GB-London: T1222 ADHERE Understanding how railhead and wheelset contamination affects track circuit performance

Descriptions

Building upon previous research, this project will provide the GB rail industry with: •A greater understanding of the impact of railhead and wheelset contamination on different types of track circuit reliability; and the effects on risk and train service performance •An improved insight into the management and interlocking performance of track circuits •An improved understanding of the impact of operational planning and mitigations on reducing WSTCFs The project shall source and analyse operational, rolling stock and infrastructure data for 4 - 6 case study lines. Experimental testing shall also be undertaken to assess the influence of wheelset contamination on track circuit performance.
