It's very charitable to describe Phoenix as served by Maricopa station, even indirectly. It's 45min/30mi away on the other side of a mountain range in the middle of the desert. It's not even in the same county.
Honestly, no. That's the distance from the close parts of the city. The equivalent for LA would be Union station being out in Palmdale. The farther parts of the MSA and traffic can add 1-2hrs to that time.
LA is pretty well covered overall though, at least by West Coast standards. The biggest hole in the train network is long beach, but there's a lot of transit development happening in that area nowadays.
