HIGH-SPEED RAIL LINE BETWEEN WENDLINGEN AND ULM

THE PROJECT AND ITS REQUIREMENT

The new Wendlingen–Ulm line, stretching some 60 kilometres, is a new part of Deutsche Bahn's highspeed rail network. The route runs largely parallel to the A8 motorway and passes through the Swabian Alb.
About half of the route consists of tunnels. The Filstal Bridge, Germany’s third-highest railway bridge, connects the Boßler Tunnel with the Steinbühl Tunnel in this section.

When the train passes at high speed, lateral forces and minimal movements occur in the track support plate of the rigid track. An elastomeric vertical bearing is needed here to absorb the generated forces and restrict minimal movements.

THE SOLUTION

The Calenberg lateral guide bearing is a vertical composite bearing made from weather-resistant stainless steel and a premium-quality, long-lasting rubber compound. The rubber compound is vulcanised with forcefit onto the stainless steel at the factory. The stainless-steel fixings on the rear can be set in concrete within the side wall. This provides long-lasting protection for the joint between the side wall and the track support plate in the track bed.
 

The advantages

• Effective protection of concrete structures against possible mechanical damage
• Absorption of horizontal forces and movements
• Simple installation method, cost-effective solution
