Renewal of the Railway Power System in Mattsand.
The Matterhorn Gotthard Bahn (MGB) awarded the Rhomberg Sersa Rail Group in Switzerland the contract for the renewal of the overhead contact line in Mattsand (siding station), St. Niklaus in the Canton of Valais in 2023.
In collaboration with Furrer + Frey AG (planning), the overhead line team of RSRG in Switzerland (execution) carried out the complete project for the renewal of the railway power system.
A total of 31 masts, two special A330 gantries, and three additional cantilevers were installed and constructed using special dual-gauge vehicles.
In April 2023, the pre-assembly and equipping of the masts and gantries began. This was followed by the placement of the masts on the foundations, as well as the feeder line installation and grounding of the cable pull.
In October 2023, the demolition of the existing system began, with tracks 1 and 2 being completely dismantled. By November, the new catenary system, including 600 metres of contact wire and catenary wire, was installed and regulated. Before acceptance and successful commissioning, the entire grounding installation was completed.
The extremely intensive work hours took place under extreme weather conditions (snow and rain) at sub-zero temperatures. Despite this, the entire team was fully motivated. All employees pulled together and, with tremendous dedication, did an outstanding job to the satisfaction of all involved.
The overhead line was even released on time so that trains from Visp to Zermatt could run again for the FIS ski race. Unfortunately, the ski race had to be cancelled, but the most important thing was that spectators and skiers were able to travel CO 2-free by train.
The trust that the Matterhorn Gotthard Bahn placed in RSRG Switzerland with this contract, as well as the active support of the Valais colleagues in Gamsen, is highly appreciated.
