World Bank Anchors $6.75 Billion Financing for Istanbul North Rail Crossing

The World Bank formally approved a $2 billion loan, serving as anchor financing for the Istanbul North Railway Crossing Project, designated INRAIL. This commitment, finalized on March 31, 2026, completes a coordinated financial package totaling $6.75 billion secured from six multilateral development banks (MDBs). The substantial capital infusion underscores the project’s strategic goal: to fundamentally enhance rail connectivity across the Bosphorus Strait and solidify Turkey’s position as a pivotal logistics nexus linking the European Union, Central Asia, and the Middle East.

The INRAIL initiative involves constructing a 127-kilometer electrified, high-capacity railway segment, with nearly half of its alignment running through tunnels for improved resilience. This new corridor will integrate the existing, rail-ready Yavuz Sultan Selim Bridge, bypassing congested northern sectors of the Istanbul metropolitan area. The route is planned to connect Gebze, Sabiha Gökçen Airport, the bridge structure, Istanbul Airport, and Halkalı, establishing the first direct rail link between the city’s two major international airports and creating an uninterrupted northern rail corridor.

Official projections from Turkish Minister of Transport and Infrastructure Abdulkadir Uraloğlu indicate the line will generate significant throughput, anticipated to manage 33 million passengers and 30 million tons of freight annually upon full operation. This scale positions the project as the largest foreign-funded railway endeavor in Turkish history, directly targeting a critical chokepoint in Eurasian trade. The most significant expected impact is a fifteenfold increase in rail freight crossing the Bosphorus, projected to surge from approximately 3 million tons per year to an estimated 50 million tons annually, thereby improving reliability and transit times for freight operators.

This development directly addresses the current logistical constraint that forces heavy reliance on trucking across the strait, as the existing Marmaray tunnel is primarily allocated for passenger services with limited freight access. By removing this bottleneck, Turkey reinforces its role in key international trade arteries, including the Trans-Caspian International Transport Route (TITR), or Middle Corridor, and the Iraq Development Road. World Bank Country Director for Turkey Humberto Lopez noted that this action boosts Turkey’s competitiveness as a logistics hub bridging continents.

The Yavuz Sultan Selim Bridge, which the new line will incorporate, opened in August 2016 and features the world’s widest suspension bridge deck at 58.5 meters, accommodating eight highway lanes alongside two rail tracks designed for speeds up to 160 km/h. The successful execution of INRAIL, supported by institutions including the Asian Development Bank (ADB), Asian Infrastructure Investment Bank (AIIB), European Bank for Reconstruction and Development (EBRD), Islamic Development Bank (IsDB), and the OPEC Fund for International Development, is crucial for realizing Turkey's ambition as a leading Eurasian logistics center. Tender preparations are reportedly underway, with the Turkish government expressing hope that physical construction work can commence within 2026, a development anticipated to create up to 414,000 better-paying jobs across national rail corridors.
