Formerly named Sarah, Bantan and Armelle, the 3 tunnel boring machines were disassembled at the Eiffage site in Thieux (77). The 28,000 m² site is a veritable Tetris.
Piece by piece, the teams are getting organised to reassemble 3 new tunnel boring machines that will be used to dig the 12.7 km of the future line C of the #Toulouse metro.
This innovative re-use will give the tunnel boring machines a new lease of life and meet the technical specifications for digging the future project.
