CA 2444896

A system and method for friction management for managing and controlling an application of a friction modifying agent (612) to an area of contact between a railway wheel and a railway rail (710) over which the wheel is traversing to selectively modify the coefficient of friction at the contact area. The system comprises a sensor (610) for detecting a parameter (602) relating to the operation of the railway train. A controller (606) is responsive to the sensor (610) and controls the application of a friction modifying agent (612) to the rail (710) as a function of the parameter (602). An applicator (610) is responsive to the controller (606) and applies the friction modifying agent (612) to the area of contact between the railway wheel and rail (710). The invention also includes a method for railway train friction management for managing and controlling the application of friction modifying agent (612) to an area of contact between railway wheel and railway rail (710) over which the wheel is traversing to selectively modify the coefficient of friction at the contact area. The method comprises sensing a parameter (602) related to the operation of the railway train and applying the friction modifying agent (612) to the area of contact between the railway wheel and rail (710) as a function of the sensed parameter (602).
