Train derailed, two swept from car in Australia floods

A freight train has been derailed and two people were swept from their car in flooding that struck Australia's Northern Territory.

Two crew members were hurt when the freight train was derailed from a bridge near Katherine, south of Darwin.

A man and a woman were also swept from their car on a bridge in the same area, and found clinging to a tree by police.

Heavy rain from Tropical Cyclone Grant, downgraded to a tropical low on Boxing Day, caused the floods.

The driver and co-driver of the train were rescued and are being taken to a hospital in Katherine.

The couple were trying to cross the bridge when their car stalled, according to media reports.

They climbed onto the roof but were carried away by floodwater.

Most of the Northern Territory has been spared the worst of the storm, which developed over the Christmas holiday weekend, media reports say.

But flooding is still a concern in several areas, meteorologists warn.
