The purpose of the track stiffness test was to obtain data to assist in validation of the L/V and Lateral Train Stability models as an extension of earlier dynamic tests conducted at the Transportation Test Center. The first series of tests conducted was to obtain instrumented data on Vertical Track Modulus (VTM). The second series of tests were designed to collect data on rail to rail stiffness using various rail loads combined with and without static vertical loads. The third series of tests were conducted to measure lateral track stiffness with and without rail loads on a tangent segment of the track, on both left and right hand curves.
