Rail connectivity in flood-hit areas in Bihar and West Bengal has been affected too. "However, virtually no accessibility to most of the damaged sites has affected the restoration work. Telecommunication network in the entire section is badly affected also," Mr Sharma said in the statement.
A railway bridge between Maniyan and Kuretha was damaged by floods today morning, disrupting train communication between Katihar in Bihar and Kumedpur in West Bengal.

He said Northeast-bound rail passengers who earlier had to get down at Katihar station in Bihar have taken trains till Malda in West Bengal.
"On date, there are about 120 passengers, who are stranded at Guwahati station and railway administration is taking all necessary steps to extend all possible assistance to these people," the statement said.
