Trunk runs

Nobody has seen these since the other city

Loaded onto a truck that has arrived, and never came off. Empty is the good state. The longer one of these sits unread the colder the trail, which is the whole reason a manifest has two timestamps instead of one.

The trucks

A run is one truck on one day between two hubs. It cannot leave without a crew and something on it, it cannot take anything on once it has left, and it cannot be closed while a parcel is unaccounted for — every box either came off or somebody said what happened to it.

Send a parcel to another hub

A parcel is local until somebody says otherwise — which is what every parcel this business has ever booked has been. Naming the hub it has to reach is what puts it on the waiting list for a truck. Deliberately a person's decision rather than worked out from the address: getting it wrong sends a box to the wrong city, and a coverage map is a much bigger thing than a column.

The timetable

The standing schedule — which hub to which hub, on which days, leaving when, taking about how long. A service is not a truck. The transit time is a planning figure a dispatcher uses to decide whether Thursday's truck still makes Friday's round; it is not a promise to a customer. Service tiers are what promise anybody anything.
