There is no real train station in San Francisco: you're insane if you think that the Caltrain station could move significant fractions of the traffic that SFO does. SFO is more convenient to a much larger percentage of the people who live in the area (sure, not the strict city limits of SF proper) than a hypothetical station in downtown SF would be. Like, this is pure fantasy. It's just people who have some kind of weird identity built up out of "liking trains" ignoring the actual world. I said, "there's about a 20-40 minute advantage to train stations" and you're like trying to go to bat for the idea that an intracity commuter station which is 12 minutes from the airport somehow disproves that.
