Associated Press MOBILE, Ala. — Gov. Kay Ivey said Alabama will oppose an Amtrak plan to resume passenger train service between New Orleans and Mobile without a study of its potential impact. While Amtrak asked federal regulators last month to force CSX and Norfolk Southern Railway to let passenger trains run on its track linking the two Gulf Coast cities, Ivey wrote the Surface Transportation Board saying Amtrak should be required to complete a study on the potential impact on freight traffic, WPMI-TV reported. The northern Gulf Coast has been without passenger service since Hurricane Katrina badly damaged tracks and equipment in 2005. While Louisiana and Mississippi have supported a resumption, Ivey wrote that Alabama has withheld funding for new service for several years over concern that Amtrak trains would interfere with freight service at the Port of Mobile.
