NEW DELHI: Railways is looking at ways to sort the water logging problem in the road under bridges (RUBs)/limited height subways (LHS).
Indian Railways has informed the Parliament that the issue is being studied in detail by the Research Design Standards Organisation (RDSO), under the Ministry of Railways.
RDSO has suggested the ministry remedial measures to help solve the problem.
Adequate drainage arrangement is an integral part of the solution. The arrangement needs to be part of planning the new RUBs/Subways, RDSO said.
For the existing structures, feasible remedial measures like water flow diversion to the nearest bridge and ‘nallahs’, provision of the covered shed on approach roads and the hump at the entry to RUBs have been suggested.
To pump out the excess water in a case of waterlogging, a pumping arrangement should be made in identified RUBs/LHS to drain water expeditiously.
As per the suitability of the site and the structure, a provision of cross drains and sealing of joints is also issued.
To prevent waterlogging, steps like clearing of debris and silt removal in the drains are taken at RUBs/LHS before the onset of monsoon season. Monsoon patrolling is also done in the rainy season in identified areas.
Railways have not reported any cases of waterlogging for Road Over Bridges (ROBs)
