Marmaray, the 13.6-km (8.5-mile) rail
connection between European and Asian
Istanbul via a tunnel beneath the Bosphorus, joins the stations at Kazlıçeşme, Yenikapı and Sirkeci in Europe with the stations at Üskudar and Ayrılık Çeşmesi in Asia—makes it possible to cross from Old Istanbul in Europe to Üsküdar in Asia in a matter of minutes.
Here's a map of the center of Istanbul's rail transit system showing the Marmaray stations. (Click on the map to enlarge it.)

The underground stations at Kazlıçeşme, Yenikapı, Sirkeci, Üsküdar,
and Ayrılık Çeşmesi make it easy for Marmaray passengers
to connect to Istanbul's Metro, city bus, tram and ferryboat networks.
Hour of Operation
Marmaray begins running at 06:00 am. Trains run every 5 to 10 minutes during most of the day, every 15 to 20 minutes late at night. (On Sunday and holidays, trains run every 10 minutes all day.) The last trains run at 24:00 (12:00 midnight).
Fares for the Marmaray are the same as for Istanbul Metro lines. and, as with the Metro, ferries and other modes of transport, paying by Istanbulkart saves you nearly half the full fare. Children up to 5 years old ride free. Those 6 and older must pay the fare. More...
The old suburban trains (banliyö trenleri) on the
European and Asian shores have been stopped to allow their routes to be integrated into the new Marmaray (MAHR-mah-RYE) system. Service on these routes—west beyond Yenikapı and east beyond Ayrılık Çeşmesi—will be opened at sometime in the future so that trains can travel all the way to Halkalı on the European side of the Bosphorus and Gebze on the Asian side.
