Intermodal shipping refers to transporting goods using different modes of transportation, such as ships, trains, and trucks. It involves using standardized containers, also called ISO containers, to quickly transfer cargo between different modes of transport without unpacking and repacking.
People transported goods on horse-drawn wagons in the 18th century and transferred them to boats for further transportation, marking the long history of intermodal transportation. In the 19th century, the development of railroads led to the creation of containerized shipping, which allowed for more efficient and standardized transport of goods.
The concept of intermodal transportation as we know it today, involving the seamless transfer of goods between different modes of transportation, emerged in the mid-20th century with the development of containerization and the rise of trucking as a significant mode of transportation.
Today, intermodal transportation plays a critical role in global trade and commerce, with technology and automation helping further improve the system’s efficiency and reliability.
Intermodal transportation offers numerous benefits for core transportation concerns, including the following.
The combination of rail and truckload operations offers advantages in pricing and efficiency. Rail can handle long hauls, while trucks make shorter moves, resulting in increased flexibility, improved service, and reduced costs. As the amount of drayage decreases, intermodal rates become more competitive with truck rates.
Intermodal provides fast truckload solutions with streamlined operations. Drayage usually involves less than 100 miles, allowing drivers to make multiple trips to the intermodal ramp and have more turnaround time. It’s more efficient than truckload, where drivers may need to travel 2,000 to 3,000 miles before receiving a new load.
Intermodal freight transportation provides enhanced visibility, despite perceptions that visibility decreases after a container is loaded onto a train. During the loading process, all containers undergo inspection and are subsequently loaded onto railcars. Tracking is performed throughout the intermodal ramps from origin to destination and must be re-evaluated during the outgate process.
Intermodal transportation is a reliable way to transport freight safely while minimizing handling. It can lead to fewer damages and losses and increased security at terminals, rail tracks, and ramps.
Shippers should know some disadvantages to intermodal transportation, such as the following.
Intermodal transportation may require more planning from shippers due to slower transit times compared to typical truckload shipping. Additionally, intermodal shipments usually include a day of truck transport. If a consignment involves two railroads, shippers should anticipate an additional two or three days of shipment time.
The blocking and bracing requirements for shipments can be challenging and time-consuming, and the cost may outweigh the potential savings. Moreover, intermodal containers may encounter harmonic vibrations that can cause the contents to shift horizontally and vertically during transport.
Knowing any restrictions or prohibitions on certain goods is essential when utilizing intermodal transportation. If a shipper is transporting prohibited products, it’s important to note that rail transportation is not exempt from compliance with regulations and cargo liability coverage. As a result, a signed agreement between the shipper and the railroad is necessary to ensure compliance with requirements.
Contractual pricing for intermodal transportation requires a minimum volume of three loads per week on the freight lane, which may pose challenges for smaller shipments. A possible work-around to overcome this is to consider cargo consolidation.
Multimodal transportation involves a single contract that holds one carrier accountable for the entire journey, including door-to-door delivery, even if multiple carriers are utilized. On the other hand, in intermodal transportation, each leg of the journey has a separate contract, resulting in various entities responsible for the cargo’s successful delivery.
Transloading and intermodal shipping are two distinct methods of transporting goods. Transloading involves the transfer of products between different modes of transportation, whereas intermodal shipping involves transferring entire shipping containers.
There are two types of intermodal transport: international and domestic. Below are brief descriptions of both.
International intermodal transport begins with the shipment of goods from the origin point to a port. Ships load the goods at ports and transport them across the ocean to the destination countries. Upon arrival at the destination port, the containers are loaded onto a train or truck and transported to the final destination.
The transport and logistics begin with a company or individual booking their shipment with an intermodal provider. The provider will then arrange for the shipment to be picked up by a truck and transported to a rail yard. The cargo will be loaded onto a train and transported to the destination city’s rail yard. When the shipment arrives at the destination rail yard, the truck will transfer it to its destination.
One of the primary groups that should consider using intermodal transportation is businesses that transport large quantities of goods over long distances. It includes industries such as manufacturing, retail, and agriculture. Intermodal transport can help these businesses reduce transportation costs.
Another group that can benefit from intermodal transportation is businesses that need to transport goods internationally. Intermodal transportation can help these businesses navigate the complex logistics of international shipping, reducing costs and improving delivery times.
Finally, businesses looking to reduce their carbon footprint and improve their environmental sustainability should consider intermodal transportation. This mode of transportation is much more environmentally friendly than traditional shipping methods because it reduces truck traffic and uses more fuel-efficient forms of transportation.
Below are some of the most common products that can be shipped using intermodal:
Eliminate manual tasks and streamline your operations.
The four standard methods of intermodal transport vary significantly depending on the countries that utilize this form of cargo transportation.
Rail transport involves transporting packages in containers on existing railroad tracks to move cargo between destinations. It’s commonly utilized for efficient transportation between distant ports and moving freight from one hub to another, where cranes can transfer the loads to truck-based carriers.
Shipping goods via ships is the most adaptable approach among intermodal transportation methods. Ships can transport cargo across various bodies of water, allowing domestic and international trade between major ports.
The development of aircraft as an intermodal transportation method is rapid, but it still has limitations in terms of container fitting.
Trucking is one of the intermodal transportation sectors and is considered the easiest to comprehend. However, it’s also the most prone to inefficiencies. Trucks can transport all sizes of containers but can only carry one container at a time. Their primary purpose is transporting packages and goods overland on highways, roads, and streets.
Managing intermodal transportation can be complex, but SafetyCulture (formerly iAuditor) can help simplify the process. The robust platform streamlines processes tracks progress, and ensures transport and logistics operations accuracy for logistics managers, businesses, and fleet managers. Moreover, they can utilize the following checklists to address issues proactively and ensure the process runs smoothly.
