(CNN) -- Ten adults and children were hospitalized Wednesday after an amusement park ride in Colorado overturned, officials said. None of the injuries were life-threatening.
The incident happened at the Tiny Town amusement park in Jefferson County, area sheriff's spokeswoman Jacki Kelley told CNN.
It appeared that the engine portion of the train tipped over, followed by several of the cars that were carrying visitors to the park, Kelley said. The train moves very slowly, she said.
The sheriff's office was investigating the incident.
There were 18 people who were evaluated for injuries, and 10 of them who were transported to the hospital, Kelley said.
The park was closed due to the accident.
In addition to the Jefferson County Sheriff's Office, four area fire departments responded to the scene.
Tiny Town bills itself as "the oldest kid-size village and railroad in the U.S.A."
