An empty gas cylinder was found on the tracks by a goods train loco pilot, who applied emergency brakes and stopped the train near Prempur railway station in Kanpur on Sunday, the second such incident in Uttar Pradesh this month.
Police said the incident occurred at 8:10 am when the train was going to Allahabad from Kanpur.
"It was found that the cylinder was of five-kilogramme capacity and empty. It was removed from the track. The matter is being investigated," the local police said in a statement.
