The Lise-Enjalbert tunnel boring machine (TBM), which is working on the Toulouse Metro tunnel, is on track to reach its next stop, as French construction company Effage announced.
While the launching location of Lise-Enjalbert for its 4.2km excavation was Ponts-Jumeaux station towards Puits Laporte, it is slated to halt at the future Sept Deniers – Stade Toulousain station.
In order to advanicng the excavation at Toulouse, Eiffage transported its Lise-Enjalbert TBM from its refurbishment workshop in Thieux in November last year.
The TBM’s assembly, including its five trailers, are expected to be completed progressively as it advances, allowing it to reach full operational capacity.
With the aim of accommodating the tunnel’s initial structure, similar to the earlier TBMs, Jeanne-Marvig and Berthe-de-Puybusque, this TBM has been operating in partial mode.
The 4km excavation process of Jeanne Marvig is from Colomiers Gare Shaft to Laporte Shaft, and it intends to reach its first breakthrough by year-end.
Being christened on 31 October at the future La Vache Station, Berthe de Puybusque has commenced its 2.5km journey from La Vache – Le Grand Marché Station to Ponts-Jumeaux Station.
Construction of a new 27km metro line in the Toulouse metropolitan area, with 21 stops, including five interconnections with railway stations, are the contents of the Toulouse Metro Line C project.
Its daily offer of a clean mobility solution, is for more than 200,000 inhabitants.
The new metro line is expected to decarbonise the transport sector by avoiding 28,700 tons of CO2 each year and strengthen the mobility offer for commuters.
