In another train mishap, seven wagons of a goods train derailed near Sesapani in lower Assam's Kokrajhar district under North-east Frontier Railway on Monday, official sources said.
There was no report of any injury.
The wagons jumped off the tracks due to removal of some portion of a broad gauge track between Kokrajhar and Fakiragram by miscreants with gas cutter, the sources said.
One metre stretch of another railway track between Salekati and Singimari stations was also found to have been cut away but fortunately no mishap took place and it was detected.
Movement of long distance trains got affected following the derailment incident. In neighbouring West Bengal's Malda district, one person was killed and 50 were injured when 11 bogies of Guwahati-Bengaluru Express and a passenger train derailed after a collision at Jamirghata last night.
