About 150 litres of oil spilled when a number of rail cars derailed Saturday morning at CN's Gordon Yard in Moncton, a CN spokesperson says.

Louis Antoine Paquin says the train derailment happened at about 12:20 a.m.

There were 16 cars on the train, all remained upright. Ten were carrying unrefined crude oil, while the remaining six were empty cars that are used to transport vehicles.

The leak was quickly plugged and the clean up is complete, said Paquin. 

Paul Bruens, a platoon chief with the Moncton fire department, said they weren't informed of the derailment until 7:45 a.m. 

"They requested us for their assistance on a standby mode while they transferred fuel from a damaged rail car into an undamaged rail car," he said. 

Bruens said the incident happened on private property, away from homes and businesses.

No one was injured.
