Turkish Airlines provides an important network of internal flights from Istanbul, Ankara and Izmir to all of the major Turkish cities. Turkish Airlines flies frequently to 33 cities in Turkey. Turkish Maritime Lines offer several coastal services with their Adriatic Line subsidiary, providing excellent opportunities for sightseeing. Since most voyages are at night, there is little to see. There are also services between Istanbul and Izmir, with overnight accommodation and ferry routes along Turkey's northern Black Sea coast.
Fares are comparatively cheap.
Fares are more expensive for express and mail trains, even though express trains are relatively slow, and some routes are indirect. Top expresses between Istanbul and Ankara are fine, as fast and almost as cheap as the bus. East of Ankara equipment is worse and travel is slow. Steam engines, such as the Anatolia Express , which traverses eastern Turkey, are retained for tourist trains on some routes. Steam engines occasionally haul chartered tour trains, almost always in western Turkey.
