Around 4,000 masts and 250 kilometres of overhead line are being laid. The construction work involves 35 road overpasses as well as 38 level crossings; three road bridges and two pedestrian and bicycle path connections are being newly built. After the completion of the construction work, rail passengers will be able to travel from Lake Constance to Stuttgart without changing trains and the speed will be increased step by step to 160 km/hour.
In addition, the single-track railway around Lake Constance, which will mainly run along the northern shore of Lake Constance, will connect the traffic to the international passenger and freight traffic on the Austrian and Swiss sides. The electrification of the Friedrichshafen – Lindau line as well as the modernization of the Lindau rail junction, which has been underway since 2016, complement the Southern Railway project. To this end, the Lindau-Reutin station on the mainland will be expanded into a traffic hub for regional and long-distance traffic in order to avoid the time-consuming locomotive changes at the Lindau terminus station on the island of Lake Constance. Lindau’s main station is also being renovated with an electronic interlocking system replacing six old signal boxes.
