In today’s fast-paced, global logistics environment, businesses are constantly searching for smarter, more efficient ways to move goods across vast distances. With rising pressure to cut costs, lower emissions, and meet tight delivery schedules, transportation strategies are evolving quickly. One approach gaining significant traction is intermodal transportation.
According to Statistics Canada, Canadian railways moved 34.0 million tonnes of intermodal freight in 2023, reflecting the importance of containerized, multi-modal logistics in supporting national and international trade. In this guide, we’ll explore how intermodal transportation works, the key components that make it successful, real-world applications across industries, and actionable strategies to help you implement it effectively within your supply chain.
What is Intermodal Transportation?
Intermodal transportation is a method of moving goods using two or more distinct transport modes such as rail, road, sea, or air, without handling the cargo itself during the transitions. The cargo remains in a single standardized container throughout the journey, allowing for greater efficiency, enhanced security, and more reliable transit times. This approach combines the strengths of each transport method, using trucks for flexibility, trains for long-distance movement, and ships for international trade.
Multimodal vs Intermodal Transportation
While both intermodal and multimodal transportation involve moving goods across two or more modes of transportation, the difference lies in how the shipment is organized and who manages it:
- Intermodal transport uses separate contracts for each leg of the journey. The cargo remains in the same container as it moves between modes, but different carriers may handle different segments. This gives shippers more flexibility in choosing service providers and shipping routes.
- Multimodal transport operates under a single contract with one logistics provider responsible for the entire journey, regardless of how many modes are involved. This simplifies coordination but limits control over individual segments.
In short, intermodal prioritizes flexibility and carrier specialization, while multimodal offers simplicity and unified management.

How Intermodal Freight Transportation Works
The intermodal logistics chain is built on seamless coordination between transport modes, from initial pickup to final delivery. The process involves standardized intermodal containers, multiple modal transfer points, and strategic integration of digital tools, infrastructure, and service providers. Each step, from drayage to rail transport to final delivery, plays a crucial role in maintaining speed, safety, and efficiency across domestic and international supply chains.
First-Mile and Last-Mile: Road Transport and Drayage
Every intermodal shipment begins and ends with road transport. During the first-mile, trucks pick up loaded containers from the shipper’s location and transport them to a nearby intermodal terminal or port. This is commonly known as drayage.
In the last-mile, trucks handle delivery from the final terminal to the consignee. This segment offers high flexibility, especially for time-sensitive or regionally distributed deliveries. Proper handling of pallets and container loading ensures cargo security throughout. Often, freight brokerage partners assist in managing capacity and scheduling, particularly in dense or remote delivery zones.
Intermodal Terminals and Transshipment Points
Intermodal terminals play a critical role in connecting various transport modes within the intermodal freight system. These facilities are designed to transfer ISO containers between trucks, railroads, ships, and barges without unloading the contents, maintaining cargo integrity throughout the journey.
Equipped with advanced machinery such as cranes, gantries, straddle carriers, and reach stackers, terminal operators handle containers with speed and precision. Each transshipment is carefully synchronized with carrier schedules and customs procedures, especially for cross-border shipments. Well-managed terminals reduce delays, increase cargo throughput, and support the efficiency and sustainability of modern logistics networks.
Long-Haul Segment: Rail, Sea, Inland Waterways, and Air
The long-haul segment is where the main efficiency gains in intermodal shipping are realized. Depending on the destination, freight may be moved via rail transport, ocean freight, or, in some cases, air freight.
- Rail is the backbone of many intermodal systems, offering high capacity, cost-efficiency, and lower emissions for cross-country shipments.
- Ocean and inland waterway intermodal services are essential for international and regional container flows, especially through large ports and inland hubs.
- Air transport is used for high-value or urgent cargo, typically as part of a premium intermodal solution.
Strategic use of these transport modes helps balance transit times, cost, and environmental impact, which are all critical considerations in modern supply chain management.
Coordination, Scheduling, and Tracking
Behind the physical movement of containers is a digital layer that makes intermodal freight transport possible at scale. Tools like Transportation Management Systems (TMS) and Electronic Data Interchange (EDI) connect logistics providers, carriers, and terminals in real time.
These systems enable accurate container tracking, optimized modal transitions, and proactive schedule adjustments. They also manage essential documentation like bills of lading, customs clearance, and compliance forms. Together, these technologies increase visibility, reduce manual errors, and ensure that each part of the journey supports both performance and sustainability goals.
