HistoryEdit

A plan to build a subway line on the Asian side of İstanbul was approved in 2005. In 2008, a €751 million construction contract was awarded to a consortium of Astaldi, Makyol and Gülermak. The rolling stock was ordered from the Spanish company CAF.[7] In mid-2010, the construction of the tunnels was completed and the track laying started. The route has connections with TCDD's Marmaray system at Ayrılıkçeşmesi and the İstanbul Metrobus system at Ünalan. Scheduled opening date was December 2011 up to Kartal, however it was postponed due to signalization works.[8]

StationsEdit

The M4 has a total of 19 stations in operation, with 4 more under construction.
