strengthens one of the few rail based options that can move cargo between Asia and Europe through the Caspian and South Caucasus space.
Passenger services remain a separate file. The Baku Tbilisi passenger train resumed on May 26 after a six year pause, but a full Baku Kars passenger service across the BTK route has not yet been announced.
The operational test now moves from ceremony to cargo volumes. The upgraded line gives Türkiye, Azerbaijan and Georgia a stronger infrastructure base, but the Middle Corridor's credibility will depend on frequency, cost, border procedures, port coordination and stable transit times across several jurisdictions.
BTK's capacity has increased fivefold. Its strategic value will be measured by whether the route can become a dependable habit for shippers moving goods between China, Central Asia, the South Caucasus, Türkiye and Europe.
