The Wiki is great and I see that scanning the ticket on the train is the key. Am thinking of getting off at Trenton instead of going to 30th Street (ZFW).

What I find interesting is the cost of the flights I'm looking at. My plan now is MEL-LAX (open jaw) DEN-PHL ZFW-EWR-LAX-MEL. Since it already has an open jaw out west, removing ZFW added $200 to the flight. So, it's like getting paid $200 to take the train.
