Project title

ADHERE: Quantifying the effects of Railhead Treatments on adhesion (COF-DART-01)

  • Project number:

    COF-DART-01
  • Topic:

    Vehicle Track Interaction
  • Status:

    Completed

Project Summary

This project will measure the effects and latency of TGA, ATUST and RHTT/MPV operations on adhesion conditions on the Birmingham Cross City Line. It will compare the effects of different low adhesion mitigation strategies at different sites and climatic conditions.

Project Abstract

Project Briefs are hosted on www.rssb.co.uk
The GB rail industry invests considerable resource on strategies to manage railhead adhesion, for example, carrying out railhead cleaning and lineside vegetation management. Despite these efforts, the direct impact of low adhesion is estimated to cost industry and passengers £345m per annum. A novel monitoring technique developed under RSSB project T1107 'Trial of Sander Configurations and Sand Laying Rates' evaluated the underlying wheel/rail adhesion level. Combining this approach with big data analysis can provide a better understanding of adhesion conditions and the effectiveness of different mitigation strategies, such as train-borne sanders and infrastructure-based traction gel applicators (TGA); to improve their effectiveness by enabling infrastructure managers and operators to better target their application.

This project has measured the effects and latency of TGA, ATUST and RHTT/MPV operations on adhesion conditions on the Birmingham Cross City Line. It will compare the effects of different low adhesion mitigation strategies at different sites and climatic conditions.
