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 the 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.
British Transport Police (BTP) were alerted by emergency services.
A spokesman for Network Rail said: "An emergency stop message was sent to all trains in the area but the 6.13 Nottingham to Norwich service with six passengers on board was unable to stop and struck the bridge."
East Midlands Trains announced severe disruptions to its services but other train operators were accepting tickets from its passengers.
A spokeswoman for East Midlands Trains said: "We are providing some road transport in the Leicester, Loughborough, Derby and Nottingham area. But it is a very limited service. We would advise passengers: do not travel unless you have to."
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."
