A visit to the tunnel-boring machine for section 1 of Line 14

Five people from the Environment Department at ECT, who were all very interested and impressed, visited the tunnel borer for section 1 of Line 14. They were guided by the teams of Razel-Bec and Eiffage, civil engineering contractors for the first section of 2.2 miles where they are extending Line 14 from Saint-Lazare to the Porte de Clichy. The excavated soil from this machine is handled by ECT.
