the increase in traffic, the station at Zermatt was completely rebuilt between 1982 and 1989. All of the platform tracks were given an avalanche proof canopy, and the west side of the track layout has since been bordered by a massive 300 metre long avalanche wall. The Zermatt station building, which had been in place ever since the opening of the line, was demolished and replaced by a larger new building. A second major construction project followed between 1983 and 1984, with the erection of the Glisergrund Depot near Brig. This depot partially replaced the space-constrained depot facility at Visp station. By 1998, the Furka Oberalp Bahn had extended the Glisergrund site, by adding a further workshop hall. The complete depot site now occupies an area of around . The Randa landslide The biggest disaster in the history of the BVZ occurred in its jubilee year of 1991. On 18 April at 6.45 am, approximately 15 million cubic metres of rock broke away from the Wartfluh northwest of Randa and buried the Vispa and parts of the hamlet Lerc, along with 100 metres of railway track. No people were injured, as the hamlet Lerch was uninhabited and at the time of the landslide there was no train in the affected section of track. However, a goods train heading for Zermatt was left standing a few hundred metres north of the incident site, after its traction failed due to damage to the overhead line and the resulting short circuit. Passenger and goods traffic was temporarily moved to the road, which was left undamaged. Between Herbriggen and Randa, omnibuses operated bustitution services, and between Randa and Zermatt the trains ran in a shuttle service. As from 22 April, it was again possible to operate through goods trains, for which a diesel locomotive of type HGm 4/4 was hired from the Furka Oberalp Bahn. Passenger traffic initially remained suspended, as further landslides could not be ruled out. On 9 May, large rocks fell into the valley once again, burying the railway tracks for 250 metres and also making the road along the valley impassable. Moreover, the alluvial fan dammed up the Vispa, causing the lower part of the hamlet slowly to become flooded. After heavy rains on 18 Juny 1991, the station was similarly left under water. Planning immediately began for a new route for rail and road that would by pass the
