No shortage of Intermodal Shipping containers. What there IS a shortage of is the Manufacture of the items that GO INTO the containers and the Off loading of containers at the various USA ports. Most Intermodal Shipping containers are Rail freighted from the USA ports. Very few are trucked and there is a shortage of Longshoreman facilities to get the few containers off loaded and there is a shortage of Trains and crews to rail transport across the country. Once they get to the Various Intermodal rail yards in the USA, they are then trucked to final destination. Doug
