Reconstruction and expansion of the Bönigen workshop

BLS is expanding its Bönigen workshop until 2027. The workshop is being comprehensively renovated and modernised.

BLS will concentrate all major repair and upgrade work at its Bönigen workshop by no later than 2027. This consolidation will allow BLS to conduct all such work centrally, efficiently and in an operationally logical manner. To this end, the workshop is being reconstructed and expanded over the coming years. BLS thereby continues to be a major employer in the Bernese Oberland.

From 2019 to 2027, BLS is constructing several new buildings in Bönigen. A new motor-bogie and wheelset hall as well as a new technology building will be constructed on the existing site. These will be joined by a logistics building and a hall for 105-metre-long trains. The transfer table on which the vehicles are moved between these two buildings is being overhauled. The offices, changing rooms and reception are being modernised in line with today’s requirements.
