The Gebze-Halkali train line was opened on March 12 by Turkish President Recep Tayyip Erdogan.
The Gebzi-Halkali train line is 76.6 kilometers long, after the introduction of the 13.6-kilometer Marmaray line which is linking the Asian and European sides of Istanbul. The Infrastructure Investments General Directorate of the Transport and Infrastructure Ministry completed the opening of the remaining 63 kilometers, as a result, the journey from end to end is reduced from 185 minutes to 115 minutes.
The new railway will provide service to the western suburb of Halkali and from the east the Gebzi district in Kocaeli province on the Istanbul border. While the Marmaray line has been connecting, since 2013, three stations from the European section with two stations from the Asian section of Istanbul.

The suburban process on the subway meter can be achieved at two-minute intervals. The third line in the south will be used by passenger and freight trains between trains and high-speed trains. A total of 10 units have been built to ensure the two-way express train runs on this line.
