MONCTON, N.B. - The derailment of 16 CN railcars in Moncton is under investigation.

The cars jumped the tracks as they were entering the rail yard early Saturday.

Of those, ten tankers were carrying crude oil.

The other six were empty automobile carriers.

A spokesman for CN says all of the cars remained upright, but one of the tankers developed a leak.

About 150 litres of oil has since been cleaned up at the site.

No one was hurt.
