TRIME project to reduce delays on the third rail
The alliance between Southern and Network Rail is developing a new on-train monitoring system to reduce delays due to third-rail electrical transfer problems.
The third Rail In-Service Monitoring Equipment, or TRIME, project will identify where on the network excessive force is present at the interface between shoe-gear and the third rail.
A modified Class 377 unit will see a set of shoe-gear added to an intermediate bogie and fitted with laser displacement sensors to measure the height of the shoe arm, targeting areas of poor interface performance.
Once processed, the results will be plotted on a map, so maintenance can be targeted more effectively.
Southern’s fleet director, Gerry McFadden said: “TRIME is a marvellous example of just how important the Alliance between us is. By working with Network Rail on this project we aim to reduce the instances of shoe-gear damage and so reduce delays and reduce costs associated with disruption and maintenance. First results have been really positive which has to be great news for our passengers.”
Mark Ruddy, Network Rail’s route managing director for Sussex, said: “We are always looking at ways to make the railway more reliable, efficient and cost-effective. This is an exciting trial which highlights the many areas we can target to achieve this.
“Working closely with Southern, will be able to monitor the conductor rail across Sussex and highlight sections which need to be improved. The results will help deliver a more reliable network which will save the industry money and cause fewer disruptions for passengers.”
