    Many structural elements are exposed to load conditions that are difficult to model during the design stage, such as environmental uncertainties, random impacts and overloading amongst others, thus, increasing un programmed maintenance and reducing confidence in the reliability of the structure in question -- One way to deal with this problem is to monitor the structural condition of the element -- This approach requires supervising several signals coming from critical locations and then, performing an accurate condition estimation of the element based on the data collected -- Herein, this paper implements a method to diagnosis and evaluate the reliability of the bolster beam structure of the railway-vehicle during a fatigue test -- The results show that multidimensional monitoring not only provides an accurate diagnosis of the element, but also that this technique allows to estimate reliability correctly
