Automated Railway Maintenance System in Context of Bangladesh

Bangladesh railway system mostly relies on manual maintenance system. At present, a trolley car is used in which people go in person to examine the railway system depending only on their vision. Mostly, these checking include detection of rail line cracks and obstacles, existence of sleepers in the proper places etc. However, the inadequacy of this kind of maintenance system is one of the vital reasons of railway accidents. The current procedure is also time consuming and costly. Besides, one of the leading causes of railway accidents is attributed to human error which can be reduced through automation. This paper attempts to improve the railway maintenance system and convert this into an automated one. Here, we are introducing a sensor based arrangement which reveals problems like surface crack, unaligned rail lines, obstacles on the railway and also inspects the correct position, presence and absence of the sleepers with the convenience of sending the location and distance to the proper authority.
