Six men and one woman died in the Croydon tram crash, British Transport Police said.
The driver of a tram that crashed killing seven people in south London has been released on bail, they added.
The 42-year-old man, from Beckenham, was arrested on suspicion of manslaughter after the tram flipped on its side in Croydon during the morning rush hour on Wednesday.
He was bailed until May while the investigation continues, British Transport Police (BTP) said.
Investigators said the tram was travelling at a “significantly higher speed than is permitted” and are probing whether the driver had fallen asleep.
More than 50 people were injured when the vehicle left the track.
Dane Chinnery, 19, a Crystal Palace fan described as a “friendly, genuine lad”, was among those killed.
Tom Dale, 20, was on the tram and said he recalled nodding over to his old school friend Mr Chinnery, who was already sitting on the tram when he boarded.
The pair, who went to Addington High School together and took part in performing arts, were on their way to work.
Mr Dale said that after the tram crashed he was looking for his friend, and asking, “Where’s Dane? Where’s Dane?”, but all he could see was Mr Chinnery’s boot where he had been sitting.
“It was like walking out of a war zone,” the chef said.
Mr Dale, who was badly bruised, said of Mr Chinnery: “He was just a friendly, genuine lad, did no harm to nobody, really. No one deserves for this to happen to them.”
Crystal Palace issued a statement on behalf of manager Alan Pardew, chairman Steve Parish, the players and club staff offering their “sincere condolences to the families of those who lost their lives”.
Social media users were encouraged to share a post calling for a minute of applause at the team’s next home game on November 19.
The post said: “He was red and blue all the way through, and simply loved palace.”
It concluded: “RIP Dane.”
Some 38 of those injured were treated at Croydon University Hospital.
One patient remained in the hospital overnight but it is hoped they can be discharged on Thursday.
Dr Nnenna Osuji, medical director of Croydon Health Services NHS Trust, said the day of the accident was “distressing” and led to “very challenging circumstances” for the hospital staff.
London mayor Sadiq Khan, who visited the crash scene on Wednesday, warned the death toll could increase.
BTP said forensics teams are expected to stay at the crash site until Thursday evening at the earliest, and identifying the dead may be a “complex and lengthy process”.
The tram was travelling from New Addington to Wimbledon via Croydon when the accident happened at 6.10am.
Scenes after the crash were described as “total carnage” after the two-carriage tram tipped over in heavy rain next to an underpass.
Survivors rescued from the wreckage said the tram failed 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”.
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”.
He 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 driver was arrested and taken into custody for questioning.
The crash is being probed by BTP and the Rail Accident Investigation Branch (RAIB).
BTP Assistant Chief Constable Robin Smith said officers were also investigating “a number of factors”.
Initial findings of the RAIB show the tram came off the tracks as it was negotiating a “sharp, left-hand curve” with a speed limit of 12mph.
A spokesman said: “Initial indications suggest that the tram was travelling at a significantly higher speed than is permitted.”
Bernice Rooke, 66, has lived next to the tram tracks in Croydon for 15 years and said she has “never heard it so quiet” as on Thursday.
She said: “The first thing you notice is the stillness. Usually it’s mayhem out here in the morning – buses, cars, trams, kids.
“Yesterday it was chaos, sirens everywhere, it seemed like there were hundreds at some points.
“I knew something was wrong when the noise stopped near my house. But today is different, like nothing else here before.”
Dozens of floral tributes have been left near the scene by well-wishers.
One bouquet was left with a card that read: “To the families of all the lives lost. My deepest sympathy from a Croydon resident and my family. RIP. God Bless xxxx.”
