Croydon tram was three times over speed limit
A tram which crashed in Croydon killing seven people was travelling at three-and-a-half times the speed limit, the Rail Accident Investigation Branch has said.
The train was running from New Addington to Wimbledon when it derailed on 9 November at 6:10am.
The Rail Accident Investigation Branch's (RAIB) initial review of the on-tram data has shown the tram was travelling at a speed of approximately 44mph as it entered a curve.
The speed limit on that particular section of track is 12mph.
Six men and one woman died, and more than 50 people were injured.
The investigation has found no evidence of track defects or a malfunction of the tram's braking system.
Investigators also revealed the tram travelled for 25 metres on its side after overturning.
A full report will not be completed for many months.
Dane Chinnery, 19, Philip Logan, 52, Philip Seary, 57, and Dorota Rynkiewicz, 35, were all killed in the crash.
Robert Huxley, 63, from New Addington, Mark Smith, 35 and Donald Collett, 62, both from Croydon also died.
The tram's driver, Alfred Dorris, 42, was arrested at the scene and was questioned on suspicion of manslaughter.
Mr Dorris from Beckenham, south London, has been bailed until May.
The RAIB issued "urgent safety advice" to First Group, which carries out the day-to-day operation of the trams, and Transport for London.
Both organisations were urged to take measures to reduce the risk of trams travelling "at an excessive speed" once the line is reopened.
Chief Inspector of Rail Accidents Simon French said he would be in contact with the casualties and the families of those who died, and said they would investigate previous reports of speed on the line.

He said: "Our ongoing detailed investigation will now look at the wider context of the accident, including the sequence of events, the way the tram was driven, the infrastructure and how people received their injuries.
"We will also be looking into previous occurrences of over-speeding in this area and underlying management issues."
Transport for London (TfL) has since offered to pay for the funerals of the seven victims of the crash.
