Turkish State Railways (TCDD) will initially operate six round trips a day using its fleet of 250km/h trains supplied by CAF, Spain. TCDD has also purchased a fleet of seven 300km/h eight-car Velaro trains from Siemens for operation on the route.
Ankara – Istanbul YHT high-speed trains will have four classes of accommodation: business plus, business, economy plus and economy, and TCDD plans to offer a range of discounted fares to encourage people to use the new service. Train services between Eskişehir and Istanbul were suspended during the construction of the high-speed, so TCDD will have to build the traffic from scratch. Nevertheless TCDD is looking to carry 7.5 million passengers a year and to gain a 78% market share.
The $US 4bn project has been completed in phases. The Ankara - Polatli – Eskişehir section opened in March 2009, followed by Polatli – Konya in August 2011. A through service from Konya to Eskişehir was introduced in 2013.
The Ankara – Istanbul high-speed line has 31 tunnels totalling 40.8km, the longest of which is 4145m. There are 27 viaducts totalling 14.55km, plus 52 bridges.
TCDD is currently building four more high-speed lines: Ankara – Sivas (405km), Sivas – Erzincan (235km), Bilecik – Bursa (106km), and Polatli – Izmir (527km).
