Experimental approach to estimate the wheel-rail lateral contact force. Decoupling of effects of wheel-rail lateral forces from those of the vertical ones. Analysis of the bending strains in the cross plane of the rail web. Finite element simulations and laboratory tests of the measurement system. Identification of a coefficient by which it is possible estimate the lateral force.
