The Amtrak Crescent, which operates between New York and New Orleans, has reportedly been running late because of congestion on the tracks.
That congestion, the association says, is the result of freight trains being diverted to the same tracks the Crescent uses because of track repairs long the coast.
Service into New Orleans was suspended in the weeks after the storms because of the widespread damage.
