First test train through the Marmaray tunnel

06 Aug 2013


TURKEY: A ceremonial first test train ran through the Marmaray tunnel between Kazliçesme on the European side of Istanbul and Ayrılıkçesme on the Asian side on August 4, with Prime Minister Recep Tayyip Erdogan at the controls. 'This project is not the project of the century, but it is the project of centuries', said Erdogan.

The Prime Minister was joined on the train by Minister of Transportation, Maritime Affairs & Communications Binali Yıldırm and Mayor of Istanbul Kadir Topbas.

Inauguration ceremonies for both the Marmaray tunnel and the high speed line between Eskisehir and Gebze to the east of Istanbul are scheduled for October 29, the 90th anniversary of the founding of the Turkish republic.

While the 1·4 km immersed tube tunnel is scheduled to open this year, work to upgrade existing lines to provide a metro-styles suburban service over a 77 km cross-city route is not expected to be completed until June 2015.

The Marmaray project was described in detail in the May 2013 issue of Railway Gazette International, which subscribers can access in the digital archive.

Turkey to unveil Bosphorus rail tunnel that joins two continents

AFP | Oct 29, 2013, 11.20 AM IST

Turkey is due to unveil on Tuesday a three-billion-euro rail tunnel under the Bosphorus connecting Istanbul's European and Asian sides, one of several mega projects driven by the Islamic-rooted government in the country's main gateway city.

The 13.6-kilometre (8.5 miles) tunnel includes an immersed tube tunnel which government officials say is the world's deepest at 60 metres (nearly 200 feet) below the seabed.

The inauguration of the ambitious project that has cost an estimated three billion euros coincides with the 90th anniversary of the founding of modern Turkey.

"Turkey will celebrate two feasts together," transport minister Binali Yildirim said earlier this month.

"We will mark the 90th anniversary of the republic on October 29 and also realise a one-and-a-half century dream of a major rail tunnel project in Istanbul," he said.

The tunnel is part of a larger "Marmaray" project that also includes an upgrade of existing suburban train lines to create a 76-kilometre (47-mile) line that links the two continents.

The idea was first floated by Ottoman sultan Abdoul Medjid in 1860 but technical equipment at the time was not good enough to take the project further.

However the desire to build an undersea tunnel grew stronger in the 1980s and studies also showed that such a tunnel would be feasible and cost-effective.

Prime Minister Recep Tayyip Erdogan, a former mayor of Istanbul, revived the plan in 2004 as one of his mega construction projects for the bustling city of 16 million people -- which also include a third airport, a third bridge across the Bosphorus and a canal parallel to the international waterway to ease traffic.

His ambitions were one cause for the massive anti-government protests that swept the country in June, with local residents complaining that the premier's urban development plans were forcing people from their homes and destroying green spaces.

Japan's Prime Minister Shinzo Abe will be present at the official opening, as the Japan Bank for International Cooperation was the main financier contributing 735 million euros ($1 billion) to the project.

Construction of the tunnel, labelled the "project of the century" by Erdogan's government, started in 2004 and had been scheduled to take four years but was delayed after a series of major archaeological discoveries.

Some 40,000 objects were excavated from the site, notably a cemetery of some 30 Byzantine ships, which is the largest known medieval fleet.

But these unexpected finds eventually frustrated Erdogan, who complained two years ago that artefacts were trumping his plans to transform Istanbul's cityscape.

"First (they said) there was archaeological stuff, then it was clay pots, then this, then that. Is any of this stuff more important than people?"

Transport is a major problem in Istanbul, and each day two million people cross the Bosphorus via two usually jammed bridges.

"While creating a transportation axis between the east and west points of the city, I believe it will soothe the problem... with 150,000 passenger capacity per hour," said Istanbul's mayor Kadir Topbas.

Marmaray tunnel opens to link Europe with Asia

29 Oct 2013


'This project that was dreamed of 153 years ago, has been realised' said President Abdullah Gül as he inaugurated the Marmaray tunnel between the European and Asian sides of Istanbul on October 29, as part of the Republic Day celebrations marking the 90th anniversary of Atatürk's proclamation of the Turkish Republic.

Guests at the opening of the 'project of the century' included Romanian Prime Minister Victor Ponta and Somalian President Hasan Sheikh Mahmud. Also present was Prime Minister Shinzo Abe from major funding partner Japan, who ambitiously suggested that the line could one day form part of a rail route from Tokyo to Istanbul and London.

Initial operations will be limited to metro-style services on the core tunnel section of the route, including 4 min journey through the immersed tube under the Bosporus between Sirkeci and Üsküdar. Work is still underway to upgrade the suburban railways at either end of the tunnel, with trains expected to run over the full 76·3 km between Halkal? and Gebze from mid-2015.

Plans for a tunnel across the Bosporus were first developed during the reign of Sultan Abdülmecid in 1860, and the scheme was revived on a number of occasions. A comprehensive study in 1987 established that the project was feasible and selected the alignment, including the 1·4 km immersed tube tunnel said to be the deepest in the world at 60 m, and 12·2 km of mainly bored tunnel with four underground stations.

Turkey and Japan International Cooperation Agency signed a financing agreement in 1999. Preparatory works began in 2001 and construction of the tunnel in August 2004, with the immersed tube completed in February 2009. Works at Sirkeci station were delayed by significant archaeological discoveries.

The Marmaray project was described in detail in the May 2013 issue of Railway Gazette International. Read the article free of charge.
