Rail companies to experiment with lasers against leaves

By

ProRail is planning to use lasers to burn off the leafy mulch that coats rails in the autumn, Z24 reports.

The experiment is a collaboration between ProRail (network), Dutch Rail (operator) and Delft University of Technology. In another test, suggested by a train driver and also held this autumn, ProRail will wet rails to prevent leaves from sticking to them.

A similar trial with lasers was done in 2006 in the UK. At the time, ProRail felt the technology was not good enough. Industrial Laser Solutions has an interesting article about the technology.

In the autumn falling leaves form a mulch that cause train wheels to slip and slide. As a result, both braking and accelerating go slower, causing delays in the service.
