ANKARA - ISTANBUL High Speed ​​Train Project

The High Speed ​​Train Project includes the construction of a new double-line high-speed railway with an all-electric, signal, suitable for 250 km / h independent of the existing line between Ankara and Istanbul.

Today, the total line between Ankara and Istanbul is 576 km, all of which are signal and electrical.

After the completion of the high-speed, double-line, electric and signal-free, high-speed train line, independent of the existing line, 250 km / h, the distance between the two major cities will be reduced to 533 km.

The project 10 consists of separate parts.

• Ankara-Sincan: 24 Km
• Ankara-High Speed ​​Train Station
• Sincan-Esenkent: 15 Km
• Esenkent-Eskişehir: 206 Km
• Eskişehir Railway Station
• Eskişehir-İnönü: 30 Km
• Inonu-Vezirhan: 54 Km
• Vezirhan-Köseköy: 104 Km
• Köseköy-Gebze: 56 Km
• Gebze-Haydarpaşa: 44 Km

44 km 'Lik Gebze-Haydarpaşa section will be transformed into surface metro with Marmaray project and will be realized within the scope of Marmaray Project.

The project also includes 12 high-speed train and high-speed train depot construction.

Ankara - Istanbul High Speed ​​Train Project will be completed in two stages.

The Ankara - Eskişehir section of the project is in operation this year, while the construction works between Eskişehir and Istanbul continue.


• Fast, comfortable and safe transportation between Ankara and Istanbul with double lines, electric, signal and 250 speed.
• To increase the share of rail transport in passenger transportation by% 10 to% 78.
• Reduce travel time between Ankara and Istanbul.


• Increasing the competition chance of the railway in the Ankara-Istanbul line, which is the busiest passenger and cargo axis in terms of road, rail and airway traffic, will increase the passenger share from 10 to 78.
• 7-5 hour by rail, 6-3 hour on the Ankara-Istanbul route, 4,5-XNUMX hourly trip time with the use of service vehicles from the center with the airway;
• Ankara-Istanbul 4-4,5 hours,
• Ankara-Eskişehir is coming to the hour,
• Travel time in Ankara-Izmir line will be shortened
• With Esenkent-İnönü and İnönü-Köseköy in operation at 2008;
• Ankara-Istanbul 3 hours,
• Ankara-Gebze 2 will go down to 30 hours.
• This significant time savings in travel time will make cities the suburb of each other and will offer the opportunity to go to the residents of different cities day by day for compulsory reasons such as education and work.
• Economic, social and cultural interaction between cities will increase.
• It will integrate with Marmaray and provide uninterrupted passenger transportation from Europe to Asia.
• When other high-speed train projects take place, high speed train networks will be formed in the important lines of our country.
• The double-line high-speed train line built separately from the existing line will increase the capacity of the existing line for freight and other trains, and this will reflect positively on other lines.
• The urbanization rate is increasing day by day, and our industrialized country is the fastest train to the modern public transportation vehicle, 21. century, Ç New Railway Age yüz will be an important step.
• Our country, which is in the process of accession to the European Union, will be prepared for this process with its transportation infrastructure.
• The most modern transportation system in public transportation, which is not dependent on petroleum, has a low cost of construction, has a long service life, uses less land than motorways, does not cause environmental pollution, will increase the competitive power and transportation share with the catching of the age; balanced transportation system will make many positive effects from economy to our social cultural life.

As the railways that open in front of the high-speed train age evolve, the Turkish people will know the railway transportation system better and take over it.

Tender of the project's 206 km Esenkent-Eskişehir (İnönü) section 17. 09,1999 was made on 23.11.2000 and a contract was signed with AOG Consortium.

The project was started.

After the 3 annual period, the project was started by starting the groundbreaking ceremony at 08.06.2003 Ankara for the realization of the project.

From Rehabilitation to High Speed ​​Train.

The project has been transformed into a new double-track high-speed train project by maintaining the existing line and from the rehabilitation including the construction of an additional road next to the Current Line.

How was the line constructed?

Construction works of Esenkent-Eskişehir High Speed ​​Line continued in four different sections. In İlören, Biçer and Beylikova, 3 separate construction center was established.

All materials used in the infrastructure, superstructure and electromechanical systems of the project were selected in accordance with international standards. During the construction of the line, in order to determine the ways in which the applications will be solved and the solutions to the problems encountered, cooperation was carried out at every stage with the distinguished universities of our country.

In Spain, rails manufactured for the high speed train line and the materials belonging to the traverse and electromechanical systems coming from abroad were stored in the storage areas.

36 m panels prepared in warehouse areas were even laid out with line assembly machine named VAICAR. Then the line electrification, signaling and telecommunication systems were completed. All necessary works have been completed in order to prepare the line for test drives.
Esenkent- Eskişehir High Speed ​​Line continued parallel to the existing road, but there were also some points. At this point, train underpasses and train overpasses were made and the relation between the existing and high-speed train lines was interrupted.

In addition, the high-speed train line was crossed over the highway as the high-speed train line cut the Ankara-Eskişehir State Highway at 2. The subway, overpass and culvert constructions were made from the agricultural areas and settlements on the route to ensure the passage of pedestrians and animals through vehicles such as road vehicles, tractors, harvesters.

What has been done in Esenkent-Eskişehir ..

· 2,5 million tons of 25 million tons of excavation,
· 164 Million Tire Ballast Moved With 2,5 Bin Truck Load
· 254 pcs,
· 26 Roadway Overpass
13 Piece River Bridge,
· 30 Unit Highway Underpass,
2 Piece Highway Crossing Bridge,
7 Piece Train Bridge,
· 3926 Piece Viaduct with Total 4 Meters
471 m Tunnels were constructed with 1 m length.
· Total 57 Thousand Ton Ray,
· 680 Thousand pieces of traverse.
As a result; The Esenkent-Eskişehir high-speed train line was constructed as a double line with an independent 250 km / h speed.

Speed ​​Train Tests
