Freight modes
How each transport mode physically moves goods — the equipment it needs, the documents that ride with it, what drives its cost, and when it suits a shipper.
- Air cargo operations: what happens on the ground
The terminal workflow behind an air shipment: acceptance checks, build-up onto unit load devices, weight and balance, offloads and import break-down.
- Air charter: hiring the aircraft rather than the space
When a whole aircraft is chartered instead of buying capacity, how the aircraft is matched to the cargo, and what the lead time is really spent on.
- Air freight: paying a premium to compress time
How cargo travels on passenger and freighter aircraft, why density drives what is charged, and where the elapsed time on an air shipment really goes.
- Block trains: a whole train between two terminals
How a train that stays intact end to end avoids marshalling, what volume is needed to fill one, and why the return direction decides its viability.
- Breakbulk shipping: cargo handled piece by piece
How non-containerised general cargo is lifted, stowed and lashed aboard, what gear ship and berth must have, and when breakbulk cannot be avoided.
- Bulk shipping: cargo carried loose in the hold
How unpackaged dry and liquid cargoes are loaded and discharged, why hold condition and moisture matter, and how bulk capacity is contracted.
- Container shipping and the standard steel box
How a standardised unit turned sea carriage into an intermodal system, how boxes are identified and interchanged, and what the model handles badly.
- Courier, express and parcel: the small-consignment network
How parcel networks sort individual items at scale, why label and shape conformity govern them, and what returns traffic does to the design.
- Cross-border trucking: the frontier as an operation
What changes when a truck crosses a frontier: market-access rules, the driver's document wallet, queueing time and the constraints that follow.
- Curtainsider freight: side access under cover
How a curtain-sided body combines side loading with weather cover, when curtains count as restraint, and where it sits between van and flatbed.
- Dangerous goods freight: classified cargo under modal rules
How hazardous cargo is classified, packaged, marked and declared, and why the same substance is treated differently by sea, air, road and rail.
- Direct freight: point to point without a sorting hub
What bypassing every terminal removes from a movement, the volume conditions that justify it, and how direct trunks combine with local delivery.
- Domestic freight: movement inside one territory
How movements that never leave one territory differ in documents, network design and equipment from those that cross a customs frontier.
- Drayage: short container moves around terminals
How containers are hauled between terminals, depots and inland sites, why chassis and gate slots dominate the leg, and what triggers detention.
- Dry van freight: the enclosed general-cargo trailer
What an enclosed box trailer protects against, how rear-door loading and load restraint work inside it, and the cargo shapes it cannot take.
- Expedited freight: recovery moves under pressure
What an urgent recovery movement actually involves, how continuous running is organised, and when paying for immediacy buys nothing at all.
- Express freight and time-definite services
How integrated express networks hold a time-definite commitment, why cut-offs govern the service, and what such networks decline to carry.
- Flatbed freight: open-deck carriage of awkward loads
Why some cargo needs an open deck, how flatbed loads are lashed and sheeted, and what the absence of walls demands of the shipper.
- Full container load (FCL): one shipper, one box
How an exclusive container is packed, sealed and moved, why declared weight matters before loading, and where a whole box beats sharing one.
- Full truckload (FTL): buying the whole vehicle
Why a shipper buys an entire vehicle: how exclusive-use truckload runs point to point, what governs turnaround, and the trade against shared services.
- Groupage: consolidating part loads onto a scheduled trailer
How unrelated part loads are combined onto one scheduled international trailer, why cut-offs are enforced, and what shared exposure means for shippers.
- Heavy haul: moving indivisible loads by road
How abnormal indivisible loads are engineered onto specialist trailers, why route surveys precede everything, and what escort vehicles are actually for.
- High-value freight and security in transit
How consignments attractive to thieves are routed, specified and monitored while moving, and why parking and information discipline outweigh hardware.
- Hub-and-spoke freight networks
Why consolidating flows through a central sorting point beats running everything point to point, and what passing through a hub costs a consignment.
- Intermodal freight: one loading unit, several modes
How a single loading unit crosses road, rail and sea without the goods being touched, and the terminals and equipment that make it possible.
- International freight: what crossing a frontier adds
The mechanics that appear once goods leave a territory: extra handovers, a document per mode, longer dwell and packing built for a rougher journey.
- Last-mile freight: the final leg into the delivery point
Why the shortest leg absorbs so much of the cost, what urban access and receiver behaviour dictate, and which design choices genuinely reduce it.
- Less than container load (LCL): sharing a box
How small sea consignments are consolidated into a shared container, what the extra warehouse steps add, and when a whole box becomes better value.
- Less-than-truckload (LTL) network movement
How a part load travels through terminals and trunk vehicles, why handling shapes packaging, and where shared-network freight stops making sense.
- Milk runs: one vehicle, several suppliers, fixed route
How a single vehicle collects small quantities from several suppliers on a repeating route, what keeps the timetable intact, and where the model fails.
- Multimodal freight and the through movement
How a journey combining several modes is sequenced and documented as one carriage, and where time and responsibility concentrate at the joins.
- Ocean freight: moving goods by sea
How sea carriage works as a scheduled system, what has to happen between booking and sailing, and why elapsed time exceeds days at sea.
- Oversized cargo: loads that break the standard envelope
How out-of-gauge loads are measured and routed by each mode, why one dimension can eliminate an option, and what can be done at the design stage.
- Pallet freight and overnight pallet networks
How pallet networks trunk unit loads through an overnight hub, what makes a pallet acceptable, and which goods suit the standardised model.
- Pharmaceutical freight under validated temperature control
Why medicinal products travel in qualified packaging on mapped lanes, how excursions are assessed against stability data, and what records must show.
- Project cargo: engineered movements for one-off shipments
How single large industrial consignments are engineered from factory to foundation, why surveys and lifting studies come first, and what schedules hinge on.
- Rail freight: fixed infrastructure and long trains
How goods move by rail, what track access, loading gauge and axle load dictate, and why rail movements almost always need road at both ends.
- Reefer containers: temperature control across a sea leg
How a refrigerated container holds its setpoint for weeks at sea, what plugging and monitoring require, and the moments where the cold chain fails.
- Refrigerated freight: chilled and frozen road distribution
How temperature-controlled vehicles hold chilled and frozen loads through multi-drop rounds, and what door openings and mixed loads do to the chain.
- Road freight: how trucking moves goods over land
How trucking physically moves goods door to door, the vehicles and driver rules it depends on, and the load limits that shape every route.
- Roll-on roll-off shipping: cargo that drives aboard
How wheeled and tracked cargo is driven onto vessels, what ramps and deck heights dictate, and why turnaround speed defines the RoRo trade.
- Short sea shipping: coastal and regional maritime legs
How coastal and intra-regional sea services compete with driving, what feeder and trailer patterns look like, and what port access decides.
- Tanker shipping: liquids carried in bulk
How liquid cargoes are pumped into segregated tanks, why cleaning and heating regimes govern the trade, and what the ship-to-shore interface involves.
- Time-critical freight and hand-carry services
How consignments with an immovable deadline move by on-board courier, next-flight-out or dedicated vehicle, and what each option genuinely controls.
- Transhipment: changing ship part-way through a voyage
Why containers move between vessels at intermediate hub ports, what the connection depends on, and what a missed connection does to a shipment.
- Transloading: shifting cargo between conveyances
Why cargo is deliberately transferred out of one conveyance into another mid-journey, what the operation involves, and what the rehandling risks.
- White-glove delivery: placement, assembly and in-home handling
How two-person crews place, assemble and unpack goods inside a customer's premises, and what site survey and appointment scheduling that demands.
