The maximum speed of the trains can go up to 04 km / hour. Ankara-Eskişehir was opened to transportation in 250 and Eskişehir-Istanbul in 2009.

Revisions and incomplete cuts
Arifiye station will be bypassed with Doğançay ripage, since the speed of the high-speed train on the Geyve-Doğançay-Arifiye-Sapanca line will decrease to 80 km / h.

Due to the collapses and landslides experienced during the excavations in Tunel-26 site, the project route was necessarily changed in this area. As of today (19.06.2016), the tunnel is still not opened and its tender is expected to be made for supply works. During this period, the trains switch to the old railway between Tünel-28 and Tünel-27 of the high-speed railway and continue on their way by switching to the high-speed railway again at the point where Tünel-8 is located after about 25 km.

Doğançay ripage
The tender for the Doğançay ripage (22,9 km tunnel and viaduct) was launched on February 21, 2012. The financial envelopes of the companies participating in the tender were opened on March 29, 2012 and were given until the cancellation of the tender because the cost was incredibly large. In this section, trains switch to the old train line in Alifuatpaşa and return to the high-speed railway in Sapanca and continue on their way.

Speed ​​rail and Köseköy connection
The real high-speed railway segment of the project, which is currently partially completed and partially ongoing, ends in Köseköy. The trains use the renewed conventional train line to reach Istanbul. A second project (also called Speed ​​Railway) has been developed for future needs, congestion in Marmaray and for a faster train line. In this project, the maximum speed of the trains is planned to reach up to 350 km / hour, and the route will be Ankara-Ayaş tunnel-Çayırhan-Adapazarı-İzmit (North) -Pendik (North) -Yavuz Sultan Selim Bridge-Third airport-Halkalı It is expected to be in the form. In addition, a connection is envisaged in Köseköy with the existing line.
