Renovation of the platforms at the heart of Paris’s Gare de Lyon station

Since its construction in 1849, Paris’s Gare de Lyon station has continued to evolve to accommodate the increasing number of passengers passing through its platforms. Today, it is France’s busiest station, with 350,000 passengers per day and trains arriving or departing every two minutes.

Compliance for passenger service

To facilitate access to trains for all passengers, SNCF Gares & Connexion has undertaken extensive accessibility work, initially in Hall 1 and later in Hall 2. These projects are part of the National Accessibility Master Plan, which will ultimately facilitate access to the 160 stops on the national rail network.

To carry out the work in Hall 1, SNCF called on a consortium comprising entirely of VINCI Group companies, namely ETF (civil engineering, mechanised works and catenary systems), Sogea Île-de-France (lead contractor), SDEL, Feroway and Jean Lefebvre.

Renovation of 7×400 metres of platform

From October 2021 to June 2022, the consortium will carry out raising and levelling work on the seven 400-metre-long platforms that make up Hall 1. For each platform, the operational teams will work for four weeks: three weeks of night work, three weekends of three-shift work and one week of finishing work.

This work involves removing the existing asphalt, sawing the platform horizontally, installing a vigilance alert slab (DEV), carrying out the electrical installations necessary for lighting and platform signage, and then laying a new asphalt surface.

In total, nearly 70 operational staff are involved in these operations, working day and night, and depending on the peak of activity, between the arrival and departure of thousands of passengers. This extremely dense area requires excellent logistics, adherence to deadlines and increased vigilance in terms of site safety.

Details per platform:

• 400 DEV units to be installed
• 150 m3 of concrete to be laid
• 240 tonnes of asphalt
• 3 rail-road excavators
• 1 work train
