Marmaray is a danger: Marmaray, the first lik feasibility reports, based on 1987, Halkalı- A gigantic transportation project that will provide access by rail between Gebze and pass through the boğ tube passage -.
The foundation of 9 May 2004 was laid and the phase between ılık Ayrılıkçeşme-Kazlıçeşme was opened in 29 October 2013.
The construction of other stages continues.
Archaeological remains during construction; 36 appeared in ships, harbors, tunnels, royal tombs and various historical artifacts.
While traveling from Izmit to Istanbul, I sometimes get on the Metro from Kartal. Passing under the Bosphorus with Marmaray worries me and KadıköyI go down to Bakırköy by taking the sea bus. I also realized that I was not alone in this anxiety! Many co-friends, that tube is worried about the transition!
Some time ago, when I saw the news that Marmaray derailed and that the passengers had to walk in the tunnel, my concerns increased a bit! In the statement; The reason for gösteriliy technical failure ç was shown.
The interesting thing is; Üsküdar Municipality Council Member and Civil Engineer Nezih Küçükerden made a statement and said; I The project was in a hurry! There are mistakes in project and application. The error must be found and resolved. Otherwise, such problems will happen again! Tür
Remember, Marmaray 29 was the first accident after a day of service in October 2013! Short-term power was cut off and the tram on the run was derailed!
Meanwhile, an allegation about Marmaray on the internet has raised concerns yet!
In summary; De Geological deformations were encountered in the immersed tube of the 1600 meter long, which has been known for months. Although the contractor repeatedly warned the company, this event is hidden from the public. Due to the mobility of aluvion and marine sediments in the submerged tube pathway, a large curvature has been found although it has not yet reached the breaking point. This has caused the conveying device to derail from the rails as it has also been transferred to the rails inside the pipe. Bu
This is a terrible claim!
The curving of the boat passing under the throat, even a few inches from the seat is a disaster!
The common opinions of experts who know the technical aspect of the work; ”This work has been rushed through election accounts! Y Such projects have a process of completion under normal conditions, and if you limit this time, disasters are inevitable!“
In my mind, the Prime Minister of the time at the groundbreaking ceremony of the Bay Bridge, Erdogan, the contractor with the contractor to negotiate the delivery time of business!
I can't cross that bridge any more!
All of them aside; The claims are serious and of great concern. It is useful to respect the opinions and suggestions of experts.

Mr. Kupcu, the information you have used in your article is entirely hearsay and rumors that will cast a shadow on the beauty of the project. As an engineer working in the Marmaray Project, I can say that; The scene of the last incident is the region between Ayrilikcesme and Uskudar, which has no direct relation with the batirmatup tunnels. The immersion tube tunnels are made with the latest technology and designed against an earthquake of 7.5 magnitude. As the reason for the event
If the periodical maintenance-repair work should not be done sufficiently
It can be shown.
A second point is, as you mentioned in your article, you have shown as an example of the fact that Marmaray was put into service immediately, there was an accident, the electricity was cut and the tramway on the expedition derailed. First, we need to separate the apples and pears from each other. It is not a tramway vehicle used in Marmaray, but a metro vehicle. Secondly, the electricity was not cut as a result of the accident and the vehicle was not derailed in that incident. There was only a power outage in the incident. Such situations can be experienced all over the world on newly opened lines. Due to the nature of rail systems, it takes time for a newly opened railway system to work fully with all coordination, and this situation has been scientifically included in the literature by many researchers.
As a result; In this country, the first bridge was opposed, but it was used, it was used against the second bridge, but it was used. Marmaray was called a bad project, but it is strange that 130 million passengers have been carried since its opening. Now they are against the third bridge, but don't worry, it will be used as well. These things are always like that. Someone does it, others just talk and look, and the caravan continues to walk. You and others like you continue not to use it, if not a bit of passenger dignity
The citizens who use the other are comfortable.
