This problem can be remedied by having a few trains per hour stop at the King St station. These people will have to board another train to continue to the transit center. This isn't necessarily a bad thing. This train would be less crowded during commute hours, and may even be preferable for those whose final stop is before downtown. It is more likely to be a local train, allowing express trains the priority to just continue their route into the city.

The best long-term solution is to continue to dig under the bay all the way to Alameda Station, build some housing, and continue to Oakland. The train can then split to go North to Berkeley/Sacramento or continue East to the new Oakland A's stadium and Jack London Sq. That would be what a global A-class city would do.

You wouldn't have to build CAHSR north to Sacramento like previously planned, it could simply continue from SF along existing Amtrak lines.
