Example of Ocean Freight in a 40' Container

Consider a shipment that begins as ocean freight in a 40-foot container. This container is loaded onto a ship at the port of origin and transported across the ocean to its destination port. Upon arrival, the 40-foot container is offloaded from the ship and placed onto a train. The train carries the container over long distances, leveraging the efficiency and cost-effectiveness of rail transportation. Once the train reaches its designated rail terminal, the container is transferred to a chassis, a specialized trailer designed to carry containers. A truck then hooks up to the chassis and delivers the container to its final destination, such as a warehouse or distribution center. This combination of ocean, rail, and truck transport showcases the seamless integration and efficiency of intermodal shipping, ensuring goods are moved quickly, safely, and cost-effectively from origin to destination.

Example of a 53' Domestic Rail Container

Another example involves a 53-foot domestic rail container. This container is loaded with goods at a manufacturing plant. It is then transported by truck to an intermodal ramp, where it is loaded onto a train. The train transports the container over a long distance to a different location. Upon arrival at the destination rail terminal, the container is offloaded onto another chassis. A truck then picks up the chassis and delivers the container to its final destination, such as a distribution center or retail facility. This process demonstrates the efficiency and versatility of intermodal shipping, using different transportation modes to optimize the movement of goods across various distances.

Intermodal Containers and Freight Handling

One of the key components of intermodal shipping is the use of standardized intermodal containers.

This streamlined process not only saves time but also reduces the risk of damage to the goods during transfer. Efficient freight handling is essential for ensuring the smooth flow of intermodal shipments.

Intermodal containers come in various sizes and types to accommodate different cargo needs. The most common sizes are 20-foot and 40-foot containers, often referred to as TEUs (Twenty-foot Equivalent Units) and FEUs (Forty-foot Equivalent Units), respectively. These containers are used globally and are ideal for a wide range of goods, from electronics to clothing.

Domestically, 48' and 53' rail containers are available for shipping goods.  These containers typically are owned by asset-based carriers, railroads or intermodal marketing companies (IMCs).

In addition to standard dry containers, there are several specialized types of intermodal containers:

High Cube Containers: These containers are similar in length and width to standard containers but offer an extra foot in height, providing more volume for cargo that is lightweight but bulky.

Refrigerated Containers (Reefers): These containers are equipped with temperature control systems, making them suitable for transporting perishable goods such as food, pharmaceuticals, and chemicals that require specific temperature conditions.

Open Top Containers: Designed for cargo that cannot be easily loaded through the container doors, open-top containers have a removable roof, allowing goods to be loaded from the top using cranes.

Flat Rack Containers: These containers have collapsible sides and are used for oversized cargo that does not fit into standard containers, such as machinery and vehicles.

Tank Containers: These containers are designed to carry liquids, gases, and powders. They are made of strong materials to ensure safe transportation of hazardous or sensitive liquids.

Insulated Containers: These are used for goods that need to be protected from extreme temperature variations but do not require refrigeration. They maintain a stable internal environment using insulation materials.

Each type of intermodal container is built to withstand the rigors of multiple transportation modes, ensuring that goods are protected and remain intact throughout their journey. The variety of container types allows for the efficient and safe transportation of a wide range of products, contributing to the overall effectiveness and reliability of intermodal shipping.
