Istanbul Haydarpaşa Terminal or Haydarpaşa Terminus is a railway terminal in Istanbul. Until 2012 the station was a major intercity, regional and commuter rail hub as well as the busiest railway station in Turkey. Haydarpaşa, along with Sirkeci Terminal, are Istanbul's two intercity and commuter railway terminals. As of 19 June 2013 all train service to the station has been indefinitely suspended due to the rehabilitation of the existing line for the new Marmaray commuter rail line. The station building however still houses the headquarters for District 1 of the State Railways.The station building, built in 1909 by the Anatolian Railway as the western terminus of the Baghdad and Hedjaz railways, has become a symbol of Istanbul and Turkey and is famous throughout the Middle East.Haydarpaşa is situated on an embankment over the Bosphorus just south of the Port of Haydarpaşa and is slightly north from central Kadıköy. Until the suspension of rail service, ferry service was available to Eminönü, Karaköy and Kadıköy from the station's ferry dock.The closure of the station has been subject to a lot of controversy. As it is unclear if Haydarpaşa will be re-opened to rail service once the Marmaray project is complete, many claim that the Turkish government is planning to sell the historic railway station along with the port and turn it into a residence/luxury resort.
