ROSWELL, N.M. (AP) — The National Transportation Safety Board is recommending that railroad companies install video and audio recording devices in their train cabs to monitor the activities of crew members to ensure safe operations. The board during a meeting Tuesday in Washington, D.C., also recommended that federal railroad regulators find ways to prevent collisions like the one in eastern New Mexico in 2015 in which an engineer was killed and a crew member was seriously injured. The two crew members had jumped from their Southwestern Railroad train before it struck a parked train on a siding near Roswell. Investigators say a crew member of the parked train failed to reset a track switch before going off duty. The board acknowledged the lack of adequate warning systems, noting that failure to reset manual switches is a known high-risk hazard.
