TCDD started the construction of the high-speed rail line between Ankara and Eskişehir provinces in 2003. Test trips started on April 23, 2007, and the first passenger flight was made on March 13, 2009. The 245 km Ankara-Eskişehir line reduced the travel time to 1 hour and 25 minutes. It is foreseen that the Eskişehir-Istanbul part of the line will be completed in 2013. When the line is connected with Marmaray in 2013, it will be the first daily line in the world between Europe and Asia. The TCDD HT65000 models used in the Ankara-Eskişehir line were produced by the Spanish Construcciones y Auxiliar de Ferrocarriles (CAF) company and consist of 6 wagons as standard. A train with 12 wagons can be obtained by combining the two sets.
The foundation of the Ankara-Konya high speed train line was laid on July 8, 2006, and rail laying started in July 2009. Trial voyages started on December 17, 2010. The first passenger flight was made on August 24, 2011. Of the total 306 km line, 94 km between Ankara and Polatlı were built within the scope of Ankara-Eskişehir project. A line suitable for a speed of 300 km / h was built.
