"A mile-long train hauling oil from Canada derailed and leaked 30,000 gallons of crude in western Minnesota on Wednesday, as debate rages over the environmental risks of transporting tar sands across the border."
"The leak -- the first major spill of the modern North American crude-by-rail transit boom -- came when 14 cars on a 94-car Canadian Pacific train left the tracks about 150 miles north west of Minneapolis near the town of Parkers Prairie, the Otter Tail Sheriff's Department said.
Canadian Pacific Railway Ltd, the country's second-largest railroad, said the company was investigating the incident. CP Spokesman Ed Greenberg said only one 26,000-gallon tank car had ruptured, adding it was a mixed freight train carrying crude and other materials.
The company did not comment as to what kind of crude the train was carrying."
