Extension of the East London Line embodies Austrian vibration technology

10. March 2011

As part of linking the East London Line into the London Overground rail network, the existing East London Underground Line was extended in both directions and overhauled at the same time. Previously something of a backwater, following its integration with the London Overground network the East London Line is now a central transport corridor for the entire region. The re-opening of the East London Line took place in 2010.  

Austrian company Getzner Werkstoffe was commissioned by the joint venture general contracting team (Balfour Beatty and Carillion) with the delivery of the elastic components for the entire track superstructure. The East London Line passes through tunnels and also traverses several bridges and viaducts, some of which have tight curve radii. The challenge was to plan a superstructure system for the various permanent way structures which could be implemented along the entire line. Above and beyond this, numerous buildings along the line needed to be protected against vibrations.

In total, Getzner provided 90 tons of PU materials for the combination of light mass-spring systems and individual concrete sleepers on elastic pads. On the customer’s request, Getzner produced the Sylomer® mats with different stiffnesses in two different colours. This production change made a large difference in terms of simplifying transport, storage and installation of the mats.
