High speed trains are connecting Ankara, Istanbul, Konya, Eskisehir, Izmit, Bilecik and Karaman with a speed up to 250 km/h.
HSTs run with lower speed on city passes, shared lines with other type trains and temporary lines due to engineering works.
High speed trains are popular and tickets are sold out very fast. It would be good to buy the ticket in advance. Tickets are on sale 15 days prior to departure. Online ticket is available.
