History

Construction of the first railway line in Turkey began in 1856, being constructed by a British company that had gained permission from the Ottoman Empire. Later, French and German companies also constructed lines - the motivation was not only economic, the region had a strategically important position as a trade route between Europe and Asia.

As with other countries, rapid expansion followed; by 1922 over 8000 km of lines had been constructed in the Ottoman Empire.In the Ottoman Empire: some parts of lines extending into the middle east would not be incorporated into the Turkish State on its creation At the birth of the Republic of Turkey in 1923, there were 3,660 km of standard gauge lines, of which 1,378 km were state-owned; while the lines owned by foreign investors were eventually nationalized starting from 1927. The railways were considered an essential part of the state by the government of the Republic, and continued to expand with new railway projects - over 3000 km of new tracks were built in Turkey between 1923 and 1940. Railways were constructed serving mines, agriculture, people and ports; at the same time more lines serving eastern Anatolia were built, in their part helping to tie Turkey together as a functioning state.

In the years following World War II, the emphasis in transportation shifted to asphalt road and highway construction; it was not until the end of the 20th century that railways returned to favour with major passenger infrastructure projects being initiated, and five thousand kilometres of new lines planned for construction.

Future restructuring

The Turkish State Railways (TCDD) may be split with the passenger and freight operations being part of a new company named DETAŞ (Demiryolu Taşımacılığı Anonim Şirketi, meaning Railway Transport Company) with TCDD left as a track and infrastructure operator. This restructuring will also allow other rail operators to run trains on TCDD tracks by means of track access charges, and will end the monopoly of TCDD.

Network

In 2008, Turkey had 10,991 km of railway lines, of which 95% were single-tracked8697km of lines, 21% of the network was electrified and 28% signalled. Due to the mountainous geography of the country, the network has many steep gradients and sharp curves.

Urban transport

Trams have operated in Istanbul since 1872, first being pulled by horses, and after 1912 by electric power. The system was run by the Dersaadet Tramway Company during the Ottoman period. In the 1960s, trams were removed from the streets of Istanbul in favour of wheeled vehicles such as buses and trolleybuses. However, the decision for returning to rail-based transportation solutions was made in 1985 by the Istanbul Metropolitan Municipality, and in 1988 Istanbul Ulaşım was created as a subsidiary.
