AAL Fremantle was unloading its cargo of cars at berth 11, North Quay. Due to the wind the rope at the stern snapped. This resulted in swinging the vessel out into the port.
“Although the mooring lines at the bow of the ships held good, the ships swung out at the stern. The stern of AAL Fremantle came in contact with scaffolding on the Fremantle Rail Bridge and one of the power poles on the bridge subsequently fell into the harbour," was said in a statement by the Fremantle Ports.
The Public Transport Authority (PTA) has closed the rail bridge to assess the damage. David Hynes, official with the authority, added:
"We're able to run trains down as far as North Fremantle, so trains will continue as normal to North Fremantle and we'll have replacement buses running between North Fremantle and Fremantle itself."
According to the Fremantle Ports, both cargo vessels have been towed back and an investigation has been launched into the incidents.
