Investigation into a tram derailment in St Peter's Square, Manchester, on 29 June 2008

The RAIB is carrying out an investigation into the derailment of a Manchester Metrolink tram at St Peters Square, Manchester during the evening of 29 June 2008.

The 22:44 hrs tram from Altrincham, consisting of trams 1008 and 1016, had just departed from St Peter’s Square stop travelling along Mosley Street towards the city centre when the middle bogie of the rear unit derailed to the left at 23:10 hrs.  The tram travelled a further 100 metres before coming to a stop across the junction with Princess Street, with the derailed bogie having partially mounted the pavement.  No other wheels derailed.  One passenger was taken to hospital with neck and back pain. 

The tram damaged its own overhead electrical equipment poles and signal stanchions, and the line was closed until 15:45 hrs on 30 June 2008.

On the basis of a preliminary examination there is no indication that the condition or operation of the tram, or that of the signalling system, contributed to the derailment.

The RAIB's investigation into the derailment is independent of any investigations by the safety authority or the Police.

The RAIB will publish a report, including any recommendations to improve safety, at the conclusion of its investigation.  This report will be available on the RAIB website.
