Ineco, the Turkish company UBM and the consultancy Mott McDonald have been awarded the tender to supervise the modernisation of the railway line that operates between Samsun and Kalin. The rail line that runs from the Port of Samsun, on the Black Sea, to the city of Kalin is one of the six railway lines chosen in Turkey to improve connections between the Mediterranean and the Black Sea, to encourage regional transport development and to reduce the rate of road accidents.

Although it is not currently operational, this single-track, non-electrified line reaches a length of 378 kilometres. The updates to be carried out will afford this rail line the electrification and signalling needed to both reduce travel times and increase train frequency. The project entails monitoring and controlling modernisation of the infrastructure, the superstructure and railway line installations. The work to be carried out includes track extensions, tunnel restorations, improvements to platforms and stations, and new signalling systems and safety equipment, among others.
