Here's the link on rail usage at Los Angeles/:ong Beach

Perhaps other ports are better. You have a valid point about what distance and speed of delivery make rail or trucks a better choice. Some of the recent rail changes have sped up the route through the cities. I know that there are hge warehouse facilities in neighboring counties, such as the facilities in the city of Banning. Presumably these are rail delivery and distribution facilities.

Oakland has a much lower train usage at its port (10% vs 50% for Los Angeles) I know there's an inconsistency between my reported 35% and this. The supply chain crisis seemed a perfect storm with empty containers piling up in the ports awaiting transport back to the Far East and the ships they were to go on were waiting offshore for space to unload their containers.
