Modernisation of the Wengernalp Railway

The Wengernalpbahn has a total track length of 19.2 kilometres with a track gauge of 800 millimetres, with a minimum curve radius of 60 metres. Led by Vossloh Kiepe – today: Kiepe Electric – and in cooperation with the operator, five of the Type BDeh 4/4 locomotives built by SAAS/BBC in 1970 were modernised in the Wengernalpbahn workshops. The central element of the modernisation was the latest drive technology with new AC motors and the corresponding control and converter technology. The on-board electric power supply, which is equipped with new converters by APS, is also a vital component. For more information on the technical specifications click here.
