The benefits of friction management are already known through numerous studies. Rail wear , wheel wear and noise reduction are variables that were extensively showed as successful results of FM application. However, the benefits of increased operational safety when using friction management are still poorly proven. Physically, the reduction of forces acting on the wheel rail contact leads to an increase in railway safety, however, the number of accidents and railway occurrences is difficult to measure, due to the lack of information, amount of variables involved or the very low history of rail accidents of rail users.

Due to the large focus on safety adopted, the friction management in Rumo's rail network aimed to reduce the number of rail accidents in areas identified as critical; areas with a considerable number of rail accidents. Based on this project, Rumo’s engineering team was able to measure in numbers the reduction of accidents caused by managing friction efficiently. Variables that could affect the numbers such as railway conditions, rolling stock and train operation were isolated.

This study will present the strong relationship between the use of friction management to reduce railroad accidents and increase operational safety, showing in real numbers the methodology and the percentage of railroads accidents
