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. The RER A line was reopened for passengers on 21 August, in line with the schedule announced by the RATP.
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 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.
