Three tanker cars in an oil train from North Dakota derailed at a rail yard in Seattle early Thursday, but Burlington Northern Santa Fe says none of the oil spilled. According to AP, Gus Melonas says a locomotive and buffer car loaded with sand also left the rails about 2 a.m. at the Interbay yard as the train with 102 cars of Bakken oil was pulling out, headed for a refinery. The BNSF spokesman says the train was traveling at about 5 mph at the time. Two of the tankers are leaning, and one at a 45-degree pitch will be pumped out. It holds 27,000 gallons of oil. No one was injured. Melonas says crews expect to have the cars back on the rails and the track repaired by midnight Thursday.
