A major accident was averted after a goods train ran on the tracks driverless for about 70 kilometres in Punjab today, triggering a scare. Officials said the driver forgot to pull the hand break before getting off the train - that was on a halt at the Pathankot station - because of which it started moving on a sloppy track. The goods train - carrying stones - crossed about five stations before it was stopped in Uchi Bassi. "The train was stopped after a Railway official placed wood blocks on the tracks to stop the train," officials said.
