DYNAMIC STRUCTURE OF TRACK GEOMETRY

The main objective of this work is to increase the speed of railway. For increasing the speed of railway, the most important part is track geometry. Since the main things are protect the people and comfort of passengers are desired and also avoid the accident. The concerned from dangerous situation like accident is depends on the wheel rail forces in the track plane and comfort of passengers is depends on motions of passengers within the train. The overall dynamic structure of track geometry alignment decides the nature of high speed of railway. The track geometry, track interaction and simulation are three parts of work which deals for increasing the speed of train. In track geometry, the main part is gauges which are used for each high speed rails. The track interaction i.e. track plane acceleration, cant deficiency, cant excess, cant gradient, equilibrium cant needs for developing the high speed rail services in near future.
