Investigation of baseplate pad life on the London Underground Jubilee Line Extension

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.

The Jubilee line is the newest line in London Underground’s network, originally opening in 1979, and was named after the silver jubilee of Queen Elizabeth II. It took over part of the existing Bakerloo line with a new section being built to Charing Cross. The line was further extended in the 1990s with the so-called Jubilee Line Extension (JLE). This new section opened in 1999.
