Corrugation removal is associated with significant cost factors for infrastructure owners. The deliberate addition of a water based friction modifier into the tribological system between wheel and rail provides the necessary means to mitigate or even suppress the mechanisms associated with corrugation formation (wear, plastic deformation) and growth. This paper discusses these mechanisms, effects and improvement factors with respect to corrugation suppression at various passenger rail systems achieved by effective application of the water based friction modifier KELTRACK®. Besides the technical background the economic benefits of this sustainable approach will also be analysed and discussed. © 2016 Taylor & Francis Group, London. Source


Patent
L.B. Foster Rail Technologies Inc. | Date: 2011-05-19

A wayside friction management system, and method for monitoring and controlling a wayside friction management system is described. The system comprises one or more wayside device for mounting with a track of a rail system. The wayside device comprises a delivery system connected to a reservoir comprising a friction control media, the delivery system for applying the friction control media from the reservoir to one or both rails of a track. The wayside device further comprises one ore more data collection module located at or adjacent to the delivery system. The data collection module for collecting and transmitting data to a remote performance unit. The data may comprise performance information, track status information, information of an environment of the track, information of a train passing over the track, status of the one or more wayside device, or a combination thereof. The wayside device may comprise a power source operatively connected to one or more components of the wayside device.

This paper describes two methods for assessing friction modifier performance carried out on two different testing scales. Study A used wear data from a full scale rig test at Voestalpine Schienen GmbH [1] and compared it with wear data from twin disc tests using the SUROS machine at The University of Sheffield. Study B compared 'retentivity' data from a full scale rig at The University of Sheffield and the SUROS tests. Study A concluded a good correlation between the two scales although assumptions made in the full scale contact calculation introduce a large spread into the results. There was a greater correlation between the two data sets at more severe contact conditions. Study B showed a different baseline coefficient of traction between the two scales and a longer test length is required to fully evaluate the 'retention' of the friction modifier on the full scale rig. © Civil-Comp Press, 2016.
