Yard Time
Most facilities can tell you how long loading took. Many can tell you dwell from check-in. Very few can tell you what happened between the gate and the door. For a workforce-operations comparison point, the full guide.
That gap is where the disputed hour usually is, and it is invisible in most systems by construction rather than by neglect. For additional freight-operations context, see Progressive Railroading.
Why it disappears
The yard system starts at check-in. A driver is entered into the system when they reach the desk, and the desk is reached when there is room to reach it. Everything before is outside the record.
The carrier's system starts at a geofence. Which fires on entering a radius somebody drew, possibly including the street outside.
Neither records the segments between. Queue on the street, gate processing, waiting for a door assignment, moving to the door, waiting at the door with the engine off.
So the facility's number and the carrier's number describe different, partly overlapping intervals, and the difference is yard time. This is the four-readings problem in its most concrete form.
The four segments worth separating
If you measure nothing else, separate these.
Street to gate. Queueing outside. The segment that vanishes entirely when a facility introduces appointments and pushes the queue outward — and the classic false improvement.
Gate to check-in. Processing. Usually short, occasionally not, and easy to fix when visible.
Check-in to door. Waiting for an assignment. The largest of the four at most facilities and the one people assume is small.
Door to load start. Positioning, dock plate, waiting for a lumper or a forklift. Frequently mistaken for loading time, which makes loading look slower than it is.
The point of separating them is that they have different owners and different fixes. Aggregated into one dwell figure they are unactionable; separated, three of the four usually have an obvious cause.
How to measure it without buying anything
Gate-in timestamps. A camera, a log sheet, a guard with a clipboard. Any consistent record.
Check-in timestamps. Most yard systems already have this and nobody compares it to anything.
Door assignment time, which is a field in most systems or a note on a sheet.
And load start, which the dock knows.
Four times, four segments. A week of this on paper tells you more about your facility than a year of dwell averages, and it is the single cheapest diagnostic in this whole subject.
What it usually reveals
Patterns that recur across operations.
A morning spike. Everybody arrives before their appointment because they were burned once, and the queue at 07:00 sets the tone for the day.
One door that runs slow. Which drags the average and is invisible until you split by door.
A shift-change hole. Twenty minutes twice a day where nothing is assigned.
And a small number of loads accounting for most of the total. Averages hide this completely — a facility with a two-hour average may have most loads at forty minutes and a handful at six hours, which is a different problem needing a different fix.
Why it matters commercially
Because it is the segment you are being billed for. Loading time is rarely disputed. The disputed hour is almost always in the yard, and if you cannot describe it you are negotiating from someone else's record.
And because carriers already know. They price chronic facilities higher or decline their loads, quietly, and the facility experiences this as market tightness rather than as feedback. The cost arrives without ever appearing on an invoice.
The uncomfortable version for facilities
If your yard time is long, the invoices are the messenger. Disputing them is cheaper than fixing the yard in the short run and more expensive over a year, because the pricing effect compounds and is never itemised.
Measure the four segments before disputing the next charge. It is a week of clipboard work and it usually settles the internal argument about whether the carriers have a point.
The short version
- The gap between gate and door is invisible in most systems, and it is where the disputed hour sits
- Yard systems start at check-in; carrier systems start at a geofence; neither records the segments between
- Separate four: street to gate, gate to check-in, check-in to door, door to load start
- They have different owners and different fixes, and aggregated into one dwell figure they are unactionable
- A week of four timestamps on paper beats a year of dwell averages
- Loading time is rarely disputed; the contested hour is almost always in the yard
