A Newport Beach company, called "Dreamstar Lines", is proposing a new "Lark" train from Los Angeles to San Francisco. The train would leave LA at 10 PM and arrive in SF at 8:30 AM. A roomette would cost around $300 for a one-way trip. Dreamstar Lines would like a startup by the summer of 2024 (good luck!). If the new passenger does come about, why not extend the route to Sacramento, and even further north to Redding or Klamath Falls. A daytime passenger train, northbound from the Bay Area, would be great.

Going north from the Bay Area turns it into the "12-hour offset" sister to the
Coast Starlight proposal, which has been talked about since the 1970's. Times might be jiggled some to make connections, but Portland is the only major market that falls into a bad timeslot. And as PDX and SEA stations are both handy to major sports facilities, there is some late night potential. Fans in the region are already used to the trains for afternoon games. Or, 1970's European style, the new train might stop in Oregon City and Vancouver, WA, with the Portland Union Station closed in the middle of the night.
The problem with this from the California perspective is that southbound schedule reliability would suffer, and it would not go into SF, unless an SF section from LA were to be added. On the other hand, with the current federal legislation, it would be an Amtrak responsibility,
Which means nothing will happen.
A complementary service would be to extend the
San Joaquins Trains 711 and 718 into Los Angeles via Barstow and San Bernardino. I think it would sell a lot of coach tickets, even without leg-rest seats. Given the tendencies of the JPA for this route, I think that idea will gather dust, too.
