The Gebze Metro (Turkish: Gebze Metrosu) is an under-construction rapid transit system in Gebze and Darıca, Turkey. The system consists of a single 15.4 km (9.6 mi) long line running north from Darıca to Gebze. The line will interchange with TCDD Taşımacılıkhigh-speed and intercity trains along with Marmaray commuter trains to Istanbul at Gebze railway station. The metro system will be the first network to exist outside of a provincial capital in Turkey, as Gebze and Darıca are located within the Kocaeli Province.
Most of the metro line will be underground, except for a 900 m (3,000 ft) section which will be at-grade. Journey time is expected to be 19 minutes and the projected daily ridership is expected to 4,800. A maintenance facility and a control center will be constructed at Pelitli, in north Gebze. Construction began in late 2018, and is expected to open in late 2025.
