While many questions are yet to be answered about how this morning's Norwich train crash happened, some details of the incident are starting to emerge.

The Greater Anglia train left Yarmouth station at 11.34pm with 31 passengers, the train driver and conductor onboard.

As it arrived into platform six at Norwich train station, two empty East Midlands Trains were stationary in the station having completed their journeys.

For a reason that is still to be determined, the Greater Anglia train shunted into one of the East Midlands Trains, causing that to shunt into the second one.

The train did not derail and while the crash took place at 'low speed' the impact was strong enough to injure eight of the passengers. Both the train driver and conductor were unhurt and will be helping out with the investigation.

Crews from the British Transport Police, Norfolk Fire and Rescue, the East of England Ambulance Service Trust (EEAST) and Norfolk Constabulary attended and of the eight hospitalised, four were put on a stretcher to be taken to the Norfolk and Norwich University Hospital.

All have since been released, so minor were their injuries.

Greater Anglia despatched its own emergency team to Norwich train station and the remaining 23 passengers were looked after by them until they were able to be taken home.

The Greater Anglia train is now back at the Norwich depot, where it is being assessed to see if any repairs need to be made.

Jonathan Denby, head of corporate affairs, explained that it was too early to determine what caused the crash and whether it was a case of human error or a technical fault.

The incident has now been handed over to the Rail Accident Investigation Branch, which has launched an investigation.

Trains from Norwich station were today running as normal, with little sign of this morning's drama evident there.
