Understanding intermodal freight

Intermodal freight involves the transport of freight in a single unit using two or more forms of transportation.

Intermodal freight utilizes a combination of two or more transportation modes such as road, rail, air, or sea. In this form of shipping, the goods are sealed in cargo transport units (CTUs) whose dimensions are standardized to allow the goods to remain in the same unit across multiple modes of transportation.

This means that when a CTU is moved from one form of transport to another, it is the CTU itself that is handled and not the goods that are contained within. However, as we will explain later, there are some exceptions to this rule. Transfers occur in an intermodal station or terminal which contains specialized equipment.

It’s also worth noting the difference between the intermodal form of transportation and two related concepts in transloading and multimodal freight:

In general, intermodal transportation does not involve the handling of goods until they arrive at a final destination. During transloading, however, goods are routinely consolidated or reconsolidated as required.
In intermodal transportation, there are multiple contracts for each separate carrier. Conversely, multimodal transportation is characterized by a single contract where the same carrier is responsible for moving goods across different transportation modes.

According to research conducted by Technavio, the intermodal freight transportation market is expected to grow by $46.55 billion in the four years to 2025.

Key Concepts

Modal Integration: Intermodal freight transportation integrates multiple transportation modes, such as:
- Rail
- Truck (Road)
- Ship (Maritime)
- Air
Containerization: Intermodal freight relies heavily on containerization, where goods are packed and transported in standardized containers or trailers that can be easily transferred between different modes of transportation without the need for unpacking or repacking. Standard container sizes, such as 20-foot and 40-foot containers, facilitate seamless intermodal transfers and handling.
Hub-and-Spoke Networks: Intermodal freight networks often operate on hub-and-spoke models, where major transportation hubs serve as central nodes for cargo consolidation, transfer, and distribution. Spokes connect these hubs to various origin and destination points, facilitating efficient routing, scheduling, and coordination of freight movements.

The two categories of intermodal freight

There are two categories of intermodal freight:

International intermodal – these shipments travel in 20 or 40-foot containers between bulk carriers, trains, and trucks. Note that the products stay in the container for the entirety of the process.
Domestic intermodal – these are shipments that arrive at a port in the same 20 or 40-foot containers which are then transferred into 53-foot domestic containers. This occurs at a transload facility, cross-dock facility, or distribution center. From there, the goods travel inland to a “domestic” location.

Advantages of intermodal freight

The standardization of shipping container dimensions has clear benefits for companies and the industry as a whole:

Rapid service – containers result in the more efficient transfer of goods from one transport mode to another. Delivery times are reduced since the shipping company needs to spend less time loading and unloading.
Lower and more predictable costs – with less time spent on handling, costs tend to be lower. Many shipping companies also utilize rail transport for the longest distances to further reduce costs, with railroads in the United States able to move one tonne of freight more than 470 miles on a single gallon of fuel. Rail transport also tends to make costs more predictable as there are fewer unforeseen delays when compared to transporting goods by road.
Safety and security – intermodal rail freight tends to be a safer option for transporting flammable or hazardous materials because there is less chance of an accident. This also contributes to faster delivery as there are fewer restrictions that dictate how these materials can be transported. Intermodal freight is also inherently more secure than some other types. Since there is no requirement to handle individual items, there is less chance for opportunistic theft. What’s more, containers that are loaded onto railway cars are dropped into a well which makes them impossible to open.

Challenges in Intermodal Freight

Despite its benefits, intermodal freight transportation poses certain challenges and considerations for businesses:

Infrastructure Constraints: Intermodal freight operations require adequate infrastructure, such as rail terminals, ports, intermodal yards, and distribution centers, to facilitate efficient cargo handling, transfer, and storage, which may be lacking or insufficient in certain regions or transportation corridors.
Equipment Compatibility: Ensuring compatibility and standardization of equipment, such as containers, chassis, and intermodal railcars, across different transportation modes and carriers is essential for seamless intermodal transfers and operations, but variations in equipment specifications, sizes, and configurations can pose challenges.
Regulatory Compliance: Intermodal freight transportation is subject to various regulations, customs procedures, and safety standards imposed by transportation authorities, customs agencies, or international trade regulations, which may vary across jurisdictions and transportation modes, adding complexity and compliance challenges.

Strategies for Effective Intermodal Freight

To overcome challenges and maximize the benefits of intermodal freight transportation, businesses can adopt several strategies:

Infrastructure Investment: Invest in upgrading and expanding intermodal infrastructure, such as rail terminals, ports, and intermodal yards, to enhance capacity, efficiency, and reliability in freight transportation operations, facilitating seamless intermodal transfers and connectivity.
Equipment Standardization: Standardize equipment specifications, sizes, and configurations, such as containers, chassis, and railcars, across different transportation modes and carriers to ensure compatibility and interoperability, enabling seamless intermodal transfers and operations.
Technology Integration: Leverage advanced technology solutions, such as real-time tracking and visibility systems, predictive analytics, and interoperable platforms, to optimize routing, scheduling, and coordination of intermodal freight movements, improving operational transparency, efficiency, and decision-making capabilities.
Collaborative Partnerships: Collaborate with transportation providers, logistics partners, and terminal operators to streamline intermodal freight operations, leverage shared resources, and access specialized expertise or services to enhance efficiency, reliability, and cost-effectiveness in freight transportation.
Risk Management: Implement robust risk management protocols and contingency plans to mitigate risks such as equipment failures, capacity constraints, or disruptions in intermodal freight operations, ensuring business continuity and resilience in the face of unforeseen challenges or disruptions.

Real-World Examples

Intermodal freight transportation is widely used across industries and regions:

North American Railroads: Class I railroads in North America, such as Union Pacific, BNSF Railway, and Norfolk Southern, operate extensive intermodal networks, connecting major manufacturing hubs, ports, and distribution centers across the continent, facilitating seamless freight movement between coasts and inland destinations.
European Freight Corridors: The European Union’s Trans-European Transport Networks (TEN-T) initiative aims to develop and modernize key freight corridors, such as the Rhine-Alpine corridor and the North Sea-Baltic corridor, to improve intermodal connectivity, efficiency, and sustainability in freight transportation across Europe.
Asia-Pacific Trade Routes: Asia-Pacific countries, including China, Japan, and South Korea, rely heavily on intermodal freight transportation to facilitate trade and commerce along major maritime trade routes, such as the Asia-Europe trade lane and the Trans-Pacific trade route, connecting manufacturing centers with consumer markets worldwide.
