A train driver has been seriously injured when he became trapped in his cabin after hitting a footbridge.
An engineering works tipper truck had struck the bridge, sending it falling into the path of Friday's oncoming 6.13am Nottingham to Norwich service.
The incident - near Barrow Old Station in Barrow upon Soar, near Loughborough, Leicestershire - happened at 6.32am.
Six passengers were onboard the Midland Mainline Nottingham to Norwich service at the time and one suffered minor injuries. They were able to continue their journeys by cab.
The driver was released from his cabin and the train was described as "upright". The lorry driver was trapped in his cab but was freed by fire crews.
East Midlands Trains announced severe disruptions to its services but other train operators were accepting tickets from its passengers.
Association of Train Operating Companies communications manager John Dennis said: "Because the train was too near to be stopped by signalling, it ploughed into whatever debris there was. The train is upright. The passengers have been evacuated without injuries. There is no estimate on when normal services will resume, but clearly it will take a while."
Initial examinations of the site have shown there was no fault with the train, tracks or signalling system.
A spokesman for the Rail Accident Investigation Branch said: "On the basis of a preliminary examination there is no indication that the condition of the train, the track, or the signalling system caused the derailment. The ongoing investigation will focus on the circumstances of the lorry striking the bridge and the "crash-worthiness" performance of the train post derailment."
It also confirmed two workers on the site received medical treatment but no passengers were injured.
