Union Minister Adhir Ranjan Chowdhury said it was not possible for railways to provide fool-proof security to its vast infrastructure and asked states to give "more attention" to it, as a twin blast in a train in Chennai claimed a woman's life.
Chowdhury said railways tracks were spread over 64,000 kilometres in the country.
"Such a vast railway tracks pass through thousands of villages and jungles. So how can railways ensure security of each and every place? It is not possible for railways to give full proof security to it.
"So the state governments should give more attention to it. They have Government Railway Police (GRP) for this." said Chowdhury, Minister of State for Railways.
He was reacting on today's twin blasts in the Bangalore- Guwahati Express at the Chennai Central Railway station, in which a woman was killed and 14 others were injured.
