interlocking systemAlstom has completed and put into service the interlocking system of five sections on Eskisehir-Kutahya-Balikesir line in Turkey, totalling 182 km.

All the interlocking system works included the telecommunications and traffic control centre (CTC). The project of 328-km long mainline signalling project work is continuing with the target to open the whole line by end 2021.

“We are extremely happy as we have reached such a significant milestone in this project that is very important to equip the railway network of Turkish State Railways Administration (TCDD) with the cutting-edge technology solutions to improve the safety and efficiency of the line operations, and increase the travel experience of passengers,” Mama Sougoufara, Alstom Middle East and Turkey Managing Director, said.

Alstom will extend the signalling system of the Eskisehir – Balikesir line with the EU standards through the ERTMS and to increase line’s safety by installing the high safety technologies such as Automatic Train Supervision (ATS) system.

In 2011, TCDD awarded Alstom a EUR 89 million contract to supply signalling and telecommunications systems on the line connecting Eskişehir, about 260 km East of Ankara, to Balıkesir near the Aegean coast. The contract covered the design, manufacturing and supply of the complete trackside Atlas signalling system based on level 1 & 2 of ERTMS/ETCS, the Smartlock interlocking solution and Iconis, an integrated control centre. Alstom had to supply level crossing systems, technical equipment buildings as well as power distribution and uninterrupted power supply systems. ERTMS/ETCS on-board equipment, together with local on-board Automatic Train Stop (ATS) device also was included on 27 TCDD locomotives.
