Alstom has secured signalling contracts for the Bandirma–Bursa–Yenisehir–Osmaneli railway project and the Cekmekoy-Sancaktepe-Sultanbeyli metro line.

Alstom has won two signalling contracts to support Turkey’s General Directorate of Infrastructure Investments (AYGM), and Istanbul Metropolitan Municipality’s in their efforts to upgrade their signalling infrastructure in the country.

The scope of AYGM includes the construction and supply of electromechanical works for the nearly 201km-long Bandirma–Bursa–Yenisehir–Osmaneli (BBYO) high standard railway project.

Alstom, through Kalyon Insaat Sanayi ve Ticaret A.S., will supply Interflo 250 and 450, European Rail Traffic Management System (ERTMS) level 1 & 2, and deploy the entire Interlocking system including Traffic Control Centre (CTC). Additionally, Alstom will install a smart object controller with the system to eliminate obsolescence risks with legacy systems and provides the capability for the line’s signalling systems to interface over modern fibre-based digital networks and GSM-R (railway communications system) to increase reliability, performance, and functionality. At the end of the project, the BBYO line will be fully interoperable to all available trains on the Turkish network.

The second contract with Istanbul Metropolitan Municipality’s Cekmekoy-Sancaktepe-Sultanbeyli (CSS) metro line will include the construction and electromechanical procurement work. Through Dogus Insaat ve Tıcaret A.S., Yapı Merkezı Insaat ve San. A.S., and Ozaltın Insaat Tıcaret ve Sanayı A.S. JV, Alstom will supply, test and commission the entire signalling system of the 11km-long Cekmekoy-Sancaktepe-Sultanbeyli (CSS) metro line, which has the capacity to carry 120,000 passengers/hr, including the supply of wayside equipment for eight stations and on-board systems, and the CBTC signalling for four new trains. These driverless systems will shorten headways between trains by 90 seconds. Digitalisation is key to support sustainable mobility, simply by adding more capacity to the existing infrastructure while further increasing the comfort and safety of rail.

Volkan Karakılınç, Managing Director of Alstom Turkey, said: “I am extremely happy to see the impact of Alstom as a leader of sustainable and innovative mobility in the country. We are honoured to deploy a number of digital-ready technologies that will bring much needed reliability improvements to support traffic levels and deliver greater efficiencies.”
