Bhubaneswar: The East Coast Railway (ECoR) authorities have adopted micro-tunneling system to clear the logged water from the Bhubaneswar railway station yard which was earlier affecting not only the signaling system but also train services as a whole in the Howrah-Chennai main line.
Since long time, the drainage system and clearance of logged water from the Railway Station yard and surrounding areas during heavy rains was a major problem. The municipal drain connecting to station areas was inadequate to discharge heavy flooded rain of the area. The huge quantity of rain water from Ashok Nagar area and station area overflows and comes to south end and also north end of station yard.
The flooding of yard by heavy rains was making the points nonfunctional and leading to signal failure and ultimately resulting in disruption of train traffic. The passengers were also facing a lot of inconveniences due to disruption of traffic. Even passengers had to walk up to the flooded platforms sometimes thereby soaking their footwear, clothes and luggage items, etc.
The rebuilding of the bridge was planned but it could not be executed due to difficulties in execution and also for huge demand of traffic block which is very difficult as huge numbers of trains are originating from Bhubaneswar station itself and also due to heavy traffic on Howrah-Chennai main line. Therefore, it became essential to explore some innovative technology in which the detention of traffic shall be marginal.
The drainage problem of the yard is expected to be eliminated after implementation of the tunneling method and passengers will not face any problems during heavy precipitation in future.
