LAX is out of the way of the HSR line. The Green Line of LA Metro Rail misses LAX by about a mile - in the early 1990s when the Green Line was being built LAX parking companies lobbied successfully to prevent the line from going to the terminal. Metro has long wanted to rectify that mistake and has plans to connect the Green Line directly to the terminal.

The other end of the Green Line was to terminate in Norwalk, which is slated to get an HSR station. The Green Line wasn't completed to Norwalk but falls about 2 miles short. HSR could provide the impetus to finish the Green Line at both ends.

It's worth noting that Millbrae/SFO is going to be an HSR stop, which is connected by a brief BART ride to the SFO terminal, and will come within a mile and a half of the San José airport terminal. The San Diego terminus might be at the airport there, depending on the final routing decision (the specific routing of the SD branch should be treated as theoretical at this point).

And the world will live as one
