At 15:00 on 16 September 2009 a Red Line Luas tram and a double-decker number 16 Dublin Bus collided at the crossroads of Abbey Street and O'Connell Street in Dublin city centre. The front section of the tram was derailed in the incident and the driver's cabin was crushed flat against the left hand side of the bus. At least 21 people were injured and three were seriously hurt, including the driver of the tram who had to be cut out from the wreckage.
