New Delhi Railway Station — security

I came back to india after 5 years working and leaving abroad.
I came to ajmeri gate side station to pick my sister, aftet getting the ticket for platform i came directly to plateform number 15, i am shocked since i parked my car until plateform number 15 there was no security at all. Wake up guys can be so dangerous even though 15th august is so near. We do not want shocking news in future in terms of anything make the security tight as much as possible.
Hope to see changes soon
