Unfortunately no such service exists.The only train route between cities in the US is operated by Amtrak.They serve both Atlanta and Dallas, but there s no direct route between the two, much less a non-stop route. You d have to first take a train from Atlanta to Washington, DC. Then you d take a second train from Washington to Chicago. And then you d take a third train from Chicago to Dallas.The cost would vary based on when you actually travel, but it will be somewhere between $350 and $450 and the trip would take about two days actual traveling time.I doubt that you re still interested, but if you are, here s a link to Amtrak s website. You d be going from city ATL to city DAL.http://www.amtrak.com
