A train speeding through a seaside rail station plowed into a group of youths taking a shortcut across the tracks to get to a beach party, killing at least 12, injuring 14 and turning a festive night meant to welcome the start of summer into one of carnage and tragedy, AP quoted officials and witnesses as saying today. It was Spain's deadliest train accident since 2003, when 19 people died in a collision between passenger and freight trains in the southeastern town of Chinchilla. The youths _ at least some of them described as Latin American immigrants _ got off a commuter train in the beach resort of Castelldefels outside Barcelona shortly before midnight Wednesday to head to the party. About 30 climbed down off the platform and tried to scurry across the tracks instead of using an underpass to leave the station, witnesses said. -- SPA
