Nexans to supply special railway cables to Alstom Transport for Istanbul’s Marmaray trans-Bosphorus rail link

3.3 million Euros contract to supply 1,350 km of specialized signalling and low voltage power cable

Paris, October 8, 2009 – Nexans, the worldwide leader in the cable industry, has been awarded a 3.3 million Euros contract by Alstom Transport to supply specialized signalling and low voltage (LV) power cables for Istanbul’s Marmaray trans-Bosphorus rail link.

Nexans railway cables Axle counterThe agreement covers the manufacture and supply of signalling cables as ZPAU, digicode and eurobalise as well as low voltage power cables K25 compliant with French specifications and local specificities (including EMC and safety criterias). These cables will be manufactured in Europe Nexans factories from now until end 2010, and installed in 2010 and 2011.

One of the world’s current major transportation infrastructure projects

The Marmaray rail link is currently one of the world’s major transportation infrastructure projects. It is scheduled to enter service in 2013, when the 76.3 km line will link Halkali, on the European bank of the Bosphorus (the Istanbul Strait), to the suburb of Gebze, on the Asian bank and will connect with Istanbul’s urban transport network. The link includes an immersed tube tunnel of 1.4 km accessed by a 10 km bored tunnel. With a capacity of 75,000 passengers per hour in each direction, the new link will considerably reduce traffic congestion in Turkey’s biggest city.

The AMD consortium, led by Alstom Transport, is carrying out Phase 2 of the Marmaray project, covering the construction of new lines and the refurbishment of existing ones. As consortium leader, Alstom Transport is responsible for project coordination and general engineering, track installation and electrification and signalling.

Sole signalling cable supplier

Signalling and communications will form a vital element in the Marmaray project, to meet the demands of safety and reliably transporting large numbers of passengers at peak periods. The correct choice of cabling is essential to ensure the safe and effective operation of these systems, so Alstom Transport called in Nexans as the sole supplier for all the specialized signalling and LV cables required – a total of 1,350 km over two years.


The Marmaray contract is an important project that reinforces Nexans’ long-standing partnership agreement with Alstom Transport as a preferred supplier for railways  infrastructure projects worldwide”, said  Eric du Tertre, Business Development Manager for Railway Infrastructures. “The key to win this contract was not only the superior technical capability and scope of our products, but also the high level of service and fast customer response we were able to provide, right from the initial tender stage, with backup and logistical support from our local presence in Turkey (Tuzla factory).
