A better understanding of trackbed failure mechanisms through a holistic approach to trackbed investigation

The importance of trackbed investigation in the planning and management of ballasted rail systems has been known for many years. It is however sometimes overlooked and not properly understood leading to abortive track renewal works and increased maintenance liabilities. The failure of the underlying support to the track structure can ultimately result in speed restrictions, delays to service and occasionally to catastrophic failure of the rail system. UK practice has improved on the national rail network in recent years. After decades of renewals undertaken with no coordinated and consistent approach to trackbed investigation across the network, trackbed investigation and design has now been implemented as part of a national strategy. Scott Wilson’s Trackbed Technology team has worked with infrastructure owners in developing this national strategy and acts as preferred supplier for these works across the entire UK rail network. A similar approach has also been developed with London Underground with Scott Wilson working on a framework contract delivering trackbed investigation and design for the current financial control period.
