Railways is planning to seal stations just like airports and passengers would have to arrive 15-20 minutes before scheduled departure of trains to complete the process of security checks.

The security plan — with high-end technology — has already been put in motion at Allahabad, in anticipation of the Kumbh Mela, which begins this month, and at Hoobly railway station in Karnataka with a blueprint for 202 more stations ready for implementation, Railway Protection Force Director General Arun Kumar said.
