On January 28, 2000, about 5:56 a.m. in Glendale, California, a tractor-combination vehicle, operated by Mercury Transportation, Inc., was transporting an oil refinery condenser unit. The vehicle missed a turn in its planned route, traversed a highway-railroad grade crossing, turned around, and was attempting to retraverse the crossing when it became lodged on the railroad tracks. About 90 seconds later, northbound Metrolink commuter train 901, operated by the Southern California Regional Rail Authority, collided with the vehicle. The engineer, conductor, and four passengers received minor injuries. Total damages were estimated to be over $2 million.
