DFW has the TrAAin not the "TrAAm" get it right! ****TrAAin!!!****... A friendly big airport that always has delays during which you can ride around on AA's TrAAin and kill some time until it breaks down on you like it always does and your stuck there for 20 minutes killing more time. Sometimes, the TrAAin just stops working before you even get on it :( in which case prepare to be directed by angry fat people to the moving walkways.
DFW is replacing their world-class TrAAin from 1912 with the new SkyLink/SkyTrain whatever in July 2005.
