The Yüksek Hızlı Tren or YHT (English: high-speed train) is the Turkish State Railways high-speed rail service currently operating on two routes; Ankara to Eskişehir with construction under way to İstanbul and Ankara to Konya, which opened in August 2011. YHT uses the HT65000 EMU sets with tilting technology built by CAF. YHT is the only high-speed service in Turkey and in the Middle East operating at speeds up to 250 km/h (160 mph). The YHT operates on the Istanbul-Ankara High Speed Rail Line (only Eskişeir-Ankara part is in operation) and, recently, the Ankara-Konya High Speed Rail Line via Polatlı. Before the YHT came into operation, average journey time between İstanbul and Ankara was 7 hours and 30 minutes. By transferring from the YHT to regional trains at Eskişehir, average journey time between İstanbul and Ankara has fallen to 5 hours and 30 minutes. When the high-speed line is completed to İstanbul, the average journey time is expected to be lowered to 3 hours. Also with service between Ankara and Konya, travelers now have a direct route between the two cities. YHT is the Turkish State Railway's premier route, with 11 trains daily in both directions, although it is only the fourth-busiest route in Turkey. The Yüksek Hızlı Tren is the 8th high-speed rail service in world and the sixth in Europe.
