France – Reopening of the Echoppes Triangle
With the reopening of the Triangle des Echoppes junction, passengers from the outskirts of Bordeaux have had their journey times cut from 1 hour to 33 minutes between Pessac and Macau.
The Echoppes Triangle, a 1.5 km single track junction closed in 1951, has been entirely rebuilt and electrified, and given a 50-metre span railway bridge, named ‘Julien Ducourt’, to take it over a road junction in a built-up area.
This new section of track, which no longer goes through Bordeaux-Saint-Jean station, cuts journey times between the orbital railway line in Macau and Pessac station to 33 minutes instead of an hour. On weekdays, nine outward and return services are run each day by TER.
The reopening of this railway line is part of a drive to improve multimodal transport services in the western part of Bordeaux, along with the extension of Tramline C to Banquefort. The Pessac-Macau line has 8 stations connecting with Tramlines A and B.
SYSTRA is responsible for the general project management, design and construction of all aspects except signalling, which is managed by SNCF Réseau.
In particular, its responsibilities include the following:
- Preliminary project designs
- Detailed designs
- Consultation documents
- Works contracts assistance
- Performance studies certificates
- Works contract delivery
- Assistance during acceptance operations
- Testing and commissioning
The upgrading work carried out at the junction required the laying of track and track equipment, installation of a 1500V catenary, and modernisation of the signalling and telecommunication systems. To make it easier for passengers to access the trains, platform 2 at Pessac station was also extended.
