AUSTIN, Texas (AP) – As many as 10 trains weekly have been coming into Texas carrying a million gallons or more of Northern Plains crude oil that’s been involved in fiery derailments in the U.S. and Canada.

Details on the shipments were released Friday by the Texas Attorney General’s Office under a public records request from The Associated Press.

They show BNSF Railway hauling up to six trains weekly into the Houston area. The Fort Worth-based railroad reported two to four trains weekly along a second route through Tarrant and McLennan Counties.

Kansas City Southern Railway reported hauling up to one train a month into Nederland, Texas.

A train carrying crude from the Bakken region of Montana and North Dakota derailed and sparked a spectacular fire last week in West Virginia. Hundreds of families were forced to evacuate.
