There was traffic chaos in east Belfast yesterday as a new Glider bus got stuck while trying to navigate a roundabout in Dundonald.

Translink said the vehicle had been using a diversionary route and that engineers helped to move after it became stuck trying to turn around to start a service in the opposite direction.

The company said there were no passengers on board at the time.

"To maintain service frequency, a Glider vehicle, which was not in service, was turning in Dundonald in order to commence service in the opposite direction," Translink said.

"It was operating on a diversionary route/junction that is regularly used by Gliders."

There were long tailbacks for more than an hour while engineers helped free the vehicle.

The £90m Belfast Rapid Transit Glider service, which runs from east to west Belfast became fully operational on September 3.
