The results show that it is more intuitive and effective to study the track dynamic performance by the presented wheel-load-drop FEM model.

The track dynamic characteristic, which is verified by the on-the-spot experiment, is compared between the Low Vibration Track(LVT) and the short sleeper buried ballastless track.

The Vifa XT25TG30-04 1" Dual Concentric Dome Tweeter features a patented dual concentric diaphragm and a unique wave guide center plug which provides an excellent on and off axis response."
