A “walking pace” collision occurred on the Sonic Spinball rollercoaster at Alton Towers on Tuesday, it has emerged.
The park described the coming together of two ride cars in the loading station as a “nudge”.
It said that it advised that those in the two trains attend its on-site medical centre for “precautionary checks”.
A spokeswoman for the Staffordshire attraction said: “Two cars in the station area nudged each other at walking pace.
“The guests on the two cars walked off and we advised that they attend our medical centre as a precautionary measure.”
The incident has been seized upon by British tabloid newspapers, in the wake of the Smiler accident which occurred 2 June and seriously injured five people.
