Alstom finalises its intervention on signalling and speed control equipment for Line A of the RER

Alstom carried out, between 23 July and 21 August 2016, the dismantling and reassembly of signalling and speed control equipment necessary for the renewal of ballasted track on Line A of the Paris RER.

During the four-week operation, the 40 members of the Alstom teams made their expertise available to the client, RATP, 7 days a week. The RER A line was reopened for passengers on 21 August, in line with the schedule announced by the RATP.

The complex operation took into account working conditions in tunnels and difficult access, leading Alstom's teams to intervene over several kilometres of line, on different sites and to very strict deadlines, to enable traffic to resume on the scheduled date. The Alstom teams effectively removed over 150 items of signalling equipment, namely beacons, track circuits and track speed control equipment, so that the teams of Colas Rail could intervene in their turn.

The public works company then worked 24 hours a day to renew the ballasted track. Once the new ballasted track had been installed, the Alstom teams reinstalled the signalling equipment and carried out performance tests to avoid any problems linked to the opening of the line.

"This operation confirms Alstom's knowhow in managing signalling works and demonstrates our expertise and flexibility in complex urban rail projects, at the service of our clients, and in this case the RATP," said Benoit Pellerin, Managing Director Infrastructure France.
