Lived in LA (or surrounding area) for a decade. One of the reasons I wanted to get out was because of how shit it is to get to/from literally anywhere in the city.

This would definitely help things, but no single train line is going to fix the problem. LA is way too huge and sprawling, and requires a large network of rail to become a viable alternative to cars. And there’s way too many NIMBYs with that Hollywood money in key areas of town to make that happen.
