BUENA PARK, Calif. – Authorities say 10 people have been injured in a rollercoaster accident at Knott's Berry Farm in Orange County.
Fire Authority Capt. Greg McKeown says the accident happened Thursday night on the Pony Express but the injuries were minor.
He says two rollercoaster trains collided in the station where park guests board the ride.
Knott's spokeswoman Jennifer Blazey told the Orange County Register that a train leaving the station didn't make it over the first hill and rolled back into another train.
One person who was getting into a waiting train and nine people on the train that rolled back were injured.
McKeown says the victims were taken to hospitals.
The cause of the accident is under investigation.
