Similar to Black Box, Indian Railway has started installing Loco cab audio-video recording system (LCAVR) / Crew Voice/Video Recording System (CVVRS) in Diesel and Electric locomotives. This system provides invaluable data to investigators which will help them in understanding the sequence of events leading up to an accident and for identifying operational issues and human factors. 26 locomotives (23 Diesel and 3 Electric) have already been installed with LCAVRs/CVVRSs. 100.40 crore has been sanctioned in Budget 2018-19 for the acquisition of 3500 LCVRs/ CVVRS.
