Carrier separation with brake elements on the post head saves on two anchoring points at ground level. Carrier separation on the post head also enhances safety, as it is installed at height and thus protected from rockfall.

Situação inicial

Within the concept of "The Rehabilitation of the Karwendel and Ausserfernbahn – A Railway for Mobility", the line was further protected from natural disasters in 2015.

Since its commissioning in 1912/13 as the first completely electrical railway in the former Monarchy of Austria–Hungary, the line has now developed into a popular railway. Today, the route is considered a premier historical landmark, with early Alpine railways, numerous railway buildings, bridge structures, and a natural stone tunnel having protected status.

Due to damage from storms and harsh winters, the section between the tunnel portal, above the site of the Burgenwelt Ehrenberg castle and mountain road B179, was likely to be struck by rockfall.

As far as tourism and infrastructure are concerned, a secure railway connection between Ausserfern-Reutte and Innsbruck is of huge importance.

Descrição

Four RXE-500 rockfall barriers were installed to protect the railway line, the B179 road running directly below, part of the area of the Burgenwelt Ehrenberg tourist site, and the highline179 pedestrian bridge against falling rocks, blocks, and trees.

A double-walled enclosure of just 13 meters connected to the rock secures the tunnel portal. Three rows of RXE-500 run parallel to the track, with a total length of 207 meters. All barriers were designed with an overall height of 3.5 meters. A series of cables, with a length of 100 meters, has a carrier separation with intermediate suspension after 50 meters. This adheres to the requirements set out by the ONR (Austrian Standards).

Due to its exposed position, the task of carrying all construction site equipment and the installation of the RXE barrier had to be undertaken by helicopter.
