The effect of soft primary lateral springs in reducing dynamic lateral force was investigated. The use of lateral dampers to maintain critical speed was also investigated through dynamic simulation. Dynamic lateral force occurs when railway vehicles are passing over irregularities in the rails. The simulation results showed that using soft primary lateral springs is effective for reducing dynamic lateral force caused by a short wavelength (e.g. 3 m) lateral irregularity. However, using softer primary lateral springs can slightly reduce the critical speed of the vehicles. The simulation results also showed that using the lateral primary damper can prevent this reduction in critical speed. The effect of reducing lateral dynamic force by using both softer lateral primary springs and lateral primary dampers is confirmed by the simulation results.
