The initial 10.5km nine-station section of Line M5 connects Yamanevler with an interchange with the trans-Bosporus Marmaray link at Üsküdar.

A consortium of Mitsubishi Corporation and CAF has supplied 21 six-car trains for Line M5 under a €119m contract awarded in June 2014.

The 9.2km second phase from Yamanevler to Çekmekköy is due to open in mid-2018, adding a further seven stations to the network.
