Are you talking about the ATL station? There are trains Saturday night and Sunday night. How can they be closed?This has been a hinderance to taking the train on more than one occasion (and not just in ATL). It's a darn shame, too.The only drawback is that the office is closed on Sunday and closes around noon on Saturday.
Go back and read Dovecoat's original complete statement. He is talking about an Enterprise Rent a Car place near the station, not the station itself.
