Level crossing segments made of in-situ concrete for slab track systems.
For safety reasons, it must be possible to drive road vehicles in railway tunnels – often a challenge when installing tracks.
So our level crossing segments, developed in-house, for slab track systems are now in use for the first time in the tunnels on the new Wendlingen-Ulm line.
As part of the “Eisenbahntechnik Schwäbische Alb” (ABSA) consortium, Rhomberg Bahntechnik GmbH is jointly responsible for the new section of the Wendlingen-Ulm line. All the tunnels along this line which are more than one kilometre long are to have level crossing segments made of in-situ concrete that are negotiable by emergency service vehicles. The level crossing segments will be installed from the tunnel portals to the rescue stations as well as on the Filstal bridge. The system was originally designed by Ed. Züblin AG, and is now being further developed in cooperation with Rhomberg Bahntechnik to meet the requirements of the new line. For example, a clever solution was found to ensure that the gap between the level crossing segments and the rail is narrow enough for emergency vehicle tyres, but still wide enough to ensure that the rail fastening and sleeper head can be inspected. The formwork frames of edge elements were designed to be width-adjustable to compensate for track bench tolerances. And: An easily adjustable coupling was developed to safely prevent any movement of elements due to inclined tunnel tubes.
All in all, railway operators benefit from the ease of installation, the wide range of adaptation options for various installations, the robust and maintenance-free design and, ultimately, from a high level of cost-effectiveness.
