After the railway transportation network are the most used highways in Turkey. This is due to the fact that there is a connection with the highest number of settlements in the inner parts after the highway. Railways have an important place in freight transportation, especially inland. In Turkey, the first railway line was built by the British in İzmir-Aydın. Later on, the railways were built by foreign companies belonging to Germans especially during the Ottoman period. The total length of railways was his 1866 km of foreigners at the time of establishment of the Republic of Turkey.
In the thirty years after the foundation of the Republic, 4000 miles were built. After 1950, the construction of the railway has been suspended. However, according to TCDD data, in 2014, the length of the railway has reached 12.485 km with side lines. maintenance of railways in Turkey are carried out by the General Directorate of Railways construction and repair işleridevlet. earth in the extension of the railways in Turkey have a decisive impact on the way. In our country, most of the railway lines are in east-west direction. The North Anatolian and Taurus Mountains rising along the coast make the railway construction difficult.
Mersin and Iskenderun; In the coastal part of the Black Sea, Samsun and Zonguldak are the provinces with rail connections to other regions through Central Anatolia. Aegean, Marmara and Central Anatolia are the places where the rail network is the highest. The railways in these regions follow the river valleys and depressions.
One of the reasons of the railway network in Turkey is not limited to economic conditions. Because important investments are required for railway construction. Although the landforms are rugged, the railway line length and quality are high in economically strong countries. For example, the rugged landforms and facial measurements of railways in Japan, which is close to half of Turkey face measuring a length of about 24.000 km. High-speed trains are also available in this country.
Switzerland is the most important example. Turkey nodes in the Alps and covering areas up to 5% of the country's surface, has approximately 9 thousand km long railway network. The railways in this country pass through the mountainous areas of the 2000-3000 m height. In this case, the length and quality of railway in Turkey has not only limited to natural conditions, shows that the impact of economic factors.
In our country, railway, coal, copper and oil, as well as raw materials and the transportation of agricultural products are being utilized significantly. However, railways have remained behind the highways in terms of quality and speed. In recent years, some studies have been carried out for the modernization of railways. Renovation of the old locomotives, roads and wagons, some routes being made into two lines, Ankara-Konya, Konya-Eskisehir-Istanbul (Pendik), and Ankara-Eskisehir-Istanbul (Pendik) high-speed train services are some of these studies.
