摘要

On January 26, 2010, about 1:40 a.m., a hi-rail vehicle-a truck or automobile that can be operated on either highway or rail-operating southbound about 0.9 miles north of the Washington Metropolitan Area Transit Authority Rockville metro station struck and fatally injured two automatic train control technicians who were working on the right-of-way replacing an impedance bond between the tracks. The hi-rail vehicle was traveling down the track in the reverse gear at about 13 mph. The safety issues discussed in this report are the following: Inadequate procedures within the WMATA Operations Control Center for protecting roadway workers; Inadequate procedures within the WMATA Operations Control Center to coordinate work between two separate roadway worker work groups; Inadequate communication between roadway worker work groups; Inadequate Federal agency oversight of roadway worker policies and procedures; and Lack of requirements for automatic backup alarms on hi-rail vehicles.
