State Railways is changing the Ankara-Istanbul high speed train project. With the change in the project, which is targeted to be raised by the end of 2013, the travel time between Ankara and Istanbul will be shortened by 10 minutes to 3 hours, and the length of the line will decrease from 533 km to 523.
A mandatory change is made in the second phase of the High Speed Train (YHT) project, which will reduce the travel time between Ankara and Istanbul to 3 hours and 10 minutes. In the current project, Arifiye is bypassed on the line where the 33,5-kilometer 'Geyve-Doğancay-Arifiye-Sapanca' route is followed after Eskişehir and Pamukova. Thus, while the line is shortened by 10,5 km, after Geyve, 22 thousand 900 meters of tunnels and viaducts are followed to Sapanca. Below the change; The fact that YHT will reduce its speed up to 80 km on the 'Geyve-Doğancay-Arifiye-Sapanca' route. State Railways (TCDD) also does not want the high-speed train to drop up to 80 km in this location. He wants to overcome the problem by building tunnels and viaducts. With the change, the travel time between Ankara and Istanbul will be reduced by 10 minutes to 3 hours, and the length of the line will decrease from 533 km to 523 km.
TCDD officials went on to tender on February 22,9 for the construction of a 21-kilometer tunnel and viaduct, known as the 'Doğançay Ripajı'. Three consortiums of Turkish and foreign partnerships were offered to the tender. The winning company will deliver the construction in 3 months. TCDD is trying to train Ankara-Istanbul high speed train trains to the end of 21. In order to raise the line of 2013 thousand 2 people to the mentioned date, 62 shifts work 3 hours a day. The infrastructure works of the Eskişehir-Istanbul stage, which consists of two sections: 'İnönü-Vezirhan', 'Vezirhan-Köseköy', was 24 percent in İnönü-Vezirhan and 65 percent in Vezirhan-Köseköy. Superstructure and electromechanical works started and the first rails of 70 kilometers were laid.
The court delayed the second stage 3 years
While the "Ankara-Eskişehir" and "Eskişehir-Istanbul" stages of the high-speed train project were aimed to start and complete the construction work simultaneously, the calculation at home did not fit the market. The company, which lost the tender, applied to the judiciary and TCDD was found right in the court 3 years later. The second phase of the project, Eskişehir-Istanbul, was tendered in two sections on 8 August 2005. The Chinese CRCC-CMC-Cengiz Insaat-Ibrahim Chechen joint venture group won the tender by bidding $ 1,27 billion. However, Yapı Merkezi has applied to the Public Procurement Authority (PPA) by objecting to the 'reduction' method, which is based on the evaluation of financial offers in the tender. The court process started with the acceptance of the application by the JCC. JCC, which found Yapı Merkezi right, canceled the tender and decided to take corrective action. The joint venture group that won the tender applied to the administrative court for the suspension of the execution of the decision of the PPL and for annulment. Examining the tender for the İnönü-Vezirhan section of the 2nd stage, the 3rd Administrative Court found the TCDD's decision on the tender justified and suspended the execution. Examining the tender, the 9th Administrative Court found TCDD's decision unfair and rejected the request for a stay of execution. The consortium carried the different decision of the two courts to the regional administrative court. After the examination, the court found the TCDD's decision on the tender and suspended the execution of the decision of the KİK. TCDD signed a contract with the joint venture group in 2006. Meanwhile, the 3rd and 9th Administrative Courts started to discuss the case on the merits. The courts insisted on their previous decisions. During this time, the joint venture group and the JCC applied to have the case heard at the Council of State. The Council of State made the final point on February 18, 2009 and found TCDD right.
