BBC helicopter footage of the scene
Several people were injured when a cement mixer lorry fell from a bridge and landed on a train at Oxshott, Surrey.
The vehicle landed on coaches of the 1505 South West Trains passenger service from Guildford to London Waterloo just after 1500 GMT.
Two people are reported to be trapped in the wreckage with injuries requiring medical attention.
The lorry driver is also thought to be seriously hurt.
A Surrey Fire and Rescue spokeswoman said: "Two people are medically trapped, meaning they need to be stabilised before they can be taken off."
A British Transport Police spokesman said a total of 36 people were on the train, four of whom were injured, one seriously.
The lorry is believed to have struck the fourth carriage of the eight carriage train, punching a large hole in the metal roof.
Emergency services are at the scene, including six ambulances from the South East Coast Ambulance Service.
The crash occured on a branch line in north Surrey
A Network Rail spokesman said: "So far there are no reports of fatalities though it is believed there are several people injured."
Eyewitness Nikki Karim works in a taxi office near to the crash site.
She said: "There's a lot of police at the station, there's a few minor casualties that are sat at the platform."
She added: "You don't expect this sort of thing to happen."
The incident took place on a branch line, and is unlikely to result in major disruption.
