Linehaul: How Hub-to-Hub Transport Works, Where Delays Occur

TL;DR

• Linehaul is the scheduled, bulk run of freight between hubs, after first-mile pickup and before last-mile delivery.
• Each run has five stages: sort, load before cut-off, drive, unload, then return the empty vehicle.
• Road, rail, air and sea can all carry the load, and operators pick the mode lane by lane.
• Long-haul trucking is defined by distance; the hub-to-hub leg is defined by a fixed timetable.
• Most delays start at hubs and docks, and a transport management system helps planners catch them early.
• “Arrived at linehaul office” means a parcel reached a long-distance hub. It doesn’t confirm the country, customs or carrier.

Linehaul is the scheduled movement of consolidated freight between hubs, terminals or distribution centres. It sits between first-mile pickup and local delivery, and it usually runs overnight on a fixed timetable. Freight is sorted at one hub, driven overnight, then broken down again at the next hub for delivery.

In Australia, road freight reached about 253 billion tonne kilometres in 2024-25, according to BITRE. Lanes are long, so one missed departure can cost a full day. Add driver hour limits and dock queues, and a late truck at one hub becomes late deliveries across the region.

This guide explains what linehaul is and how hub-to-hub transportation works. It shows where the leg fits in the supply chain and where delays occur. It also decodes the “arrived at linehaul office” tracking status. Finally, it shows how a transport management system helps planners spot trouble early.

What Does Linehaul Mean in Australian Freight?

Linehaul is the long trip a truck makes between two hubs, carrying a big load of parcels or pallets, usually overnight. Many operators call it the middle mile because it sits in the middle of the delivery journey. You’ll also see it written as line haul freight or linehaul transportation.

Still wondering what is linehaul? Say you order a jacket from a seller in Brisbane. The courier takes your parcel to its Brisbane hub and sorts it with hundreds of others heading to Sydney.

That evening they all go onto one trailer, which drives through the night. In the morning the Sydney hub unloads it, and a local van brings the jacket to your door. The overnight drive between the two hubs is the linehaul.

Why does linehaul matter?

A truck costs almost the same to run whether it’s full or half empty. So the more parcels on board, the less each one costs, just like your jacket sharing the ride with hundreds of others. Fuel makes it matter even more. Brown & Hurley, a Queensland truck dealer, puts diesel at 30 to 40 percent of costs for linehaul fleets.

How Does Hub-to-Hub Transportation Work?

Linehaul transport runs on a timetable, often every night or several times a day, like a bus route for freight. Each run has five stages, and one early slip, like a late sort, follows the freight to the destination hub.

Consolidation at the Origin Hub

Parcels, pallets and containers arrive from the first-mile collection. Staff sort them by destination hub and group freight bound for the same place. That grouping is what makes a full trip possible. Sorting errors cost real time. A mis-sorted item rides the wrong lane and needs an extra leg to fix.

Cut-Off and Load-Out

Every outbound trip has a cut-off, the last moment freight can be accepted and still leave on time. Vehicles load inside a fixed window, usually at night. Freight that misses the cut-off waits for the next departure, which can be hours or even a full day away.

The Long-Distance Run

Trucks, trailers, rail wagons or aircraft carry the consolidated load to the destination hub. Australian lanes vary enormously. Sydney to Melbourne is roughly 880 km by road, while Sydney to Perth is close to 3,900 km. On the longer lanes, driver work and rest limits shape the plan as much as distance does.

Arrival and De-Consolidation

At the destination hub the vehicle is unloaded, scanned in and sorted by delivery route. This is the handover to local delivery vans. A late arrival squeezes the sort window, so the hub has less time to build routes before the vans leave.

Empty Return and Backhaul

After unloading, the truck or trailer heads back to its origin, ideally carrying freight the other way. That return load is the backhaul, and it often decides whether a lane makes money. A trip that runs full one way and empty the other still pays for driver and fuel in both directions.

How Does Linehaul Work in the Supply Chain?

This leg links the three physical stages of a delivery network. First-mile pickup collects freight from shippers. The hub-to-hub leg moves it across the network. Then last-mile delivery takes it to the customer. Each stage has its own cost profile and its own kind of delay.

Most parcel and LTL networks run on a hub-and-spoke design. Local depots feed regional hubs, regional hubs feed each other, and the trunk runs carry the traffic between them. Consolidating at hubs lets one network serve thousands of origin and destination pairs without a dedicated truck for each.

The pattern shifts with the type of network.

