Andrew Braddock is director of UKTram, the UK's trade body for tram operators. 

He says trams are more like a "bus on rails" than a train as there are no signals to indicate when to slow down.   

The Mayor of London, Sadiq Khan, said: “I want to pay tribute to the tireless work of the emergency services, NHS staff, transport workers and Croydon Council which carries on following yesterday’s tram derailment in Croydon. 

“Today, the Union Jack flag at City Hall has been flying at half-mast as a mark of respect for all those who lost their lives or were injured in the incident. 

“My team continues to work with Croydon Council to find the best way to provide immediate help and support for those most affected.

“Investigations into what caused this tragic incident continue, and it is vital that we learn the lessons as quickly as possible to prevent anything like this from happening again.”

The death of a former pupil in the Croydon tram crash leaves Meridian High School "heartbroken", the headteacher says.

The British Transport Police has said following the tram derailment in Croydon yesterday, it can confirm six men and one woman died.

"We are working with the Coroner to identify these seven people and their families are being supported by specially trained officers.

"We remain at the scene, where investigations and forensic work continue," said a spokesman.

Prince Harry joined his grandfather, the Duke of Edinburgh, where they visited the Field of Remembrance and observed a two minutes' silence at Westminster Abbey.

The pair met veterans from past and more recent conflicts, and Prince Harry also managed to share a joke with a young member of the congregation.

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 today.

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".

Disruption to trains between Bedfordshire, Hertfordshire and London could last until Friday, Network Rail says.

London Assembly member for Croydon and Sutton, Steve O'Connell, said the yesterday's tram derailment was the "single biggest tragedy"  in living memory for the town.

“Today the whole of Croydon is in mourning as we try to come to terms with the single biggest tragedy in our community in living memory. 

“Having visited the scene of the crash yesterday, I’d like to express my sincere gratitude to the emergency services for the work they carried out under what must have been harrowingly difficult circumstances.

 “As the names of the victims begin to emerge, it is so important that our community comes together and supports the friends, families and loved ones of all those affected. 

“In time I will be doing all I can to ensure this incident is fully investigated and that we rightly get answers over how this appalling tragedy unfolded.”

A West Ham fan behind a parody video, which shows supporters welcoming a black man onto a train, says he made the video to show that not all football fans are racist.

The video spoofs the recent alleged racist incident on the Paris Metro where a black man was apparently prevented from boarding by Chelsea fans.

Aaron, the man behind the West Ham video, said he believes football cannot tackle racism "on its own" and that the "mindset" needs to be addressed in "schools and colleges", as well as viral parody videos.

Arsenal manager Wenger tells Pat Murphy his side gave themselves "a mountain to climb" after a disappointing performance against Stoke seen them go 3 goals down in the first half.

Stoke's three first-half goals stunned the Gunners who staged a brilliant yet unsuccessful fightback at the Britannia Stadium.

Peter Crouch slotted in after only 19 seconds, before Bojan sidefooted in the second and Jon Walters crashed in to make it 3-0 on the stroke of half-time. Santi Cazorla scored from the spot and Aaron Ramsey volleyed in from a corner soon after to give the London side hope. But Calum Chambers was sent off after a second yellow late on as Stoke held on.
