Renovation and widening of the Petersberg Tunnel

Neef, Germany

The Petersberg Tunnel in Germany no longer complied with modern re­quirements. This is why Deutsche Bundesbahn commis­sioned us with its re­novation. Both the de­molition of the old tunnel and the con­struc­tion of the new tunnel needed to be carried out while the tunnel was still in service, i. e. under live over­head contact line systems. Marti sig­nific­antly ex­panded the scope of tunnel re­hab­ilita­tion with its specially de­veloped tunnel-in-tunnel method.
