Intermodal vs Road:
The Real Comparison

What Is Intermodal Transport?

Intermodal transport — also called combined transport or multimodal transport — uses two or more transport modes (road, rail, sea) for a single shipment. The cargo stays in the same trailer or container throughout, transferred between modes by crane or reach stacker at intermodal terminals.

In practice: a truck collects the cargo (first mile), the trailer is loaded onto a train or RoRo ferry for the long-haul leg, then another truck delivers at the destination (last mile).

For the full picture — how the chain works, the difference between intermodal, combined and multimodal, equipment and our network — see our guide to intermodal transport in Europe.

Cost Comparison

Intermodal becomes clearly competitive on routes of around 1,000 km and longer, due to:

• Significantly lower fuel consumption on rail and sea legs
• No road tolls on the main corridor
• No driver daily allowances for the long-haul leg
• 4 extra tons of payload under EU Combined Transport Directive (44t vs 40t)
• No costs related to weekend driving ban delays

Transit Time

Intermodal transit times are comparable to road on longer routes, and often more predictable due to fixed rail and ferry timetables. Unlike road transport, intermodal is not affected by:

• Weekend and nighttime driving bans
• Border crossing delays and inspections
• Traffic congestion on major corridors
• Driver availability and rest time regulations

When Is Intermodal the Right Choice?

• Routes of around 1,000 km and longer — the longer the route, the lower the cost per tonne
• Regular, high-volume flows where fixed schedules work well
• Heavy or dense cargo (metals, timber, paper, machinery) that benefits from 44t limit
• Companies that need a documented basis for Scope 3 transport emissions
• Shippers affected by road driving bans (weekend, holiday periods)

When Is Road Still Better?

• Shorter distances — road is usually the better option
• Time-critical same-day or next-day deliveries
• Unusual cargo dimensions that don't fit standard intermodal equipment
• Areas without intermodal terminal access at origin or destination

The EU Combined Transport Directive

The EU Combined Transport Directive grants a key advantage: shipments using at least one non-road leg (rail or sea) are allowed a maximum weight of 44 tonnes — 4 tonnes more than standard road transport. Cost per tonne depends on the route — the longer the route, the lower the cost per tonne. More in our guide to combined transport in Europe.
