Initially, delivery vehicles transport the parcels from the origin warehouse to hubs located at train stations. Subsequently, the parcels are transferred using the rail network to satellites, also situated at train stations. At the satellites, the parcels are unloaded onto smaller delivery vehicles operating from the satellites. Finally, these vehicles will be used to deliver the parcels to their final destinations.
