Sapanca station is a railway station along the Istanbul-Ankara railway in the town of Sapanca, Turkey. It is serviced by the Istanbul-Arifiye limited-stop regional train, the Ada Express. Until 2012, Sapanca was a stop on the Haydarpaşa-Adapazarı Regional, which operated frequently. Other express trains heading for Ankara and points beyond would skip the station. Today, the high-speed Yüksek Hızlı Tren service passes the station on its own right of way. Sapanca is 123 km (76 mi) away from Haydarpaşa Terminal in Istanbul.
