This paper makes a survey on the current development, underlying issues, and the future prospects associated with China railway signalling monitoring technologies. To overcome the problems involved such as interconnection, data sharing and intelligent analysis, an integrated scheme of the intelligent monitoring and maintenance system for railway signalling systems is further presented. In this scheme,...
Track circuits form a critical part of the UK rail signalling infrastructure. Condition monitoring of track circuits may improve the availability of track circuits, hence improving service levels. Audio frequency track circuit condition monitoring is a relatively new concept and little work has been done on the subject. This paper describes the instrumentation of a length of active track to observe...
During re-signalling of London Underground's Northern Line innovative methods were developed to provide a step change reduction in the number of track closures and improvement in reliability monitoring and performance. The techniques and technologies developed are also applicable to in-service reliability improvement programmes.
