Söğütlüçeşme railway station (Turkish: Söğütlüçeşme İstasyonu) is a railway station in the Kadıköy district of İstanbul, Turkey. The station is 1.46 km (0.91 mi) away from Haydarpaşa Terminal and during peak hours, is one of the busiest railway stations in Turkey. Söğütlüçeşme is currently the only station that has a connection with rapid transit, as the eastern terminus of the İstanbul BRT is located adjacent to the station. The station is serviced by the Haydarpaşa-Gebze Line, Haydarpaşa-Adapazarı Regional as well as all intercity service on the route. Since the station is integrated with the citywide Akbil smartcard, service from Söğütlüçeşme to Haydarpaşa and points east up to Gebze are 1,75TL, by commuter train.
The original station was built in 1872 by the Ottoman Government as part of their line to İzmit. In 1888 the station was taken over by the Anatolian Railway (CFOA) as the Ottoman Government sold it to a private company. In 1890, service started to Ankara from Haydarpaşa running through Söğütlüçeşme. In 1927, the Turkish State Railways absorbed the CFOA and the station was under new management. In the following years, commuter service was increased, especially after World War II with the arrival of new locomotives and rolling stock. In 1969, the line was electrified and built on top of the viaduct that it stands on today, for new improved commuter rail service. In 2007, connection to the rest of the city's rapid transit was opened with the construction of the Istanbul Metrobus.
