The TEVO/REVO, from Hauts-de-France to the heart of Paris
In March and April 2023, Suite Rapide Zone Dense (SRZD) renewed 15 km of ballasted track (RVB) between Maurois and Busigny (59) in the Hauts-de-France region. The two TEVO and REVO work trains operated outside the Paris region for the first time./strong>
Ce transfert momentané d’activité représente le dThe temporary transfer of activity involves the relocation and installation of 300 people, a rear base, and a wide range of equipment such as work trains, dozens of maintenance workshops, equipment storage containers, and specialised construction machinery such as rail-road excavators, tamping machines, and levelling machines.
This freight route is in operation 24 hours a day, 7 days a week, and is considered the main axis. To meet these requirements, our Major Railway Projects teams had to put in place a flawless logistical and operational organisation, as well as maximise the use of resources. On certain nights, mechanised renewal work and off-sequence work took place simultaneously a few kilometres apart.
Our adventures continue towards Paris!
The PSO3 construction site between Ivry-sur-Seine and Athis-Mons is located just 2 km from Austerlitz station. This densely populated area is characterised by a heavily used and worn railway network, with contiguous tracks and multiple intervention areas that do not always follow each other.
The major challenge for SNCF Réseau is to ensure that trains continue to run during the works. Our teams seek to ensure not only maximum efficiency every night, but above all the safety of the tracks and the timely restoration of the line. Every morning, thousands of users depend on the availability of transport.
Key figures for the 2023 campaign:
To date, the Suite Rapide Zone Dense campaign has achieved:
- 36,139 linear metres renewed with TEVO
- 1,394 linear metres renewed with PUSCAL
- 44% of the campaign was completed in June 2023
- i.e. 3 out of 6 sites
About:
Industrialised track renewal in dense areas is a multi-year market. ETF uses factory trains called ‘Rapid Suites’ (TEVE/REVO and PUSCAL) for industrialised track renewal in dense areas. These trains enable mechanised renewal five times faster than traditional methods by replacing all track components (ballast, sleepers, rails and rail fastening systems).
