The Turkish State Railways own and maintain all public railways in Turkey. This includes railway stations, ports, bridges and tunnels, yards and maintenance facilities. In 2016, TCDD controlled an active network of 12,532 km (7,787 mi) of railways, making it the 22nd-largest railway system in the world. Apart from railway infrastructure, TCDD also owns several rail transport companies within Turkey as well as a 50% share of the İzmir-area commuter rail system, İZBAN.
Prior to 2017, TCDD also operated all railways in Turkey. However, with the government taking steps to privatise some of the Turkish railway network, TCDD Taşımacılık was formed on 14 June 2016 to take over all railway operations. Handover of rolling stock was signed on 28 December of the same year and TCDD formally ceased all railway operations on 31 December 2016.[3]
