Wasn't a third track recently opened, increasing capacity by 50%? Are you telling me the freight trains have this additional capacity clogged up already? Whether it's Metrolink or Amtrak, I don't envision more than two or three daily round trips through there. I have a very hard time believing this is impossible. I will agree that a full fledged commuter service from Victorville with three peak hour round trips and additional off peak service isn't possible.
I believe DesertXpress isn't crossing the pass because it's not compatible with the existing infrastructure; they're planning on running non-FRA compatible (but UIC-standard safe) EMUs on new track and alignment. They can't run on the FRA-governed, non-electrified BNSF/UP tracks over Cajon Pass, there's no remaining width for another ROW, and they don't want to spend the $N billion to widen the pass (or, more likely, dig a base tunnel under it). The lack of room for new tracks for DesertXpress doesn't necessarily mean that there's no room on the existing tracks for Metrolink, or Amtrak, but I'm sure that that's enough of a chokepoint for both BNSF and UP that they are both happy to continue furthering that confusion.
