The problem we are addressing
The problem stems from the fact that we are not simply dealing with crispy, wafer-thin leaves on the track.
Leaves fall on and around the track and as the train passes the aerodynamic effect will deposit more leaves onto the track.
When the train passes over the leaves, the wheels compress them into a paste, with a force of around one gigapascal (30 tonnes a square inch), between the wheel and track.
The leaves are transformed into a black Teflon-like surface (called a 3rd layer contaminant), that’s bonded to the track surface.
This super slippery layer reduces grip, meaning trains need to accelerate and brake gently to avoid slipping.
