A train which crashed into a sewage tanker on a level crossing will be moved today as engineers work to reopen the line.
Twenty-one people were injured after the first of the service's two carriages derailed at Little Cornard, Suffolk, on Tuesday evening.
A 58-year-old man who was a passenger on the train remained in a "critical but stable" condition with abdominal injuries.
The 1731 National Express East Anglia service, which was carrying about 20 passengers and thought to have been travelling at between 50mph and 60mph, cut the tanker in two as it made its way from Sudbury, Suffolk to Marks Tey, Essex.
The tanker driver - a 38-year-old man from Cambridgeshire, who was unhurt - has been arrested on suspicion of dangerous driving and is still being questioned.
Police officers searched the crash site yesterday as engineers prepared to move the damaged carriages with a crane.
Network Rail said the two track stretch of line was not expected to open before Friday.Reuse content
