The Ankara–Istanbul high-speed railway (Turkish: Ankara–İstanbul yüksek hızlı demiryolu), 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, and 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 opened by the prime minister on 25 July 2014, with the service between Istanbul (Pendik) and Ankara taking 3.5 hours. The service started with six departures daily in both directions.[3] The line will continue into central Istanbul when the Marmaray project is completed in approximately 2018.[4] Until the high speed line is fully completed, the high speed trains will use conventional line on some parts of the route (between Sapanca and Alifuatpaşa. The line is planned to be completed fully in 2016, and the total budget is expected to reach 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, sections and speeds[edit]

Section Length Max Speed Notes
Ankara Central - Sincan 24 km 140 km/h To be rebuilt as part of the Başkentray project
Sincan - Polatlı 69 km 250 km/h
Polatlı - Eskişehir Central 152 km
Eskişehir Central - Vezirhan 92 km One tunnel is uncomplete making two others unusable and reduicing the speed due to the by-pass
Vezirhan - Köseköy 96 km The section between Alifuatpaşa and Sapanca (~23 km) is still under construction and is by-passed with the existing conventional railway line
Köseköy - Gebze 56 km 160 km/h
Gebze - Haydarpaşa Terminal 44 km 100 km/h Partly under construction as part of the Marmaray project

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.[7]
