# Yenikapı Transfer Center

Yenikapı Transfer Center (Turkish: Yenikapı Aktarma Merkezi), referred to as Yenikapı, is an underground transportation complex in Istanbul. It is located in south-central Fatih in the neighborhood of Yenikapı, hence the name of the hub. The complex is right next to the Yenikapı railway station serving the T6 light rail line and a short walk away from the Yenikapı Ferry Terminal and İDO ferry service. Yenikapı complex links two stations of Istanbul Metro to a railway station of the Turkish State Railways on the trans-Bosphorus Marmaray tunnel. Yenikapı is the largest rapid transit station in Turkey.

## History

Construction of the Marmaray project started at Yenikapı in May 2004. The new Yenikapı station site was chosen to be just north of the existing railway station and would be built underground as part of the trans-Bosphorus tunnel. Yenikapı was expected to be completed in December 2009 but due to archaeological findings at the construction site delayed the project by four years. In 2008 plans to extend the M2 and the M1 lines south were finalized and Yenikapı was chosen as the southern terminus. Construction of the M2's southern extension started in January 2009 with the Golden Horn Metro Bridge across the Golden Horn. The project was expected to open in August 2010, but due to delays it wasn't opened until 2014. The Marmaray section was the first part of the complex to open, entering service on 29 October 2013. The M2 section opened on 15 February 2014, followed by the M1 section on 9 November 2014.

## Marmaray platform

The Turkish State Railways (TCDD) services Yenikapı via an island platform on the trans-Bosphorus Marmaray rail tunnel. This portion, opened on 29 October 2013, was the first part of the complex that was opened to the public. Trains run between Kazlıçeşme (west of Yenikapı) and Ayrılık Çeşmesi (east of Yenikapı, on the Asian side) within 10-minute intervals. Once the rehabilitation of the existing rail lines are complete, Marmaray commuter service will run west to Halkalı and east to Gebze. This service is expected to commence in 2016.
Construction of the Marmaray tunnel started in 2004 and was expected to open in April 2009. However, due to several important archaeological discoveries at Yenikapı, the opening was delayed until October 2013.
Yenikapı saw 1.4 million boardings in February 2017, making it the busiest station on the Marmaray system as well as making up 29% of all passenger boardings on the line.
