Leaves on the Line Could Become a Problem of the Past

Experts from Loughborough University, the University of Sheffield and engineering firm Perpetuum are developing an on-board system that can identify low adhesion hazards such as leaves on the line.

Currently these types of hazards are hard to be monitored or controlled, and cost the UK rail industry an average of 350 million GBP (419.05m euros | 473.73m USD) each year.

The ‘LAD system’ would complement existing methods of understanding the locations of low adhesion, such as the triggering of wheel slip and wheel slide protection systemsThe ‘LAD system’ would complement existing methods of understanding the locations of low adhesion, such as the triggering of wheel slip and wheel slide protection systems

The new partners aim to develop a system that’s capable of detecting low-adhesion hot spots in real-time and creating a live map of the UK’s network highlighting where potential hazards could be found.

This will enable network operators to react more quickly to potential risks ensuring rail safety and eliminating delays.

The detection system will use established sensing methods to pick up small changes in how the wheels of a carriage respond to different track conditions.

This data will then be processed using newly developed algorithms and if required, a warning can be sent to the driver or network operator.
