vessel, truck, or train and transferred as needed to any mode during the journey and opened
only when it reaches its destination.
Specific vehicles are used to transport containers. At sea, containers are transported in
especially designed container ships; trains load containers in “well cars” that can fit one or two
containers in a single stack or up to four containers in a double-stack configuration. Trucks use
flat-bed trailers with special attachment points to hold the containers in place.
