BuzzSaw blues as ride gets stuck

Dreamworld engineers will give the park's BuzzSaw rollercoaster a once-over after it stopped, briefly stranding 12 thrill seekers on Friday.

A safety sensor was activated on the ride around 11.30am.

The theme park's Facebook page said it was unclear what caused the glitch.

"As per standard operating procedures for safety sensor auto-stops, the ride will be inspected by engineers and retested, before it reopens," the statement said.

"Auto-stops occur for a variety of reasons, from safety sensor alignment to guest behaviour or weather."
