M2 Yenikapı - Hacıosman Metro Line

The M2 line, located on the European side of Istanbul, is a metro line extending from Yenikapı to Hacıosman. Thanks to its high capacity, it plays a significant role in urban transportation, serving an average of 500,000 passengers per day.

History and Development

Construction of the line began in 1992, with its opening carried out in phases. The first step was taken on 16 September 2000 with the inauguration of the Taksim–Levent section. Immediately following this, the Levent–4. Levent segment was put into service on 31 October 2000. As part of the second phase, the Taksim–Şişhane and 4. Levent–Atatürk Oto Sanayi sections opened on 30 January 2009. The northern extension was completed with the addition of Darüşşafaka station on 2 September 2010, Seyrantepe station on 11 November 2010, and finally Hacıosman station, the line’s terminus, on 9 July 2011. The southern extension reached its final form with the opening of Yenikapı station on 15 February 2014 and the Vezneciler–İstanbul Üniversitesi station on 16 March 2014.^【1】

Operations and Technical Information

The M2 line is 23.49 kilometers long and has 16 stations. The one-way journey takes approximately 32 minutes. Operating hours are from 06:00 in the morning to 00:00 at night. The line operates with a fleet of 192 vehicles, and on the main route between Yenikapı and Hacıosman, trains run at intervals of approximately 3 minutes and 55 seconds. Additionally, transfers are possible from Sanayi Mahallesi station to the Seyrantepe Mekik Operation, with services on this segment running at approximately 8.5-minute intervals. Most stations are built underground in tunnel structures, with the exception of Haliç station, which is located on a viaduct over the Haliç Metro Bridge.^【2】

Security and Safety Systems

Passenger safety and operational security are top priorities on the M2 line. Scenarios for potential adverse situations have been developed and regularly tested through simulations. All stations are under continuous surveillance via camera systems and security personnel. The line is equipped with state-of-the-art fire detection and suppression systems. All materials used in construction were selected for their resistance to high temperatures and their ability to avoid emitting toxic gases during combustion. In the event of an emergency, a tested and proven smoke control and evacuation system ensures safe passenger evacuation. The line’s signaling, switch, and vehicle systems operate fully automatically but can also be manually operated when necessary. Power supply is provided from two separate sources; in the event both are interrupted, generators activate within 15 seconds to ensure trains reach the nearest station. In the rare case that the generators also fail, lighting and electronic control systems continue to operate uninterrupted for three hours via uninterruptible power supplies (UPS).
