Note: There are some stranger concepts of locations in which represent in between locations in which inventory is on a truck going from place to place. I call that location as "In Transit". This location is usually used in inventory control. Inventory can't be removed from a company inventory when your redistributing the inventory to other locations. Inventory that is in transit still needs to be accounted for as inventory and be given a location of In Transit.
Please see (Baseline Conceptual Models Commentary) for further details on what conceptual models are to be used for.
