Expansion of Bern railway station

The main station in Bern is reaching the limits of its capacity. The existing RBS station is being replaced by a new, efficient underground station with four tracks and a new feeder line. The project is being realized under challenging inner-city conditions, in parallel with other concept designs and without interrupting station operations.

The new underground station consists of two station caverns, each 200 meters and 210 meters long, 26 meters wide and 17 meters high. The caverns are located 12 meters below the existing tracks of Bern main station. The 1.5-kilometre-long access route will be constructed with different cross-sections using both underground and cut-and-cover methods. The complexity of the project in the center of Bern is hard to beat: Most of the structures are located in soft rock and some in water-bearing granular soil. The overburden is low, and in some cases the excavation work is taking place directly below high foundation loads, which requires extensive support.

Basler & Hofmann is responsible for the overall management and leadership within the general planning consortium "RBSverbindet".