For a 3PL, the run often sits inside a customer contract. Pallets or parcels move between the 3PL’s own sites for retailers and manufacturers. That turns cut-off discipline into a service-level issue, not just an operational one. The same pressure applies to post and parcel carriers, only at a larger scale.

What Are the Key Characteristics of Linehaul?

Linehaul has six traits, whether it runs by road, rail, air or sea. The points below cover its fixed timetable, shared loads, strict cut-offs, hub-to-hub route, choice of transport and cost pressure. Together they explain why some lanes run smoothly and others don’t.

• Fixed lanes and timetables: Runs repeat between the same hubs, so planners know the capacity and arrival times in advance
• Consolidated bulk loads: Freight from many shippers travels together, which spreads the cost across all consignments
• Cut-off discipline: Every departure has a deadline, and missing it means waiting for the next run
• Hub-to-hub focus: The vehicle never visits the final customer, and sorting happens at both ends
• Mode flexibility: Road, rail, air or sea can serve a lane, depending on cost and urgency
• Cost sensitivity: Fuel, driver time and how full the vehicle is drive the cost of every trip

What Are the Core Transport Modes?

Linehaul can run on four modes: road, rail, air and sea. Road covers most first and last legs, but the run between hubs can use any of them. The table below shows where each one fits and what holds it back.

Road vehicle type matters. According to ABS definitions, a B-double is a prime mover towing two semitrailers. A road train hauls two or more trailers linked by dollies. Both carry more per trip, which suits the long intercity lanes.

At national level, BITRE estimates rail carried about 447 billion tonne kilometres in 2024-25 and road about 253 billion. Rail’s total is driven by bulk flows. BITRE’s freight map shows iron ore and coal by rail as the biggest. Air is tiny by comparison, with BITRE projecting under one billion tonne kilometres.

Linehaul vs. Long-Haul Trucking: What’s the Difference?

People often use these two terms for the same thing, but they aren’t quite the same. Linehaul is a job inside a delivery network: moving freight between hubs on a fixed timetable. Long-haul trucking is a type of trip: a truck driving a long distance, often interstate, sometimes for days. The table below shows how they differ.

The driver and load details in this table follow US trucking definitions, such as those from OTR Solutions.

In the US, linehaul usually means shorter regional runs, under about 250 to 300 miles. Australia is different. A lane between two hubs can cross state lines and take several driver shifts, so the two terms overlap more here.

An overnight run between two sort centres on a fixed timetable is linehaul, even if it’s a long trip. A one-off full truckload from a Perth manufacturer to a Brisbane customer is long-haul trucking, but not linehaul.

How Do Hub Scheduling and Shipment Consolidation Work?

A hub network runs smoothly when two things go right: each trip leaves nearly full, and the hub timetable holds. Planners balance both every day. Below, we look at how each one works and what happens when it slips.

Shipment Consolidation and Load Factor

Consolidation is the biggest lever on line haul freight cost. The fuller the vehicle, the less each shipment pays toward the trip. The catch is timing. Holding a trip to fill it risks missing the next hub’s cut-off, while sending it half-empty wastes capacity.

Two half-full trips to the same hub can merge into one if the service promise still holds. Most operators track load factor lane by lane. Lanes that run well under capacity are the first to lose money, so they’re the first to review.

Hub Scheduling and Cut-Off Windows

Hub scheduling is the timetable that sets when freight arrives, gets sorted and leaves. Inbound arrivals feed sorting, and sorting feeds outbound trips. A slip at any point squeezes the next one. If several trucks arrive together, sorting runs late and the outbound cut-off comes under pressure.

The fixes are mostly practical. Stagger arrivals, give each dock a time slot, and set cut-offs from measured sort times instead of targets. Cross-docking moves freight straight from an inbound vehicle to an outbound one, which can cut dwell time further. Software for middle-mile hub operations can handle dock scheduling and cross-dock workflows.

Where Do Delays Occur in the Linehaul Network?

Most linehaul delays don’t start on the highway. They start at the hub, where freight, trucks and drivers sit waiting. Below are seven points where time is usually lost, along with what to watch for at each one.

Missed Hub Cut-Offs

A missed cut-off sends freight to the next departure, and the gap can be hours or a full day. One late sort can wipe out the economics of a shipment, even when every other leg runs well.

The damage spreads too. Delivery routes are built around expected arrivals, so a missed departure upsets the next day’s routes as well.

Dock Queues and Slow Load-Out

Time spent waiting at the dock is time a vehicle isn’t moving. Research from the Australasian College of Road Safety links queuing at customer premises to fatigue risk for long-distance drivers. Long waits make it harder to keep drivers within legal hours and still reach the next hub on time.

