CN spokesperson Warren Chandler told local news outlet the Edmonton Journal Thursday that 11 cars left the tracks at about 12.30pm local time Tuesday when the train collided with a stationary CN train.
The name of the injured worker was not released, though he remained hospitalized in unknown condition at press time.
Chandler would not elaborate on the origin or destination of the train, and couldn’t confirm how or why the collision occurred, citing the company’s investigation.
It is also unknown how much coal was lost when the cars left the tracks.
Railroad officials were on scene Thursday and the Transportation Safety Board of Canada has commenced its investigation into the accident.
Canadian National Railway is the nation’s largest coal and freight shipper.
