An investigation continues today to discover why a guided bus came off its tracks in Trumpington yesterday, injuring five people.
The guided bus left its tracks near Foster Road in Trumpington just before 2pm. It had been travelling towards Addenbrooke's and had left its tracks, crossing a busy cycle lane, before coming to rest in a verge, very close to a bus stop.
Sean Harrison-Fuller is the busway team leader for Cambridgeshire County Council.
He said: "We don't know what caused it yet. When I arrived on the scene, there were three walking wounded in evidence.
"The ambulance came and took another two people to hospital. I don't think their injuries were life-threatening. They were conscious and breathing. They were elderly, so I think they wanted to be careful.
"The bus is still movable. There are cameras on the bus, and this is what they're for."
Mr Harrison-Fuller said there would be a 10mph speed limit in place in the area until damage to the track was repaired.
At that particular part of the busway, he said buses could be doing a maximum of 56mph. He did, however, say this kind of accident could easily occur at 20mph, if the conditions were right.
After the accident, the busway was closed in both directions, with buses being diverted away from the area. The busway reopened a little before 7.30pm, with a 10mph limit in place until work to repair damage caused to the track during the crash can be repaired.
Two people have been taken to Addenbrooke's Hospital in Cambridge. One is a woman with a hip injury and the other, a man, suffered a back injury.
Three other passengers were described as walking wounded and were assessed at the scene. They did not require hospital treatment.
A spokesman for the East of England Ambulance Service said: "Neither of the people taken to hospital has life-threatening injuries. We sent two ambulance crews and our hazardous response team to the incident."
A Cambridgeshire County Council spokesman told the News: "Following the incident this afternoon on the busway, a diversion has been put in place while investigations begin and the vehicle is recovered.
"We will be working with Stagecoach to understand how this incident occurred."
It comes after Manchester sought advice from Cambridge on its own guided busway, due to open in April.
County councillor Mike Mason said: "I would sincerely hope that the City of Manchester receives honest answers on operation of guided buses in the Cambridge sub region.
"While the number of passenger journeys might indicate success, the financial losses for the taxpayers of Cambridgeshire continue to mount up daily as I advised at council during the recent budget debate.
"The blue and green buses in Cambridge, St Ives, Huntingdon and Peterborough spend hours crawling through congested peak hour traffic with accidents at junctions and structural guideway failures ever increasing.
"This congestion is predicted to worsen yet the service operators choose not to run Sunday or late evening services using the
expensive guideway, tunnel and bridges built between Cambridge station, Addenbrooke's and Trumpington."
