The Ankara Metro (Turkish: Ankara Metrosu) is the rapid transit system serving Ankara, the capital of Turkey. At present, Ankara's rapid transit system consists of two metro lines – the Batıkent Metrosu (M1)and the new Keçiören Metrosu (M4) line opened in 2017, along with the light rail Ankaray line. The Ankaray, the M1 and M4 lines, together transported 104.1 million passengers in 2014. That corresponds to a ridership of approximately 289,155 per day.
In February 2019 all the lines that used to run M1, M2 and M3 were merged to create one line, M1.The Kızılay to Atatürk Cultural Center link of M4 is not yet opened and remains under construction. Also, an additional line (approx. 25 km long) between Kuyubaşı and Esenboğa International Airport is in the planning stages and would make up the next phase of expansion of the metro.
