This could be interesting. If you're a New Orleans Saints fan living in the Gulf South, a new way to get to games this season just opened up to you with this week's Amtrak Mardi Gras Service announcement. Twice-a-day passenger trains will travel between Louisiana and Alabama with four stops in Mississippi beginning Monday, Aug. 18, just in time for football season, but the day after the Saints' preseason home game with the Jacksonville Jaguars. The move revives service that ran for decades before Hurricane Katrina.
