Tunnel construction is only about 18 kilometres (11 mi) from the active North Anatolian Fault, worrying engineers and seismologists."Since AD 342, it has seen large earthquakes that each claimed more than 10,000 lives." Scientific calculations estimated a probability of 77 percent that, at some time in the next 30 years, the area will suffer an earthquake of strength 7.0 or more on the Richter magnitude scale.In February 2010, Railway Gazette International reported that the tunnel's administrators were hiring consultants to analyse options for carrying freight traffic.Although not officially announced by TCDD, the Prime Minister and officers stated several times that Marmaray will help to bring back the use of the term "Silk Road" with a new name of "Iron Silk Road" by allowing freight trains to move between Europe and China.The project includes a 13.6-kilometre (8.5 mi) crossing of the Bosphorus and the upgrade of 63 kilometres (39 mi) of suburban rail lines to create a 76.6-kilometre (47.6 mi) high-capacity passenger line between Gebze and Halkalı, along with the provision of 440 electric multiple unit cars.The construction contract for the project was awarded to a Japanese-Turkish consortium led by Taisei Corporation in July 2004.On October 29, 2013, the first stage of the Marmaray project, covering the underground connection between Europe and Asia, was inaugurated.
This underwater tube is accessed by bored tunnels from Kazlıçeşme on the European side and Ayrılıkçeşmesi on the Asian side of Istanbul.
It represents the world's deepest undersea immersed tube tunnel.
The second stage is the renewal of current railways on the ground, between Gebze and Ayrılık Çeşmesi on the Asian side, and between Kazlıçeşme and Halkalı on the European side.
It was scheduled to be completed at the same time as the first phase (tunnels and underground parts), but little progress has been made on this and it is still incomplete.
A third line will be added which will provide the electric multiple unit (EMU) cars and other rail cars the ability to move separately.
