At the hub, packages are unloaded and sorted according to the geographical location where they are bound to. There is a hierarchy of hubs ranging from local (truck deliveries) to national (truck, rail or air) and global (air transportation). Consequently, all the parcels are divided to be loaded in the courier leading to the specified destination. If the parcel is bound locally, then it will remain at the local hub to be sorted. If the parcel is bound to a destination further than the reach of a local hub, it will then sent to another hub that will either consolidate the loads into truck, rail or air depending on the destination
