PORTLAND, Ore. — Reports to the state show the volume of oil hauled on railroads in Oregon increased last year to more than 11 million barrels.
That's up from about 3 million barrels in 2012.
The Oregonian reports Burlington Northern Santa Fe and Union Pacific reported the figures to the Oregon Department of Transportation.
Most of the tanker cars are moved through Portland to a terminal near Clatskanie that loads oil on barges bound for West Coast refineries. Oil trains also pass through the Columbia River Gorge, Salem, Eugene, Bend and Klamath Falls.
Oil train shipments through the Northwest are expected to grow as they carry crude from the oil boom in North Dakota.
