Gaia, the first EPM TBM certified ''Origine France Garantie'' is ready to start digging the emergency tunnel of the Meudon railway tunnel (3350 m) on Line 977000, Invalides-Versailles Rive Gauche in Paris. “Origine France Garantie'' is the only label that ensures the traceability of products and certifies their French origin.

The EPB TBM (excavation diameter 4.28 m) will dig the 1700 m long emergency tunnel with an internal diameter of 3.5 m. The machine, manufactured at the Bessac plant in St Jory, a suburb of Toulouse, was delivered last September. For further information click fr/125 for the tunnelbuilder archive.
