The technical challenges of monitoring ERTMS systems and use of a value engineering approach to increase capacity and reduce costs for the rail sector

摘要

This paper evaluates the role of ERTMS signalling and telecoms systems-wide monitoring and the use of 'value engineering' approach, compared to the more traditional 'fix on failure'. The first part examines the ERTMS components, the errors that can occur and the costs of testing in relation to the product lifecycle. The second part uses 5 case studies to demonstrate how using analytical tools can predict and plan systems maintenance (value engineering) to realise some of the positive cost benefits associated with ERTMS for rail infrastructure operators, vendors and contractors.
