From supply to commissioning – the RSRG provides everything from a single source
The Koralmbahn with its centrepiece, the Koralmtunnel, is one of the most important infrastructure projects in Europe.
This is also the opinion of the Austrian Federal Railways (ÖBB), which is ensuring that passengers will be able to travel faster, more comfortably and right through the mountain massif from Graz to Klagenfurt in the future. And for the Rhomberg Sersa Rail Group, this significant section of the new southern line in Austria is a prime example of what a broad-based rail technology service provider can achieve for its rail customers: Four RSRG companies are working there: Rhomberg Bahntechnik, RK safetec, Universale Bau and Rhomberg Fahrleitungsbau from the BBW Group.
“Of course, we are working closely with many competent and high-quality partners on the Koralmtunnel/Koralmbahn project. But our range of services for this prestigious project gives a very good overview of what we are capable of achieving”, says Thomas Bachhofner, CEO of the Rhomberg Sersa Rail Group, proud of his team's achievements. Especially since the customer has been absolutely delighted with the performance so far: Rhomberg Bahntechnik has already been awarded construction sections. “We have already taken on tasks such as the deli-very of the overhead line support points or the manufacture and operation of the construction temporary structures in the first phase. The second phase will directly benefit the installation of the railway equipment, i.e. all cable construction services, telecommunications, energy and safety technology, mechanical equipment and construction services such as breakthroughs and metal construction,” explains Robert Kumpusch, Managing Director of Rhomberg Bahntechnik.
As a result, Rhomberg Bahntechnik is now responsible for the construction and commissioning of the slab track in a joint venture, as well as all other construction measures through to the commissioning of the 33-kilometre-long Koralmtunnel. Thanks to its ZOKA system, RK safetec ensures secure access, localisation, communication and alarming in the construction area and thus decisively for the temporary construction infrastructure. The challenges outlined, apart from the dimensions of the project, include the handling of the remote BE area and the integration of the existing infrastructure from the shell construction.
Together with a joint venture partner, Universale is provi-
ding support with the construction of ballast and loading tracks, wash tracks, switches around the stations in Wettmannstätten and St. Paul im Lavanttal, as well as the use of a gantry crane to lay the sleepers and concrete slabs. The future dismantling of the loading tracks is also the responsibility of the commercial track construction specialist in the Rhomberg Sersa Rail Group.
Rhomberg Fahrleitungsbau was awarded contracts by the developer for the installation of the overhead line from the Jauntal bridge up to and including the Lavanttal train station, the equipping of the approximately six-kilometre-long Granitzaltunnel with an overhead conductor rail and support for the installation of a traction current supply system for the Koralmbahn. The Klagenfurt switching stations and the Grafenstein and Lavanttal substations made notable contributions here.
