Two people have been injured after a carriage pulled along by a mini train derailed at a theme park in Northamptonshire.
People were injured when the train jolted and threw them in the air
Passengers in the last but one carriage on the narrow-gauge railway at Wicksteed Park in Kettering were thrown into the air as the train halted.
Northamptonshire Ambulance Service said two people were injured in the accident at 1700 BST on Sunday and were taken to Kettering General Hospital with leg and back injuries.
The train, which has been taken out of service, and the 1.5 mile-long track will be examined by the Railway Inspectorate.
Safety procedure worked
Stuart Buchanan, who saw the accident, said: "We were over by the water shoot when we heard this really load clattering noise.
"We turned round only to discover one of the carriages had derailed and all the people were bouncing up and down in the air."
Wicksteed Park spokesman John Roberts said: "The emergency stopping procedure was put into effect right away so it (the train) came to a halt quite quickly.
"Unfortunately the jolt of it coming off the rails did cause injuries to some people."
