Full signalization in Central Anatolia

Several steps have been taken about signalization in this region where the freight traffic is quite busy.

Zonguldak-Irmak railway line

Zonguldak-Irmak railway line has important freight traffic especially due to Kardemir (the steel company) and passenger trains. ETCS Level1 is installed. The renewal of the line and signalization works were also supported by IPA funds.

Samsun-Kalin railway line

Samsun-Kalin railway line was renewed and opened last year after having kept closed for almost 5 years. The signalized line now allows higher speed and has higher capacity. Freight traffic restarted again. Passenger services have not started yet due to Covid-19.
