Weigh-in-motion (WIM) systems are designed for the dynamic weighing of railway vehicles by using different measurement stations placed along the track.

In this paper the authors propose an innovative algorithm for high speed dynamical WIM applications with the aim of estimating the axle or wheel loads of a generic train composition starting from indirect track measurements. The adopted approach is quite general and it can be customized for several track measurements (rail shear, rail bending, vertical forces on the sleepers etc.) as well as a combination of them.

The algorithm is able to manage both experimental data and simulated ones; the first one are aimed to test the algorithm (in terms of accuracy and robustness) under any operating conditions especially when experimental data are not available.

A wide simulation campaign has been performed to verify the algorithm accuracy, obtaining good results. Future developments of the work, described in this paper, will consider experimental data coming from some dedicated experimental programmes performed by Ansaldo STS and ECM SpA, the industrial partners of this research project.
