Tunnel Enlargement Gantry TEP 8400

In Germany and in other European countries, twin-track railway tunnels have been in use since the mid 19th century. Many of these tunnels no longer satisfy the requirements of modern railway operations in terms of cross-section.

High-speed trains and increased safety standards mean the tunnels need to be enlarged. The national German railway company, Deutsche Bahn, developed a concept for the enlargemaent of these tunnels.

The demolition, boring, blasting and support installation work was to take place under the protection of an enclosed gantry through which single-track train operations can continue.

GTA took on the challange and developed and built the TEP (tunnel enlargement gantry) based upon a protective gantry. The first two tunnels to be successfully enlarged using this machine where the J√§hrodter Tunnel and the Mausenm√ľhlentunnel on the Nahe line operated by Deutsche Bahn.
