The Advantages Of
Intermodal trains are a game-changer for long-distance hauls, especially when it comes to big shipments. They're way cheaper than trucks, and a single train car can carry way more than a truck.
Trains are also super fuel-efficient, which means they pollute less and are better for the environment. Intermodal Sustainability has been a positive talk in the industry for quite some time now.
Here are some key benefits of intermodal trains:
- Cheaper for long hauls
- More fuel-efficient
- Less air pollution
- More efficient for big deliveries
- Less likely to get into accidents
- Run on schedules
Trains can also carry big containers or separate wagons full of stuff, depending on your needs. This makes them super versatile and adaptable to different types of shipments.
Disadvantages of Intermodal Train
Intermodal trains have their downsides, and it's essential to consider them before shipping your goods. Trains can't always provide the special care that fresh food needs, so it might not be the best option for perishable items.
In some areas, the quality of train tracks can be a problem, causing trains to run unevenly and potentially leading to delays or damage to your cargo. This is especially true in remote areas where tracks might not be as well-maintained.
Loading and unloading cargo from trains multiple times can be time-consuming, which might not be ideal if you're working on a tight deadline. The longer your cargo is on the move, the higher the chance of something happening to it, so make sure it's well-secured.
Here are some specific challenges you might face when shipping by intermodal train:
How Intermodal Train Works

Intermodal trains work by combining road and rail transportation. The journey typically starts with a dray truck driving the container to an intermodal ramp.
The railroad takes over from there, handling the long-haul portion of the trip. This is where the train really gets going, carrying the container across the country.
The intermodal journey concludes with another dray truck picking up the container at its destination and delivering it to its final destination.
How Train Works
Regular trains are like delivery trucks that pick up lots of different boxes going to many places. They stop at hubs, known as train yards, to unload some boxes and pick up new ones for other deliveries.
Intermodal trains, on the other hand, start at special terminals assigned by intermodal rail companies. These terminals, also known as intermodal facilities, handle cargo-filled containers and are strategically located near major seaports, highways, and border crossings.
Unit trains are a type of special train that only carries one type of good, like all TVs. They travel directly from the factory to the store without any stops to switch cargo, making them much faster.
Intermodal rail transportation involves a combination of road and rail, with a container being the key to this process. The railroad takes the container for the long-haul portion of intermodal transport, before another dray truck takes it to its destination.

Double Stacking

Double Stacking was a game-changer in the world of intermodal train transport. In 1977, Malcom McLean and Southern Pacific Railroad tested the first double-stacked intermodal railcar.
This breakthrough became widespread by 1980, revolutionizing the way freight was transported. The double-stacked trains can carry as much freight as hundreds of trucks.
Railroads upgraded their tunnels, clearances, and tracks to accommodate these massive trains, which has significantly boosted efficiency. With rail being four times more fuel-efficient than trucks, double stacking has also reduced greenhouse gas emissions.
Intermodal Train History and Success
The history of intermodal trains is a story of innovation and efficiency. Enabled by regulatory reforms in 1980, railroads invested heavily in intermodal infrastructure and technology.
In the 1950s, goods were transported loose in small packages, known as break bulk, which was a laborious and lengthy process. Standardized containers made intermodal the preferred method of international transport.
The modern intermodal industry was born with the introduction of metal shipping containers, inspired by the military's use of containers during WWII. Double-stack rail transport, introduced in 1984, offered greater efficiencies.
History of

Intermodal transportation has a fascinating history, and I'm excited to share it with you.
In the 1950s, most goods were transported loose in small packages, known as break bulk, which was a laborious and time-consuming process.
The introduction of containerized shipping in the 1950s revolutionized the industry, using metal shipping containers like those used by the military in WWII, capable of truck or train transport.
This marked the beginning of the modern intermodal industry, which soon became the preferred method of international transport.
Standardized containers were introduced, making intermodal the go-to choice for global shipping.
In 1984, double-stack rail transport was introduced, offering greater efficiencies and further solidifying intermodal's place in the industry.
The regulatory reforms of 1980 paved the way for railroads to invest heavily in intermodal infrastructure, technology, and services, making freight transport more efficient, cost-effective, and adaptable.
Today, intermodal transportation is a key player in global commerce, seamlessly integrating with trucking and maritime industries to create a more flexible and resilient supply chain.
Domestic Growth and Tech Enhancements

In 1989, a significant partnership was formed between trucking magnate Johnnie B. Hunt and Santa Fe Railway to move truck trailers on flatcars, revolutionizing domestic freight transport.
Rising fuel costs, driver shortages, and highway congestion have made rail a competitive alternative to trucking, even for short-haul shipments.
Railroads have invested heavily in zero-emission electric cranes for faster, cleaner container transfers.
Optical scanners and automated gates have been implemented to reduce truck idling and enhance security at terminals.
Intermodal Train Operations
The intermodal train process starts at the nearest intermodal ramp facility, where an empty railroad-owned container or trailer is delivered to the shipper's dock.
Domestic shipments typically begin with delivery of an empty container or trailer from a Norfolk Southern intermodal facility. This sets the stage for the efficient movement of freight.
Intermodal train operations rely on a network of terminals and schedules to ensure smooth transportation.
Types of
Intermodal train operations offer a range of options for shippers, and understanding the different types can help you make informed decisions.

