Türkiye and the European Union are accelerating efforts to expand rail freight transport along the so-called Middle Corridor between Europe, Central Asia and China, tying new regulations, investment platforms and pilot projects to a route that has gained strategic weight as governments seek alternatives to traditional Eurasian trade lines.

Middle Corridor gains momentum in shifting Eurasian trade

The Middle Corridor, formally known as the Trans-Caspian International Transport Route, links China to Europe via Kazakhstan, the Caspian Sea, Azerbaijan, Georgia and Türkiye. It combines rail and ferry segments to offer delivery times that are typically faster than sea and less costly than air, while bypassing routes that cross Russia or congested maritime chokepoints.

Cargo volumes moving along the corridor have risen sharply in recent years, supported by the 2017 launch of the Baku–Tbilisi–Kars railway and expanded capacity on Caspian crossings. Publicly available figures from regional operators and international financial institutions indicate that freight flows more than doubled between 2022 and 2024 and are forecast to continue climbing through the decade as new terminals, sidings and digital systems come online.

Türkiye has positioned itself as a central hub on this emerging axis, investing in ports, logistics centers and rail lines that connect its eastern border with major European gateways. Analysis by multilateral lenders and policy institutes has highlighted the potential for the route to carry over 10 million tons of cargo annually by 2030, provided infrastructure bottlenecks and border procedures are addressed.

For the European Union, the corridor now features in broader efforts to diversify supply chains and reduce dependence on a limited number of transit options between Europe and Asia. The route is being framed as complementary to existing northern and southern land and sea pathways, with rail freight regarded as a key tool to cut transport-related emissions and strengthen resilience.

New EU platform and regulations target smoother cross-border rail

In late June 2026, the European Union launched a Connectivity Agenda Platform focused on developing the Middle Corridor and related links under its Global Gateway investment strategy. According to published coverage of the launch, the platform is designed to coordinate transport, energy and digital infrastructure projects with countries across Central Asia, the South Caucasus and Türkiye, and to improve the operational performance of the Trans-Caspian route.

The platform builds on earlier technical work and financing aimed at ports, rail lines and customs modernization along the corridor. It is expected to serve as a venue where EU institutions, member states, partner governments and international lenders can align project pipelines, standardize procedures and prioritize investments that deliver the largest capacity and time savings for freight.

Brussels has, in parallel, adopted new rules intended to improve cross-border rail traffic inside the EU. A regulation on the use of railway infrastructure capacity entered into force in May 2026, with the aim of reducing bottlenecks at national borders and improving the predictability of freight paths across the single market. The framework encourages more coordinated timetabling and capacity allocation, which in turn is expected to make long-distance freight services from Türkiye and the broader Middle Corridor more competitive once they enter EU territory.

Together, the connectivity platform and the rail capacity regulation signal a more structured EU approach to rail freight corridors, including those that originate beyond the bloc’s borders. Analysts suggest that this could lower transaction costs for logistics firms using Türkiye as a gateway, particularly when combined with upgraded terminals in Central and Eastern Europe that can receive block trains arriving from the Caucasus and Anatolia.

Türkiye prioritises rail in transport vision and EU connectivity

Official planning documents and recent project announcements indicate that Türkiye is elevating railways in its long-term transport vision. While road still carries the vast majority of domestic freight, Ankara has committed to raising rail’s share by building and modernising lines that serve both national logistics needs and international transit.

Key elements include upgrades along the Halkalı–Kapıkule route to the Bulgarian border, co-financed with EU funds, and improvements on the east–west axis linking Kars, Erzurum and central Anatolia to ports and industrial zones. Studies referenced by the World Bank point to particularly acute capacity constraints on some eastern segments used by Middle Corridor trains, where passenger and freight services currently share single-track sections.

The Eastern Türkiye Middle Corridor Railway Development Project, prepared with World Bank support, aims to address those constraints by modernising infrastructure, improving signalling and expanding sidings and passing loops. Project documentation underscores the potential climate benefits, noting that shifting freight from road to electrified rail can significantly cut emissions per ton-kilometre while also reducing congestion and accident risks on highways.

Publicly accessible research by European and regional think tanks also stresses that better rail connectivity within Türkiye is essential if the country is to fulfil its ambition of acting not only as a transit territory, but also as a logistics and manufacturing hub connected to both EU and Asian value chains. Increased interoperability with EU rail standards is seen as a central part of that strategy.

Intermodal pilots and private operators test new freight patterns

Beyond high-level platforms and long-term infrastructure projects, concrete steps are already being taken to move more cargo by rail along the Middle Corridor. At the end of June 2026, Türkiye and the EU highlighted the results of an intermodal transport initiative that tested combined rail and road services on several routes linking industrial centres in Central Anatolia and Western Europe.

According to public reporting on the project, these pilot services demonstrated that competitive transit times are achievable when border procedures are streamlined and train paths are coordinated across multiple national networks. The initiative, which involved infrastructure managers, logistics companies and public agencies, aims to make rail freight a more attractive option for shippers that currently rely on road or sea.

Private operators are also expanding their presence on Türkiye-related corridors. Recent industry news shows European and regional logistics firms announcing new block train services that connect Central European hubs with Türkiye, sometimes via Ukraine and the Black Sea and sometimes directly through the Balkans. Several of these operators have indicated that they view onward connections via the Middle Corridor to Central Asia and western China as a key growth area.

Domestic companies in Türkiye, meanwhile, have signed partnership and capacity agreements with railways and logistics providers in China, Kazakhstan, Azerbaijan and Georgia to increase the share of containers routed through the Middle Corridor. These deals typically focus on guaranteed train slots, harmonised tariffs and joint marketing to global shippers looking to diversify supply chains.

Bottlenecks, borders and the push for faster procedures

Despite growing momentum, Türkiye and the EU still face a series of practical obstacles to significantly increasing rail freight volumes along the Middle Corridor. The route traverses multiple jurisdictions, each with its own customs regimes, technical standards and visa rules for transport workers, which can translate into delays and inconsistencies.

Reports from regional media and trade publications highlight that differences in rail gauge between Central Asia, the South Caucasus and Türkiye require time-consuming transshipment or bogie changes. Capacity on some Caspian Sea ferry links remains limited, while terminals at key border crossings, including on Türkiye’s eastern frontier, can become congested when surges in cargo coincide with infrastructure work or weather disruptions.

Turkish officials have repeatedly called in public forums for faster border procedures, predictable visa issuance for drivers and train crews, and wider use of digital systems to share data among customs authorities. Such measures, they argue, are critical if the benefits of newly built or rehabilitated rail lines and ports are not to be lost to waiting times at borders.

EU institutions and partner governments along the corridor have acknowledged these issues in recent strategy papers and meeting communiqués, and have pledged to work on harmonising documentation, expanding capacity at critical nodes and piloting electronic transit systems. For shippers and logistics providers, the pace at which these operational bottlenecks are resolved will be a decisive factor in determining how quickly rail freight on the Middle Corridor can scale up from a niche alternative to a mainstream Eurasian trade artery.
