@skinnylatte There's been proposals to extend the Caltrain tracks to the transit center for decades, but the cost would be enormous. There is some hope that High Speed Rail would pay part of the cost, as it did for Caltrain electrification, but that is (a) unlikely and (b) decades off if it does happen. The reason there's a transit center there in the first place is that it used to be the western terminus of the Key System trains in the first two decades of the Bay Bridge. They never should have taken the tracks off the bridge.
