the balancing reservoir of a hydroelectric power station at Herbriggen. In close proximity is the crossing station Mattsand, which was built in 1956 for the construction of the power station, and has been used since 1964 for train crossings. The nearby Herbriggen station has, apart from two platform tracks, a connecting track for a substation associated with the power station. The original station building no longer exists; it was replaced in 1966 by a new structure. The next section of line to Randa is shaped primarily by the landslide of 1991, which buried 250 metres of the then existing line and necessitated extensive new line construction. Behind Herbriggen, the line initially follows the course of the Vispa in the middle of the valley. Shortly before the alluvial fan, however, the line curves sharply to the left and runs together with the valley road at the extreme edge of the valley floor, in order to avoid the area of land threatened by possible further landslides. South of the alluvial fan, the formation descends at a gradient of 120% and returns to the original route along the Vispa. The entire bypass section is equipped with racks. Since 1991, this has also been the only location where a rack is required for trains heading towards Zermatt. Randa–Zermatt At Randa, the railway line runs along the western edge of the town. The station has two platform tracks and a goods track. The station building dates from the line's opening in 1891, and to this day has been rebuilt only slightly. South of Randa, the line passes the hamlet Wildi, where from 1960 to 1966 there was a loading track for the construction of the Grande Dixence power station. The line then meets up with the Mattervispa once again, and runs further on the route to Täsch directly parallel with the river along the valley floor. The station at Täsch has been particularly important since the 1970s, as the end point of the part of the valley road available for use by motor vehicles. Originally a simple two track crossing station, the Täsch station site was expanded in 1975 by the addition of a separate platform track for shuttle trains to Zermatt. At the same time, the 1891 station building received a modern extension housing a ticket office, while the fields surrounding the station were transformed into parking spaces. Beginning in 2005, the whole Täsch
