Why did the high-speed train's route change?

The High Speed ​​Train project is changing the route between 'Geyve-Sapanca' so that the speed does not decrease.
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 being made in the second stage 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, after the Eskişehir and Pamukova, 33,5 kilometers of 'Geyve-Doğancay-Arifiye-Sapanca' route is followed and even Arifiye is bypassed. Thus, while the line is shortened by 10,5 km, following Geyve, 22 thousand 900 meters of tunnels and viaducts are followed to reach Sapanca.

The reason for the change is that YHT has to reduce its speed up to 80 km along the 'Geyve-Doğancay-Arifiye-Sapanca' route.

According to the news of Zaman Newspaper, TCDD does not want the high speed train to drop to 80 km at this location. He wants to overcome the problem by building a tunnel and viaduct. With the change, 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 km.

TCDD officials went out to tender on February 22,9 for the construction of a 21-kilometer tunnel and viaduct, known as the 'Doğançay Ripaj'. Three consortia, consisting of Turkish and foreign partnerships, submitted bids for the tender. KazanThe company will deliver the construction in 21 months. TCDD is trying to train Ankara-Istanbul high-speed train services by the end of 2013. 2 thousand 62 people work 3 hours in 24 shifts in order to reach the mentioned date. The infrastructure works of the Eskişehir-Istanbul phase, which consists of two sections, 'İnönü-Vezirhan' and 'Vezirhan-Köseköy', were completed at a rate of 65 percent in the İnönü-Vezirhan section and 70 percent in the Vezirhan-Köseköy section. Superstructure and electromechanical works were started and the first 14 kilometers of rails were laid.

While the Ankara-Eskişehir and Eskişehir-İstanbul stages of the high-speed train project, which consists of two parts, are intended to start and be completed simultaneously, the account at home did not fit into the bazaar.

The company, which lost the tender, applied to the judiciary and TCDD was right in court 3 years later. The second phase of the project, Eskişehir-Istanbul, was tendered on 8 August 2005 as two sections.

However, Yapı Merkezi appealed to the Public Procurement Authority (KİK) by objecting to the 'reduction' method, which is used as a basis for the evaluation of financial offers in the tender. The court process started with the KİK's acceptance of the application.

Finding Yapı Merkezi right, the JCC canceled the tender and decided to take corrective action. tender kazanOn the other hand, the joint venture group applied to the administrative court for the stay of execution and annulment of the decision of the GCC. The 2rd Administrative Court, which examined the tender for the İnönü-Vezirhan section of the 3nd stage, found TCDD's decision on the tender justified and stopped the execution. The 9th Administrative Court, which examined the tender, found TCDD's decision unfair and rejected the request for a stay of execution. The consortium brought 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 fundamentally. Courts insisted on previous decisions. During this period, the joint venture group and the JCC applied for the case to be heard at the Council of State. The Council of State put the last point on February 18, 2009 and found TCDD justified.
