Television footage showed several train cars lying on their side amid flames and swirls of black and white smoke, with the remains of a truck that, according to reports, may have tried to cross the tracks as the train passed. The Baltimore County Police and Fire Department said there were no early indications of casualties, but it posted on Twitter that preliminary reports show "several buildings collapsed at site of train derailment." The Maryland Transit Administration said the train, operated by freight carrier CSX, derailed around 2:15 pm (1815 GMT) near Rosedale, Maryland, and travel delays are expected as authorities juggle schedules to accommodate commuter trains. The force of the explosion appears to have blown away the facade of some structures near the tracks, according to live images on WBAL television. Amateur video believed to depict the aftermath of the derailing showed flames soaring more than 70 feet (20 meters) into the air, followed by a huge explosion. The National Transportation Safety Board said it was monitoring the incident.
