Under this latest contract, the Colas Rail / Alstom consortium will supply and lay 10 kilometres of track, the rigid overhead catenary system and the linear equipment between Le Bourget Aéroport and Parc des Expositions. This will involve work within in a tunnel, in embankments and on a viaduct.

The first works will start by mid-2024 and will involve up to 200 employees from Alstom and Colas Rail.

This contract follows the two companies’ previous collaboration on projects such as the Grand Paris Express line 15 South-East section.
