There were no serious injuries.<br /><br />"Most of the people were complaining of either neck pain or back pain," Forest Park Mayor Anthony Calderone told the CLTV news station, according to Reuters.<br /><br />Investigators are trying to determine the exact cause of the incident.<br /><br />"The million dollar question is, how did this happen?" Robert Kelly, Amalgamated Transit Union President Robert Kelly, told reporters. <br /><br />Kelly noted the blame appears to lay with a mechanical malfunction, but as a precaution, police are treating the station as a crime scene. <br /><br />"If it wasn't a goof or there is someone not telling us something that creates a big problem because if one train can start moving without anybody doing anything than it can happen to another train," said Mr. Kelly, according to a different report by the Houston Chronicle.<br /><br />--------------------------------------------------------<br /><br />TomoNews is your daily source for top animated news.
