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 İnönü began construction in 2008 and was completed in 2010, and a line between Sincan and Esenkent was built in 2008.[1]
