Definition
The Gebze Metro (Turkish: Gebze Metrosu) is a planned rapid‑transit railway line intended to serve the city of Gebze in Kocaeli Province, Turkey. It will constitute the first metro system in the province and is designed to provide high‑frequency, grade‑separated urban rail service within the Gebze metropolitan area.
Overview
The project was approved by the Turkish Ministry of Transport and Infrastructure in the mid‑2010s, with construction reportedly commencing in the early 2020s. As of the most recent publicly released updates (2023‑2024), the line is under construction, with an anticipated opening date in the latter half of the 2020s. The Gebze Metro is intended to complement existing commuter‑rail services, such as the Marmaray line that currently terminates at Gebze, by offering faster intra‑city connections and alleviating road traffic congestion.
Etymology / Origin
The name combines “Gebze,” the Turkish designation for the city where the system is to be built, with “Metro,” a shortened form of “metropolitan railway,” a term widely used internationally to denote urban rapid‑transit systems. The Turkish word metro is itself borrowed from the French métro, an abbreviation of chemin de fer métropolitain (“metropolitan railway”).
