The journey from Mersin to Istanbul is serviced by conventional trains primarily operated by TCDD, Turkey's state rail operator. One of the leading services on this route is the Intercity train, which achieves speeds of around 160 km/h (99 mph). This train covers the distance between Mersin and Istanbul in approximately 8 to 10 hours, depending on the particular service and stops made along the way. Travelers can expect comfortable seating and access to basic amenities like dining options and power outlets.
For those who prefer a faster alternative, the Yüksek Hızlı Tren (High-Speed Train) currently operates partial routes connecting Mersin with key cities along the way, although a direct high-speed line from Mersin to Istanbul is still under development. If available, this high-speed train could cut down travel time significantly, so checking the latest schedule and service announcements is recommended.
