Is there a reason that a LA northbound Amtrak cannot go straight into the SP(Caltrains) depot in San Francisco? Maybe even split the train at San Jose between SF bound and East Bay and points north. And do the reverse on the southbound to LA. Does Caltrains (which provides service from SJ-SF) stop Amtrak from doing this? The old SP used to provide service into SF to their depot on 4th and Townsend Sts. And I would guess that direct SF-LA service would entice lots of passengers. Direct service is one of the primary reasons for the high speed rail project which is a long way off. Reviving the old route would be far cheaper and provide direct service in the interim before the completion (As my Uncle Bob used to say "if you live long enough") of the high speed route.
