How intermodal transportation works is a question many shippers ask when looking to move freight efficiently across long distances. In simple terms, intermodal transportation combines two or more transportation modes — usually truck and rail — to move cargo in the same container without unloading it between transfers.
In this guide, you’ll learn exactly how intermodal transportation works, when it’s the right choice, what steps are involved, how long it takes, how much it costs, and how Canadian intermodal networks operate in practice.
What Is Intermodal Transportation?
Intermodal transportation is a freight shipping method that uses multiple modes of transport under separate contracts, most commonly:
- Truck → Rail → Truck
- Port → Rail → Truck
- Rail → Truck (domestic inland moves)
The cargo stays inside the same container or trailer throughout the entire journey. This reduces handling, minimizes damage risk, and lowers overall transportation costs on long‑haul routes.
Intermodal shipping is widely used in Canada for cross‑country moves between major logistics hubs such as Vancouver, Toronto, Montreal, Calgary, Edmonton, and Halifax.
How Does Intermodal Transportation Work? (Step‑by‑Step)
Understanding how intermodal transportation works becomes simple when you break it into clear operational stages.
Step 1 — Origin Pickup by Truck
The process starts when a truck picks up the loaded container or trailer from the shipper’s warehouse, factory, or port terminal. This is known as first‑mile drayage.
The container is sealed and transported to the nearest intermodal rail terminal operated by CN or CP Rail in Canada.
Step 2 — Transfer at the Intermodal Terminal
At the rail terminal, specialized cranes or reach stackers lift the container from the truck chassis and place it onto a rail flatcar or double‑stack railcar.
No cargo is unloaded. The container remains sealed during the entire transfer process.
This stage usually takes 2–24 hours depending on terminal congestion and rail schedules.
Step 3 — Long‑Haul Rail Transportation
The rail segment is the core of intermodal transportation.
Rail moves the container across long distances efficiently, often covering thousands of kilometers at a lower cost and with fewer emissions compared to full truckload shipping.
Common Canadian rail corridors include:
- Vancouver → Toronto
- Vancouver → Calgary / Edmonton
- Montreal → Toronto
- Halifax → Montreal / Toronto
Transit time by rail typically ranges from 3 to 7 days depending on route length and rail network conditions.
Step 4 — Destination Terminal Transfer
Once the train arrives at the destination intermodal terminal, the container is unloaded from the railcar and placed onto a truck chassis.
This stage is known as destination drayage.
Step 5 — Final Delivery by Truck
A local truck driver delivers the container to the consignee’s warehouse, distribution center, or job site.
The container is opened and unloaded only after final delivery, completing the intermodal shipping process.
Intermodal Transportation Process Flow
| Stage | Transport Mode | Typical Time |
|---|---|---|
| Origin pickup | Truck | Same day – 1 day |
| Terminal transfer | Crane handling | 2 – 24 hours |
| Long‑haul transport | Rail | 3 – 7 days |
| Destination transfer | Crane handling | 2 – 24 hours |
| Final delivery | Truck | Same day – 1 day |
Why Companies Use Intermodal Transportation
Intermodal transportation has become one of the most popular freight solutions in Canada because it offers a balance between cost, reliability, and sustainability.
Main Benefits
- Lower transportation costs on long distances
- Reduced fuel consumption compared to trucking only
- Lower carbon emissions
- Less cargo handling and lower damage risk
- Stable pricing during fuel price fluctuations
For shipments over 700–800 km, intermodal shipping is often more economical than long‑haul trucking.
Intermodal vs. Multimodal Transportation
Many shippers confuse intermodal and multimodal shipping. While both use multiple transport modes, there is a key contractual difference.
| Feature | Intermodal | Multimodal |
|---|---|---|
| Number of contracts | Multiple | Single |
| Carrier responsibility | Separate per mode | One carrier for entire route |
| Flexibility | High | Medium |
| Risk management | Shared | Centralized |
Intermodal offers more pricing flexibility, while multimodal offers simpler administration.
What Affects Intermodal Transportation Transit Time
Several operational factors influence how fast intermodal transportation works in real life:
- Rail network congestion
- Terminal dwell time
- Weather conditions
- Border crossings (for US‑Canada routes)
- Container availability
- Seasonal peak volumes
On average, intermodal transit times are 1–3 days longer than full truckload shipping but significantly cheaper on long routes.
Intermodal Transportation Costs (Typical Ranges)
While pricing varies by market conditions, here are realistic cost ranges for Canadian intermodal shipping.
| Route | Intermodal Cost (Approx.) | Truck Cost (Approx.) |
|---|---|---|
| Vancouver → Toronto | $3,000 – $4,500 | $5,000 – $6,500 |
| Vancouver → Calgary | $1,800 – $2,800 | $3,000 – $3,800 |
| Montreal → Toronto | $900 – $1,400 | $1,400 – $2,000 |
Prices are approximate and may vary depending on fuel, season, equipment availability, and terminal charges.
When Intermodal Transportation Is the Best Choice
Intermodal transportation works best when:
- Shipping over long distances
- Moving full containers or trailers
- Delivery is not extremely time‑critical
- Sustainability is a priority
- Fuel price volatility is high
Industries that frequently use intermodal shipping include:
- Manufacturing
- Retail and e‑commerce
- Automotive parts
- Construction materials
- Consumer packaged goods
Intermodal Transportation in Canada
Canada has one of the most developed intermodal rail networks in North America, operated primarily by:
- CN Rail
- CP Rail
Major intermodal hubs include:
- Vancouver (Port of Vancouver, Deltaport)
- Toronto (Brampton, Vaughan, Milton terminals)
- Montreal (South Shore terminals)
- Calgary and Edmonton
- Halifax
Intermodal transportation connects Canada’s ports with inland distribution centers and cross‑border corridors into the United States.
Operational Pitfalls & How to Optimize Intermodal Shipping
Instead of focusing on generic questions, experienced shippers benefit more from understanding the real operational risks and optimization points inside the intermodal process.
Terminal Dwell Time Management
One of the biggest hidden cost drivers in intermodal transportation is terminal dwell time. Containers left at origin or destination terminals beyond free time can quickly generate storage and demurrage charges. Working with a specialized provider of intermodal logistics helps coordinate rail cut-off times, chassis availability, and terminal appointments efficiently.

Equipment Availability & Chassis Planning
Rail capacity alone does not guarantee smooth execution. Chassis shortages and container imbalances frequently delay first-mile and last-mile delivery. Advanced intermodal operations monitor equipment pools and pre-book chassis to avoid idle time and missed rail departures.
Network Congestion & Seasonal Planning
Peak seasons at Canadian ports and rail hubs — especially in Vancouver, Toronto, and Montreal — often slow down intermodal flows. Proactive routing, flexible rail scheduling, and buffer transit days are critical to maintaining delivery reliability.
When to Use Dedicated Intermodal Logistics Providers
Complex intermodal routes benefit from centralized coordination. A dedicated intermodal logistics provider manages drayage, terminal handling, rail booking, and last-mile delivery under one operational strategy, reducing handoffs and minimizing risk across the entire corridor.
Final Thoughts
Understanding how intermodal transportation works helps shippers reduce costs, improve sustainability, and optimize long‑distance freight planning. With Canada’s strong rail infrastructure and growing intermodal capacity, this shipping method continues to be one of the most efficient logistics solutions for domestic and international supply chains.
