In 2000, the Maryland Transit administration experienced two similar accidents in the same location just 6 months apart. Both accidents involved the failure of a light rail vehicle train to stop at the designated stopping point at the Baltimore-Washington International Airport Light Rail Station (BWI Airport Station). The Safety Board's investigation of the two accidents indicated that, although the direct cause of each accident was different, aspects of the Maryland Transit Administration rail transit operation common to the two accidents influenced both their outcomes. The first accident occurred about 2:37 p.m. on February 13, 2000, when Maryland Transit Administration train 24, en route from Baltimore to the BWI Airport, struck the hydraulic bumping post at the terminus of track No. 1 at the BWI Airport Station and derailed. The second accident occurred about 7:14 a.m. on August 15, 2000, when Maryland Transit Administration train 22, en route from Baltimore to the BWI Airport, struck the hydraulic bumping post at the terminus of track No. 2 at the BWI Airport Station and derailed. The safety issues discussed in this report are the adequacy of requirements governing the use of prescription and over-the-counter medications by light rail vehicle operators, the effect of sleeping disorders on the performance of light rail vehicle operators, and the adequacy of the event recorders. As a result of its investigation, the Safety Board issued safety recommendations to the Federal Transit Administration, U.S. rail transit systems, and the Maryland Transit Administration. |
