The Rheinbrücke bei Laufen (also called Rheinfallbrücke) is a single-track railway bridge of the Rheinfallbahn , which spans the Rhine in Switzerland between Laufen-Uhwiesen and Neuhausen above the Rhine Falls . The building dates from 1856 and was expanded to include pedestrian walkways on both sides at the end of the 1950s.
history
The Rheinfallbahn was built from 1855 by the Rheinfallbahn-Gesellschaft, which was taken over by the Swiss Northeast Railway (NOB) on November 4, 1856 . The construction of the railway line that connects Winterthur with Schaffhausen included, among other things, the construction of a Rhine bridge between the Neuhausen and Laufen Castle stations at the Rhine Falls, which spans the river about 200 meters above the Rhine Falls. Initially, a 130 meter long iron lattice girder bridge with three openings and brick abutments were intended as structures. However, after a sufficient number of places with stable limestone rock at a shallow depth was found during the work for an auxiliary footbridge along the entire length of the bridge , a re-planning of a brick arched viaduct followed. That meant a cost saving of 90,000 francs. The bridge was built between 1855 and 1856 according to plans by chief engineer Carl Ruland. The construction costs amounted to 220,000 francs. Extensive repairs followed about a hundred years later from December 1957 to March 1959. Among other things, the vaults were reinforced and a gravel trough made of reinforced concrete , cantilevered on both sides for additional pedestrian walkways, was installed. The last time it was repaired was between 2004 and 2007 for 1.2 million francs. A relocation of the Schloss Laufen stop to the bridge was discussed at the end of the 2000s.
construction
The single-track, 177-meter-long railway bridge spans the Rhine at an angle of around 55 degrees at a height of around 10 meters. Since the position of the foundations had to adapt to the rugged river bed, the brick viaduct is not straight in plan and has nine large vaults with mostly unequal clearances between 12 and 18 meters and a small one with 6 meters on the left bank of the Rhine. The distance between the pillar axes is a maximum of 18.6 meters and the vault width is around 4 meters. The upper gravel trough plate made of reinforced concrete, including the cantilever arms with the two 1.4 meter wide walkways, is a total of 7.6 meters wide.
