Amtrak says it has asked a federal agency to require that two freight railroads provide access to their rails for the resumption of passenger train service between New Orleans and Mobile, Alabama.

The passenger rail corporation, partially owned by the government, announced plans in February to provide the service for the first time since Hurricane Katrina badly damaged tracks and other railroad infrastructure in 2005. Freight trains resumed running in the area after repairs, but Amtrak service didn’t.