Driver Work and Rest Limits

Under standard hours, NHVR rules allow a solo driver 12 hours of work in any 24. They also require 7 continuous hours of stationary rest. Two-up crews with an approved sleeper berth work to a different rest rule.

On long lanes this changes the plan. No single driver can cover Sydney to Perth, close to 3,900 km by road, inside a 12-hour work limit. That lane needs relays, two-up crews or planned rest stops. A late departure shrinks the hours left for the trip.

Part-Loaded Trips and Empty Returns

A half-full trip still pays for the same driver, fuel and vehicle as a full one. An empty return leg adds cost again when backhaul volume is low. Part-loaded trips also carry a delay risk. Teams that hold a trip to fill it may leave late, while teams that send it early waste capacity.

Late Arrivals and Weak Visibility

The destination hub builds its sort and delivery waves around expected arrival times. A late truck compresses that work, and without live ETAs the hub can’t reassign staff or docks in time. Delivery vans then leave late. Road closures and severe weather add to the problem, which is why visibility matters as much as planning.

Manual Planning

Many teams still plan hub-to-hub trips by spreadsheet and phone call. That works until volume shifts. Spreadsheet plans go stale quickly, so trips leave under-loaded or over-committed. It’s also hard to spot a problem until a truck is already late.

Peak Season Capacity Squeezes

Volume spikes strain every stage at once. Australia Post publishes Christmas cut-off dates and lists a peak fee for business customers. That shows how hard seasonal volume leans on a network. Hubs that plan for average days run short of vehicles, dock slots and sorters when volume jumps.

The table below shows what to measure at each point.

What Does the ‘Arrived at Linehaul Office’ Tracking Status Mean?

If you’ve ordered from an overseas marketplace, you may have seen “arrived at linehaul office” on your tracking page. It’s common on AliExpress orders and means your parcel was scanned in at a hub in the long-distance transport network.

It doesn’t tell you the country, the city, or whether the parcel has cleared customs. It also doesn’t say which local courier will deliver it. The next update to look for is “handed over from linehaul office”. There’s no fixed waiting time, so don’t count the days.

For operators, clear wording helps. A status that says only “arrived at hub” leaves customers guessing. Showing the location, the next step and a new ETA cuts “where is my parcel” calls, and reliable shipment tracking makes that possible.

How Does a Transport Management System Reduce Hub-to-Hub Delays?

A transport management system plans, runs and tracks freight movement in one place. For a hub network, it does four jobs, listed below: planning trips, choosing vehicles and carriers, tracking each run live, and flagging problems early.

• Trip planning: Assigns shipments to trips by deadline, fill rate and vehicle fit, then re-plans as volume builds
• Vehicle and carrier allocation: Matches each lane to own-fleet, contracted or spot capacity based on cost and on-time record
• Live execution and ETAs: Follows each run so hubs can see slippage while there’s still time to act
• Exception handling: Flags late departures, low-fill trips and routing errors before they reach the destination hub

Through multi-carrier management, a network can split lanes across own-fleet, dedicated and spot carriers by cost and performance. That matters most on busy lanes where one carrier can’t absorb a volume spike.

Shipsy’s TMS for Australian operators plans around driver hours, load limits and delivery windows, according to the company. It was named a Niche Player in the 2026 Gartner Magic Quadrant for TMS and has an office in Sydney.

What Should You Look for in a TMS for Linehaul?

A TMS only helps if it handles the delay problems covered above. Before you pick a vendor, check these five things, and ask to see each one working on your own lane data.

• Driver-hours-aware planning: Plans should reflect driver work and rest limits, with relays or rest stops built into long lanes
• Dynamic consolidation: Trips should merge, split or be added as volume builds, not just once a day
• Live tracking and ETAs: Planners and receiving hubs need to see delays early enough to act
• Carrier performance scoring: Lanes should go to carriers with a good on-time record, not just the usual ones
• Integration: Confirm it connects to your ERP, WMS and carrier systems before you sign

Conclusion

Linehaul is the part of delivery that customers never see, but it sets the pace for everything that follows. When trucks leave on time and run full, parcels reach the next hub as planned and local deliveries go out on schedule. When a cut-off is missed or a driver runs out of hours, the delay follows the parcel all the way to the doorstep.

The good news is that most of these delays can be fixed. Realistic timetables, fuller trips and live tracking catch problems before they grow, and a good TMS puts all three in one place. If your hubs keep missing cut-offs, talk to Shipsy and see how it could work on your own lanes.
