One person has been injured and services have been severely disrupted after a passenger train derailed in Norfolk. 

An East Midlands train travelling between Liverpool Lime Street and Norwich derailed after hitting a tree at 90mph between Thetford and Harling Road shortly after 9pm on Tuesday. 

Norfolk police said one person suffered minor injuries.

However, they were not taken to hospital.

A spokesman for the East of England Ambulance Service said: "Two ambulances, four ambulance officer vehicles, the Hazardous Area Response Team and a response car from the East Anglian Air Ambulance were sent to the scene.

"One passenger from the train was assessed for minor injuries and did not require transportation to hospital.”

It is thought 31 passengers, a guard and a driver were on the train at the time. 

It is understood the train remained upright despite derailing with the front severely damaged.

Passengers were evacuated onto the track and on to a replacement train.

Greater Anglia services between Norwich and Ely have been cancelled. 

There is also disruption to East Midland Trains services.

Cancellations are expected all day. 

Eight appliances from Norfolk Fire and Rescue Service were called to the derailment at about 9.15pm.

The crews were from East Harling, Thetford, Attleborough, Watton, Hingham, Wymondham, Diss and Carrow.

They provided scene safety and casualty care.

British Transport Police and Network Rail are investigating.

A stop time was called at 12am on Wednesday.

"Upon attending it was discovered the train had partially derailed at the front after striking a tree, however the carriage remained upright.  All passengers were safely evacuated from the service," said a spokesman for British Transport Police.

A spokesman for Greater Anglia said: “We are sorry for the inconvenience caused and anyone who is delayed by more than 15 minutes is eligible to claim delay repay compensation."

Norfolk Police tweeted: "Our officers are at the scene supporting British Transport Police & Network Rail. One passenger with minor injury looked after by ambulance colleagues but no other injuries. Fire also on scene. Network Rail arranging transport for passengers to complete their journeys to Norwich."

Network Rail said the train has been returned on to the rail lines but remains in place.

Engineers are due to inspect the damage and are waiting for the tree blocking the line to be removed.

An engineer at the scene told BBC Radio Norfolk: “Everyone on board had a very lucky escape.”

It is understood a window at the front of the train has been partly broken. 

The wheels have also been badly damaged and cannot be driven, so it looks as if specialist equipment will have to be brought in to lift it off the track.
