Martin Bamford, 30, from Croydon, said he recalled the tram “speeding up”, adding: “Everyone just literally went flying.”Speaking outside Croydon University Hospital, where he was being treated for fractured or broken ribs, he said people were screaming and there was “blood everywhere”, describing the scene as “like something out of a film”. The tram was operating from New Addington to Wimbledon via Croydon when the accident happened at 6.10am.Scenes in the wake of the crash were described as “total carnage” and “like something out of a film” after the two-carriage tram tipped over in heavy rain next to an underpass.Survivors rescued from the wreckage said they recalled the tram failing to brake in its usual place at a bend on the track after speeding up. One said the driver told them he thought he had “blacked out”. Asked what he had seen, Mr Bamford added: “There was a woman that was on top of me … I don’t think she made it at all. She wasn’t responsive. There was blood everywhere.”Asked about the driver, he said: “I asked him if he was okay. He said ‘yeah’. I said to him ‘what happened?’ He said he thinks he blacked out.”The 42-year-old man, from Beckenham, was arrested on suspicion of manslaughter and taken into custody for questioning. His friend Sid Richardson told the Croydon Advertiser: “Dane was a young gentleman who made friends not enemies, peace not war and created love where there was hate.”The way he lived is a life lesson to many of us that knew Dane.”London mayor Sadiq Khan, who visited the scene on Wednesday, warned the death toll “may well increase”.

British Transport Police(BTP) said forensics teams are expected to stay at the crash site until Thursday evening at the earliest and identifying the dead might be a “complex and lengthy process”.A spokesman said: “A 42-year-old man arrested in connection with a derailment in Croydon yesterday has been released on police bail.”The man from Beckenham has been bailed until May while investigations continue at the scene and officers work to establish the circumstances of the incident.” Dane Chinnery, a Crystal Palace fan, was killed while on his way to work at a flood response firmCredit:Facebook Royal Navy veteran Kevin Snow, 57, was on his way to work in central London when the busy service overturned.The father of seven, from Barnsley, south Yorkshire, said the service, which he had been using regularly while working in London, failed to slow down at its usual point coming out of a tunnel between the Lloyd Park and Sandilands stops. Initial findings of the RAIB show that the tram came off the tracks as it was negotiating a “sharp, left-hand curve” with a speed limit of 12mph.An RAIB spokesman said: “Initial indications suggest that the tram was travelling at a significantly higher speed than is permitted.”The last known death of a tram passenger in an accident is believed to have been in 1959. Two passengers and the driver died after a tram collided with a lorry and caught fire in Glasgow.The Croydon derailment is the biggest loss of life on the British tram system since 1917, when a tram running down a hill in Dover killed 11. The tragedy is being probed by BTP and the Rail Accident Investigation Branch (RAIB).BTP assistant chief constable Robin Smith said officers were investigating if the driver of the Wimbledon-bound tram fell asleep at the wheel, alongside “a number of factors”.
