Patna: Former Railway Minister and RJD chief Lalu Prasad today blamed railway officials for the mishap involving the Dibrugarh-bound Rajdhani Express that left four passengers dead.

"I have been the Railway Minister and I know that a pilot engine is run 30 minutes ahead of Rajdhani Express trains.
This is done to check whether the line is clear and tracks are safe. It seems this was not done in this case and the accident happened," Prasad told PTI over telephone.
