Managing the Top Of Rail (TOR) wheel/rail coefficient of friction, using friction modifiers (FM), has consistently demonstrated significant benefits to the heavy haul industry including fuel/energy savings, wheel & rail wear reduction, and reduced state of stress of the track infrastructure. Traditionally, the preferred method of FM application has been trackside systems. However, in some situations, it is desirable that friction modifiers are applied from on-board a train set due to several different factors. Recently, Shuohaung Railroad have installed three (3) prototype on-board TOR dispensing systems on their SS4B locomotives and have been successfully operating them for the last three years. Field testing, conducted by the Chinese Academy of Rail Sciences, have demonstrated energy savings of approximately 5 %, lateral force reductions of 10-20 %, and following train benefits for non-TOR equipped train sets. Simple cost benefit analysis modelling is shown to favour on-board FM application over trackside FM application.
