This paper presents a methodology for predicting vibrations produced by underground railways through 2D FEM numerical models formulated in the time domain. The numerical approach is based on the application of train loads as dynamic displacements on the rail pad and the application of load correction coefficients in 2D numerical models. This load reduction coefficient is calculated by comparing 2D and 3D static numerical models, assuming that vertical displacements are equal in both cases. This
