In This Paper as it is known that Railways are the second fastest means of transport in the country and therefore it demands great security and safety. The main aim or objective is to prevent all the passengers from any sudden accidents due to rail crack that can leads to derailment. In this particular report the combination of nadal’s theory and the lateral and vertical vibrations of ride comfort have been calculated. On the basis of this information, the frequency of vibrations can be analyzed and efforts can be made to cease any sort of accidents. As it is closely associated with passenger and cargo transportation, it owns high risk in terms of human lives and cost of assets. New technologies and better safety standards are constantly introduced but still accidents do occur. There will always be some risk associated with derailments and collisions but it can be reduced by detailed research of the ischolar_main causes, Indian Railway transport is one of the major modes of transportation, so it must offer high comfort level for the passengers and the staff. However, the comfort that passengers experience is a highly complex and individual phenomenon. In several researches, noise and vibration have been identified as the most important factors for high comfort. The main sources of vibration in a train are track defects, that causes wheel flange climb or rail rollover. The nature of vibration itself is random and covers a wide frequency range. The improvement of passenger comfort while travelling has been the subject of intense interest for many train manufacturers, researchers and companies all over the world. Although new techniques in manufacturing and design ensure better ride quality in railway carriages, it is sometimes impossible to completely eliminate track defects or various ground irregularities.Keywords

The fuzzy means of allocating WDM (wavelength division multiplexing) channels in a hierarchical all-optical network (AON) for the modified token medium access protocol is addressed. The goal is to minimize the average delay of local subnet and global bound traffic, and to maximize the number of nodes that can be supported by the network. This is achieved by allotting a minimum number of spatially-reuse channels to the subnets, which can accommodate a certain maximum number of nodes. Actually the minimum number of nodes that are sought for each subnet in terms of cost. By working out the maximum number of nodes for each subnet and the total subnets that can be supported, the optimum number of global channels and the overall total number of nodes for the entire network, can hence be determined. The packet generation rate and average delay in slot time are used to gauge the performance of the fuzzy channel allocation model. Recent demand for mobile telephone service has been growing rapidly while the electromagnetic spectrum of frequencies allocated for this purpose remains limited. Channel allocation schemes provide a flexible and efficient access to bandwidth in wireless and mobile communication system. In this paper, distributed dynamic channel allocation algorithm is the spatial distribution of channel demand changes with time, the spatial distribution of allocated channels adjusts accordingly. The algorithm guarantees relaxed mutual exclusion and provide necessary condition for information structure. The algorithm is deadlock free, starvation free and prevents co-channel interference.
