The Ankara-Istanbul high-speed railway (Turkish: Ankara-İstanbul hızlı tren hattı), is a 533 km (331 mi) long high-speed railway currently running between Ankara and Pendik (a suburb of Istanbul), with the Pendik-Central İstanbul part under construction.

History[edit]

The planned Turkish High Speed Rail Network.

Construction on the route is taking place in two phases. The first phase is a 251 kilometres (156 mi), $747 million route between Sincan (a district of Ankara) and İnönü, for which construction began in 2003 on a segment between Esenkent and Eskisehir; this segment was completed in 2007.[1] Regular service between Ankara and Eskisehir began on 13 March 2009.[2] Two shorter lines complete the first phase: a line between Eskisehir and Inonu began construction in 2008 and was completed in 2010, while a line between Sincan and Esenkent was built in 2008.[1]

The second phase, between İnönü and Pendik, is about 214 kilometres (133 mi) long, and costs $2.27 billion.[1] The substantially higher price of the second phase is due to more challenging terrain than the first, including 33 bridges and 39 tunnels.

The section between Inonu and Pendik (a suburb on the Asian side of Istanbul) was finally opened by the Prime Minister on 25th July 2014, with the service between Istanbul (Pendik) and Ankara taking 3.5 hours. The service has started with 6 departures every day in both directions.[3] The line will continue into central Istanbul when the Marmaray project is completed in 2015. For supporting access to trains until then, a number of public transport services are organized.[4] Since high speed line is not fully completed, the high speed trains will use conventional line in some parts of the route for a while. The line is planned to be completed fully in 2016, and the total budget is expected to reach to 8,8 billion TL. [5]

Construction is partially financed through foreign sources, including €1.25 billion from the European Investment Bank and €120 million from the European Union.[6]

The China Railway Construction Corporation and the China National Machinery Import and Export Corporation won the bid in 2005 to build the railway line in partnership with two Turkish companies, Cengiz Construction and Ibrahim Cecen Ictas Construction. The project was financed in part by a $750 million loan granted to Turkey by China.

Infrastructure[edit]

Turkey ordered ten TCDD HT65000 six-car trainsets from CAF, the first one of which arrived in Turkey in 2007.[1][7] They began service operating between Ankara and Eskisehir, expanding operations as additional high-speed trackage was completed.[1]

Alcatel won an $80 million contract to supply signalling services on the line, as well as interlockings and control systems,[1] while Thales Group has been contracted to supply an ETCS train control system for the Sincan—Eskisehir portion of the route.[8]
