Abstract:
1. A computer readable media containing program instructions for controlling application of one or more of a plurality of types of friction modifying agents to an area of contact between a wheel of a railway train and a railway rail over which the train is traversing to selectively modify a coefficient of friction at the area of contact, the computer readable media comprising: a computer program code for recognizing a parameter related to operation of the railway train; a computer program code for selecting at least one type of friction modifying agent from among the plurality of types of friction modifying agents as a function of the sensed parameter; a computer program code for controlling operation of an applicator to apply the selected type of friction modifying agent to the area of contact as a function of the parameter; and a computer code for recognizing a location of the train; wherein the computer program code for controlling operation of the applicator is responsive to the parameter and to the location of the train for controlling the application of the selected type of friction modifying agent; and wherein the computer program code for controlling operation of the applicator is responsive to the location of the train for preventing the application of one or more predetermined types of friction modifying agents along a predetermined section of the rail.
