There used to be suburban trains running from Haydarpasa to Pendik railway station but as part of the Marmaray project this line is currently out of service (it is expected to reopen in 2018). Since 25 July 2014, high-speed services to Ankara start from this station, pending termination of the upgrades on the line to Istanbul proper. In 2016, an extension of the M4 line of the Istanbul Metro was completed.
