The reconstruction of old railway tunnels, which are rarely equipped to handle the requirements of modern railways, has become established as a a separate field of expertise. The Bahntechnik Group has access to a modular range of plant and machinery specifically adapted for different types of work relating to rail tunnels. Alongside tunnel improvement methods, the removal and disposal of the original sites and the creation of new sections (including fixed tracks and mass-spring systems) is also systematically managed.

Further information on the redevelopment of railway tunnels can be obtained from the homepage of Rhomberg Bahntechnik.
