Alstom has signed a contract to provide the Rigid Overhead Catenary System (ROCS) for a portion of Türkiye’s new high-speed railway line between Halkali and Kapikule.
The contract, which was awarded to Alstom by RESA Yapi Elektromekanik A.S., will see the company provide an aerial feeding system along the 14km double-track TBM tunnel, which is set to pass under both residential areas and Lake Küçükçekmece.

Design, production and supply of the ROCS components will be handled by Alstom’s site in Valmadrera (Lecco), with further aid coming from Alstom Algeria for the catenary installation design of the line.
Edoardo Gino, Alstom Valmadrera Site Director, said:We are proud to supply the first Rigid Overhead Catenary System for Türkiye's new high-speed line.
This contract demonstrates not only the excellence and innovative approach of our Site but also recognises our commitment to modernising rail infrastructure globally, supporting to bring Europe even closer to the rest of the world.
The new line between Halkali and Kapikule is set to be part of the Trans-European Transport Network (TEN-T), a 153km line connecting the European Union and offering increases of both 80% in passenger capacity and 45% in freight capabilities.
