We have no idea how it happened. What we have been told is that there is a steep, quite a bad bend so the tram may have derailed but at the moment that is all speculation.

It’s unbelievable that this has happened; it’s unprecedented really since the tram opened in 2000. 

We haven’t had an incident of this scale for some time.

Peter McKenna, Deputy Director of Operations at London Ambulance Service detailed their response.

He said 22 ambulance crews, 12 officers, and two advanced paramedic practitioners were sent to the scene, alongside the hazardous area response team.

Two trauma teams from London’s Air Ambulance and a command support vehicle were also dispatched.

“We have treated a number of patients at the scene and took 51 patients to hospital. Twenty were taken to St George’s University Hospital and 31 to Croydon University Hospital.

“We remain on scene, supporting our emergency service colleagues as they deal with this incident.”
