Train Detection

Failure Investigation and Rectification

Synergy Rail was commissioned as world-class experts in Train Detection to investigate the root causes of the high failure rate of the EBI200 Track Circuits installed by the SUP Immunisation Project on the Wimbledon Branch in December 2011. The LU Maintenance Faulting Teams were unable to identify the root cause of these failures, prompting an investigation demanded by the TfL COO. Synergy Rail was tasked with proposing short- and long-term mitigations to improve system resilience.

Client: LU (TfL)

Date: 2014 – 2015

Activities & Deliverables

Synergy Rail provided specialist support to:

  • Identify the root failure causes using proven root cause techniques
  • Carry out an analytical assessment of the EBI 200 track circuit system to aid understanding of the conditions causing the failure of the system and establish the integrity of the system
  • Characterize the integrity of the EBI 200 track circuit system through surge testing of the unit in an accredited EMC test house to establish susceptibility of the unit
  • Develop a model of the system (equivalent circuit or otherwise) to assist in identifying coupling mechanisms
  • Conduct testing to identify failure conditions and causes of failures
  • Identify recommendations for implementation
