It does, but that doesn't mean that the major west coast ports have adequate freight rail service.

It seems to me the solution is to have a major rail artery which at least allows freight to be delivered to a distribution center farther inland(Ontario, Palm Springs, or somewhere east). That would free the truckers from dealing with LA freeway traffic.

Another option would be a canal up to the Salton Sea. Obviously that's a much more major effort but it has nearly endless economic and ecological benefits.
