History of Marmaray
Marmaray is a modern, high-capacity railway system that connects the European and Asian sides of Istanbul with a single line. With a 76.6 km railway and 43 stations, the project provides rail transportation through the immersed tube tunnel built under the Bosphorus.
The idea of building a railway tunnel beneath the Bosphorus was first proposed in 1860. At the time, however, the available technology was not sufficient to realize such a detailed project. The concept was reconsidered over the following decades, but it remained only an idea for many years. As Istanbul’s population grew and traffic problems increased, the project was revived and re-evaluated with modern engineering possibilities.
Marmaray entered public service on March 12, 2019, and became one of the most preferred means of public transportation in Istanbul, with an average of 136,000 daily passengers.
