Istanbul is Turkey's largest rail hub and the only major Turkish city with passenger rail stations on both the European and Asian sides. TCDD Tasimacilik operates the main national services, while YHT high-speed trains use the Marmaray corridor to connect Istanbul with central Anatolia. The city's intercity rail role is split mainly between Sogutlucesme, Halkali, Bakirkoy, Bostanci, and Pendik.
High-speed trains from Istanbul run through Sogutlucesme and selected west-side stations before continuing across the national YHT network. Halkali is the main European-side terminal for international and regional services, including trains toward Thrace and the Balkans. Bakirkoy handles selected long-distance and regional trains on the European side, while Bostanci and Pendik serve Asian-side intercity passengers.
Rail routes from Istanbul run east and southeast toward Ankara, Eskisehir, Konya, and Karaman, west toward Edirne and Kapikule, and cross-border toward Sofia. Inter-station travel between the European and Asian sides uses the Marmaray rail corridor, which links Halkali, Bakirkoy, Sogutlucesme, Bostanci, and Pendik.
