The Adana–Mersin Main Line is a 67 km (41 miles) long double track rail line from the Adana Railway Station in Adana to the Mersin Railway Station in Mersin. The line passes through the city of Tarsus and has branch lines to the Port of Mersin. The line is one of the busiest rail lines in Turkey with 57 passenger trains and about 20 freight trains daily.
At Yenice, between Tarsus and Adana, the main railroad line north to Ulukışla to the north joins the Adana–Mersin line; at Ulukışla, its two branches continue to Konya and Ankara to the northwest and Kayseri to the northeast.
On January 20, 1883, the Ottoman Government gave a concession to develop railways in Cilicia to two Turkish men. They sold a part of their rights to a group of English and French investors, leading to the establishment of the Mersin–Tarsus–Adana Railway (MTA), a French company headquartered in London. The line was quickly built and opened on August 2,
