The Bombay High Court on Wednesday asked railways to upgrade its system so as to prevent crime against women in local trains and on platforms and consider forming an expert committee to study advanced technologies globally.

"The CCTVs on platforms and other places are of outdated technology. It does not help prevent crime. You (railways) should upgrade to better technology. Consider forming an expert technical committee which would study technological advancements across the world and give suggestions," a division bench of justices N H Patil and S B Shukre said.
