Hypothetically, a relaunch of the "
Spirit of California" overnight train between LA <-> SF could be accomplished in the following fashion:
Once the new California Cars start rolling into service from Illinois;
- Repurpose the CalComets into a dedicated Spirit of California fleet.
- Retain the three Horizon cafes and F-40 NPCU's.
- Purchase five Viewliner sleepers off of the Amtrak order from CAF, as a negotiated exercising of the additional car option.
Run the train as an overnight service with the northern terminus being San Francisco 4th & King station, the southern terminus being Los Angeles Union Station. Serve all stops between the two as is normal for the Coast Starlight.
If the service flops, selling the Viewliners back to Amtrak would mean little risk financially because you know they'd be hungry to use them if given the chance. Especially if they had a 50/50 ownership, where Amtrak could theoretically have the cost shared with California.
What would be the point though? Given priorities, you're competing against the Starlight, the Daylight, another daytime Surfliner frequency at San Luis Obispo, multiple Surfliners at Santa Barbara, and daytime direct rail trips to Los Angeles via San Joaquin and HSR. You're going to have next to no intermediate market and relying on SF to LA alone is a guaranteed failure.
Well, you might be "displacing" one of the Surfliners in such a scenario (768/785 correspond fairly closely to the Spirit of California's schedule), but even assuming you were adding a train on the old Spirit of California's schedule (depart LAX 2045 arrive San Jose 0720/depart San Jose 2300 arrive LAX 0830), you'd probably be ditching a bus that already operates in favor of a train, and there's a decent chance you could add some business on those corridors you'd be "competing with".
Edit: Also, I think you put a bit too much emphasis on the trains competing with one another rather than complementing one another. Multiple trains on varied schedules serving different markets open up additional travel options, for example; if anything, the evidence seems to indicate that running multiple trains helps ridership on all the trains. Likewise, I'd point out that a Spirit of California heading into either San Francisco or Oakland/Sacramento would provide legal connections with the
Zephyr both ways (which the
Starlight does not), as well as with the
Southwest Chief. It would also provide an option to get to San Diego sometime other than 1 AM with a single transfer (and not be stuck on a bus).
