I wouldn't be surprised if there was breach of information. & i believe an article similar to this was covered couple of days ago.
A breach doesn't mean that Indian Railways purposely let it happen. They sure might have been slack. Look at human history & there has been a breach even in the most secure organizations in the world. Its all about the will to make it happen.
We sure need to get together & make a stronger will to not let it happen again.
