Transition zones on railway lines are subjected to particularly high loads. Where a train crosses the transition from ballasted track to slab track, along a section of open track on a bridge, or where the track meets a turnout, track components are subjected to above-average levels of stress. This can cause damage, which increases the maintenance requirements of a route. Getzner's response to this challenge is transition zones optimised with resilient bearings. The bearings even out bedding differences in the subsoil, reducing the stress placed on the components and thereby prolonging their service life. Getzner outlines the solutions in the new brochure entitled “Optimisation of Transition Zones”.
In transition zones – in other words the transition between varying superstructure constructions – wear to the ballast, tension clamp or sleeper breakages and uneven settlement may have expensive consequences. The elastic solutions balance out the loads and protect the components, thus reducing maintenance costs. The vibrations and loads transferred when the train passes over are minimised, which means the components last longer and maintenance and repair costs on the route fall. This measure also has a positive impact on comfort and safety on board the train, and protects buildings in the vicinity.
