It's not every week that two bridges collapse only days apart. This time, seven people are injured after after two trains collided and knocked out a bridge's support pillar, triggering its collapse. Two cargo trains T-boned each other around 2:30 a.m. Friday night in Scott County, Missouri, according to KFVS 12. A Union Pacific train slammed into a a Burlington Northern train, derailing the Northern Union train and sending it straight into the bridge's support pillar. "One train T-boned the other one and caused it to derail, and the derailed train hit a pillar which caused the overpass to collapse," Scott County Sheriff spokesperson Clay Slipis
