COLUMBUS, Ohio (AP) - More than a dozen trains loaded with over 1 million gallons of crude oil cross Ohio every week.
Ohio officials released the information to The Associated Press Thursday after earlier refusing to disclose it.
Federal transportation officials ordered the railroads last spring to notify states about trains carrying at least 1 million gallons of crude oil.
CSX says it hauls 15 to 30 trains a week across some counties and only 1 to 5 trains a week in other places.
Norfolk Southern transports 1 to 14 trains a week across 19 counties.
Canadian Pacific hauls three trains a week across northwest Ohio.
The crude oil trains are being scrutinized after several fiery derailments, including a July 2013 incident that killed 47 people in a small Canadian city in eastern Quebec.
