The Flendruz railway viaduct carries the Golden-Pass railway line, a tourist-orientated train route in the Swiss Alps between Montreux and Lucerne, across a small valley. It was built at the time of the railway line’s original construction, which was completed in 1905.
After more than a century of service the viaduct needed to be completely renovated, with a focus on enabling it to carry higher loads and reducing noise emissions under railway traffic. These works were carried out in 2011.
mageba supplied a variety of bridge components for this renovation project.
RESTON-POT bearings of type TE (guided sliding), designed to carry loads of 1,460 kN and accommodate longitudinal sliding movements of +/- 25 mm, now support the ends of the main girder beams, while RESTON-FORCE horizontal force bearings resist the transverse forces at these locations while allowing the same longitudinal movements.
At each end of the deck, two RESTON-STU shock transmission units ensure the safe, controlled transmission of unusually large forces between the deck and the abutment.
