Major renovation on the historic Langeac-Langogne line
Our ETF and La Champenoise teams from Public Works and Railways worked for 11 weeks on the Langeac-Langogne line for their client SNCF Réseau. The purpose of this sleeper replacement work was to preserve the legendary Cévenol line, which has connected Clermont-Ferrand to Nîmes for over a century and a half.
Overcoming the challenges of a complex railway environment
This project, which ran from 15 March to 2 June, presented us with a complex environment, marked by restricted access and a multitude of engineering structures, including viaducts and tunnels. However, our expertise enabled us to meet the tight deadlines in just 11 weeks.
The work included replacing 5,200 wooden sleepers, substituting 1,250 metres of rails, renovating a level crossing, 180 metres of localised cleaning, and tamping no less than 25 km in total. In collaboration with Daniel Pastre et Fils, we also successfully drained the track over a distance of 280 metres.
Technical resources mobilised for optimal results
To carry out this large-scale project, we mobilised five rail-road excavators, two locomotives, one tamping machine, and one levelling machine, and deployed up to 50 people to the site during the peak period of activity.
