I don't recall the details on the bus bit, but on the train bit, someone upthread explained and it was right -- the 1 hour was from Union Station to Irvine, then it was adding a bus link from Irvine to San Diego. But that didn't show in the "select a train" area, it only showed when I selected and then viewed in my itinerary/cart. More my confusion, I think, as an infrequent Amtrak'er. Still bummed, that San Diego run is one I use several times a year, just not this weekend!
