Istanbul Metropolitan Municipality awarded Hyundai Rotem a contract in April 2016 to supply 75 four-car trains for the initial 24.5km phase of Line M7 from Mahmutbey to Kabataş. The 1.5kV dc overhead trains are being assembled at the Eurotem facility in Adapazari in northwest Turkey and the contract calls for 50% local content. Eurotem is expected to deliver eight vehicles a month in the run-up to the opening of the 19-station Line M7 in the fourth quarter of this year. In December 2017, a further 20 four-car trains were ordered for the 18.5km extension to Esenyurt.
