Light as bright as day to make the work easier

Illumination of the cavern in the Lötschberg base tunnel with the StreamLED 2

Initial situation

The Lötschberg base tunnel had to be temporarily closed because an unexpected ingress of water washed sand into the eastern tube. A cavern is being built outside the tunnel tube to prevent further ingress of water and sand into the area of the railway. The StreamLED 2 was delivered and installed in a very short time, so that the cavern is now adequately illuminated.
