MONTREAL (AFP) - An oil-bearing train derailed and ignited in western Canada on Saturday, just months after the massive Lac-Megantic catastrophe highlighted the danger of transporting fuel by rail.

Officials said the fire has not yet been contained in Gainsford, a town some 80km west of Edmonton, after the 13-car Canadian National train derailed.

The train carrying crude and liquid gas left the track for unknown reasons at around 1am (1pm Singapore time), federal transport officials said.

Canada's transportation safety board said no one was believed injured in the accident.

Chris Krespki, a spokesman for the board, told media an investigation is underway.

In July, a train carrying crude derailed in Lac-Megantic in Quebec, setting off a huge explosion that killed 47 people and caused massive damage.
