Following the inauguration of the Jubilee line in the later part of the 20th century, its subsequent extension by means of the Jubilee Line Extension in 1999 warranted stringent measures against structural vibration. London Underground enlisted the assistance of Getzner Werkstoffe GmbH for a suitable solution for its baseplate pads. Having been in constant operation for almost 20 years it was time for a health check; Jonathan Bray, Senior Track Engineer at Amey plus Getzner Werkstoffe’s Stefan Vonbun, Product Manager and Lukas Mayer, Area Sales Manager, provide a brief overview of the results in this article.

More traffic, increasing axle loads and higher speeds are just some of the ongoing technical and economic challenges railway operators and track managers around the world are faced with today. Under Sleeper Pads (USP) have been proven to extend the service life of the track superstructure and help to reduce Life Cycle Costs (LCC).
Geometrical discontinuities along turnouts can lead to strong localised variations of superstructure loads. By using Under Sleeper Pads (USP) with varying stiffness, the bedding conditions can be optimised and as a result the turnout area can be smoothed out. Modern railway tracks need to be able to bear the loads from rail vehicles via the rails, rail seats and sleepers as evenly as possible and distribute such to the track superstructure and subgrade. By distributing these loads sufficiently, stresses on the superstructure elements can be kept as low as possible, helping to minimise maintenance expenses and thus increase the operating life of the track system.
