According to the Bank’s website, the investment project titled as Istanbul North Rail Crossing Project (INRAIL) will finance the greenfield railway bypass line from Cayirova to Catalca across the Bosphorus Strait via the 3rd Bosphorus Bridge in the North of the Istanbul Metropolitan Area providing a new high-capacity railway link connecting the Asian side of Istanbul to its European side and an alternative to the current Marmaray tunnel. The 122-kilometer (km) long project is proposed as a double track, electrified, signalized, mixed-used line carrying passengers and freight at an operating speed of 160 km per hour (km/h) and 100 km/h, respectively. The planned railway line is proposed to provide direct connections to the major airports, including Sabiha Gokcen and the Istanbul Airport. The project cost is estimated as $8.119 billion and will be co-financed by Asian Development Bank (ADB), Asian Infrastructure Investment Bank (AIIB), European Bank for Reconstruction and Development (EBRD), Islamic Development Bank (IsDB), OPEC Fund for International Development, and the World Bank along with the Government of Turkiye. The inter financial institutions collaboration is being coordinated by the World Bank. This will be the first transport sector project of ADB to be processed in Turkiye. The project is to be processed under the Full Mutual Reliance Framework (FMRF), the World Bank is designated lead lender and ADB is the trail lender.
