This article studies the benefits of implementing active steering systems in railway vehicles for the mitigation of rolling contact fatigue (RCF) on rails. Two well-known active steering strategies have been implemented in a simulation model of an existing conventional vehicle, one of them performing with a rather low bandwidth and the other showing a faster response. Simulations with these models on carefully selected scenarios where RCF is predicted with a conventional vehicle are carried out in order to evaluate the potential benefits of using active steering systems for the mitigation of RCF, showing that in some situations, low-bandwidth active steering systems are effective in reducing the propensity to generate RCF, whereas for other running conditions, higher bandwidths are required.
