Several houses, roads and bridges have also been damaged after breach of embankments led to flooding in many areas, officials said.Meanwhile, the incessant rains have also affected the movement of trains in Assam and the Northeast Frontier Railway suspended train movement on the Lumding-Badarpur Hill section cutting off five states including Tripura, Nagaland, Manipur, Mizoram and Meghalaya from the country's railway map till July 16."At least 15 trains have either been cancelled or terminated due to the suspension of the train movement on the stretch," said Northeast Frontier Railway's Chief Public Relations Officer, P.J. Sharma while adding that movement of trains on the section is likely to resume after July 16."Settlement occurred on tracks between Jatinga Lumpur - New Harangajao station in Lumding - Badarpur hill section on Friday due to incessant rains making it unsuitable for train movement. The repairing work has already started. But heavy rain is continuing in that area making the soil loose. It is expected that the restoration work will be completed by July 16," Sharma said on Saturday.
