Rail crash brings down US road bridge Two freight trains have collided in Missouri, bringing down a road bridge and leaving seven injured. TWO freight trains have collided in Missouri, bringing down a highway bridge and sending seven people to hospital. The collision occurred about 190km southeast of St Louis on Saturday when one train ploughed into the side of another and derailed. The derailed train then knocked down a pillar of the overpass, igniting a diesel fuel fire, the St Louis Post-Dispatch reported on its website. Two vehicles were travelling on the overpass when the accident occurred, local police officer Clay Slipis was quoted as saying. Five passengers in the vehicles and two conductors in the derailed train were injured and taken to hospital. Six of the hospitalised were discharged later while the seventh was "in good condition," according to Slipis. The fire was quickly extinguished and a hazardous materials crew was sent to the scene. It is the second serious train crash in the US in less than two weeks. Two commuter trains collided on May 17 in Connecticut after one of them derailed. More than 70 passengers were injured.
