That's a big weak spot of this scheme. Its designers expect many of its riders to drive to Victorville, but once they get to Victorville, they might decide to keep on going to LV.
Distances from Victorville:
Las Vegas: 200 mi
San Bernardino: 35 mi
Los Angeles: 81 mi
Irvine: 80 mi
So I think that the DesertXPress train company may have to run buses to LAUS, and likely other Metrolink and Amtrak stations in the LA area. There is certainly plenty of precedent for doing so, however. Amtrak California's San Joaquins have Bakersfield as their southernmost point, connecting to LA by bus, because that is faster than using the existing rail route. And Amtrak California runs numerous other buses that connect to trains.
I think that the DesertXPress company is going this route to avoid using El Cajon Pass, which would either slow it down by some sizable factor or else require expensive new construction. The train could also go from Victorville to Palmdale, then follow Metrolink's route: Palmdale - Santa Clarita - Burbank - LAUS.
