Even with the rate the world is advancing technology wise I don't think this will be possible within the next 4-5 generations. The infrastructure needed and how/where to build it without impeding current distribution is mind-bottling.
Not going to tackle the tube to Asia, neat idea but there are three tectonic plates moving in three different directions between Asia and the west coast. Two if you go through Japan.
Trains, not going to happen for a long damn time, even with a hyperloop track next to every set of train tracks in the country...you would still need the hyperloop equivalent of a train yard in EVERY location that currently has a train yard and the space to build them. If you've never seen a large train yard hit up google. While you're there, google the number of miles of train track in the US. That will give a rough idea of the infrastructure mileage needed just for freight.
Trucks, even with trains weaseling in on the long haul side of the trucking industry in the last couple years the amount of freight moved by trucks is staggering.
Example:http://corporate.walmart.com/our-sto...ores/logistics
158 distribution centers in the US-each one supports 90-100 stores in a 200 mile radius-the one in northern Florida has 400+ doors to load and unload.
7000 drivers averaging 100,000 miles a year. 700 million miles.....just for their fleet. The majority of these miles are distribution center to store, other trucking companies bring most of the goods into the centers.
Another truck issue is the 9 to 5 day-cab drivers (no sleeper box behind the driver). These drivers don't run a log book since they only run in a 150 mile radius from "work". If you can design an unobtrusive hyperloop like system to cover what these drivers do locally you win the world.
Long story short, the amount of freight moved is directly tied to the size of the population so the quickest way to have less trucks and trains is to tell everyone you meet to stop fucking.
