BERLIN - AUGUST 20:  An employee of German rail carrier Deutsche Bahn oversees a departing train at Hauptbahnhof main railway station August 20, 2006 in Berlin, Germany. The country is on high alert after suitcases found on commuter trains near Cologne and Dortmund were discovered to contain powerful bombs that would have detonated had it not been for a technical failure in their construction. A Lebanese man is confirmed as one of the bombers and was arrested yesterday in Kiel. Railway officials have said they will beef up security by increasing the number of surveillance cameras and performing spot inspections of baggage. (Photo by Sean Gallup/Getty Images)
