Abstract

The need for better asset condition data is driving change within the UK rail industry in terms of embracing new technology. With good quantitative data, we can better analyse asset condition and deterioration rates which will improve decision making on maintenance interventions and track renewals specifications. This is particularly true for track bed investigations. The Pandoscope is a simple and quick non-intrusive test that produces quantitative data to make site specific decisions. It can replace the time-consuming trial holes and the automatic ballast sampler, generally used in the UK. A case study is described in this paper to highlight the difference in approaches between the UK and France. The outputs of both methods are compared and the benefits of using the Pandoscope are demonstrated by a reduced track bed specification. Finally, proposals are made with the quantitative outputs with limits for potential changes to Network Rail standards.