There are two main types of intermodal transportation: Container-On-Flatcar (COFC) and Trailer-On-Flatcar (TOFC). COFC, which became prominent in 1984, is the most common and cost-effective method.
COFC allows for four containers to be loaded onto one wellcar, making it a highly efficient option. In contrast, TOFC places the over-the-road (OTR) trailer directly onto the wellcar, with a maximum of two trailers at a time.
Here's a breakdown of the different types of intermodal providers:
- Bi-Modal: These providers own assets like containers, chassis, and dray capacity, but the railroads own the train-related assets.
- Asset-Lite: These providers own just a few intermodal assets, often limited to dray equipment.
- Non-Asset: These providers own no intermodal assets, instead relying on the Class 1 railroads and developing relationships with dray companies.
- Rail Retailers: In Canada, railroads like Canadian National and CPKC sell direct intermodal service for north of the border loads.
- Freight Brokers: Traditional freight brokers can offer intermodal service, but only through a registered intermodal marketing company (IMC).
Process Begins at Nearest Ramp Facility
The process of intermodal train operations begins at the nearest intermodal ramp facility. This is where the journey starts for domestic shipments, which typically begin with the delivery of an empty railroad-owned container or trailer from the nearest Norfolk Southern intermodal facility to the shipper’s dock.
Domestic intermodal reliably covers all of North America, making it a convenient option for shippers. Modern intermodal transport is an environmentally friendly and cost-efficient way to move freight long distances.

Intermodal terminals date back to the 19th century and were converted into intermodal facilities by 1960 with the rise of container shipping. Modern intermodal relies on strategically located terminals where freight transfers between modes.
Here are the different types of intermodal transportation: Container-On-Flatcar (COFC)Trailer-On-Flatcar (TOFC) COFC, which came to prominence in 1984, is the most common and cost-effective method because four containers can be loaded onto one wellcar.
Transport vs. Truckload
Intermodal transport has its place in logistics and supply chains, but it's worth considering the differences between intermodal freight transportation and over-the-road truckload shipping.
Intermodal transport often wins in terms of fuel efficiency, with studies showing that intermodal trains use 30% less fuel than trucks over long distances.
For shippers, the decision between intermodal and truckload often comes down to cost and time sensitivity. Both options have their place, but intermodal transport can be a more reliable choice for high-priority shipments.
Intermodal trains can carry a large volume of cargo, with some trains capable of hauling over 2,000 containers at a time. This makes them a more efficient option for shippers with high-volume shipments.
Tracking Protocols via Lane Visibility

Tracking protocols via lane visibility offer a competitive advantage in managing freight journeys. This is similar to small parcel tracking, which allows companies to check the status of a shipment as it moves along the railway.
Companies can "keep eyes everywhere" by using this tracking protocol, giving them a more accurate view of their shipments. This is especially useful for shippers who want increased lane visibility.
Shippers who use this protocol can benefit from reduced uncertainty and improved supply chain visibility. This can lead to better decision-making and more efficient operations.
Select an IMC
Selecting the right Intermodal Marketing Company (IMC) is crucial for a successful intermodal transition. You have many options to choose from, more than you might think.
There are various types of IMCs, including Bi-Modal, Asset-Lite, Non-Asset, Rail Retailers, and Freight Brokers. Each type has its own strengths and weaknesses.
Bi-Modal IMCs own assets like containers, chassis, and dray capacity, while Asset-Lite IMCs own just a few intermodal assets. Non-Asset IMCs, on the other hand, own no intermodal assets and rely on Class 1 railroads and dray companies.

To choose the right IMC for your needs, consider the services you require and the level of control you need over your intermodal operations. Some IMCs may offer more flexibility and customization than others.
Here are some key characteristics of different types of IMCs:
Ultimately, the best IMC for you will depend on your specific needs and goals. Take the time to research and evaluate different options before making a decision.
Intermodal Train Efficiency and Capacity
Intermodal train efficiency and capacity are key benefits of this transportation method. Intermodal trains offer consistent railroad schedules with reliable service.
This reliability is due in part to the energy efficiency of trains combined with the flexibility of trucks. The constant movement of trains, sealed containers, and secured ramps also lead to a low cargo theft risk.
Intermodal trains have significant capacity availability, with some trains capable of carrying up to 280 53-foot containers. This makes them a popular choice for businesses that need to transport large quantities of goods.
A key advantage of intermodal trains is their ability to balance energy efficiency with flexibility. This balance is achieved through the combination of train and truck transportation methods.
Intermodal Train Logistics and Planning

Intermodal train logistics and planning involve coordinating multiple modes of transportation, such as trucks, ships, and trains, to move goods efficiently.
The key to successful intermodal train logistics is careful planning, which considers factors like route optimization, cargo handling, and regulatory compliance.
Intermodal terminals, like the one in Savannah, Georgia, play a crucial role in this process, offering a range of services including container storage and transfer.
Load Shipment
Loading a shipment on an intermodal train is a precise process. Containers are often loaded two high, or "double-stacked", to allow twice as many shipments to be moved on one train.
This method saves customers money, enhances transportation efficiencies, and supports conservation efforts by saving fuel and reducing emissions.
At the terminal, a hostler positions the container or trailer beside the rail car that will be used for the line haul. A crane carefully lifts the container or trailer and positions it securely on the car for departure.
Intermodal trains can move large amounts simultaneously, making it ideal for appointed loads or retail deliveries that require a high percentage of on-time deliveries.
Selecting from Diverse Providers
Intermodal logistics can be complex, but selecting the right provider doesn't have to be. There are many more intermodal providers than shippers often think, so don't assume there are only a few options.
You can choose from different types of providers, including asset IMCs, asset-lite IMCs, non-asset providers, rail retailers, and freight brokers. Each type has its own strengths and weaknesses.
Asset IMCs, like asset-lite IMCs, own some intermodal assets, but the railroads own the train-related assets. Non-asset providers, on the other hand, don't own any intermodal assets and rely on relationships with dray companies and Class 1 railroads.
Not all providers are created equal. Some, like Canadian National and CPKC, can even sell direct intermodal service to shippers.
Here's a breakdown of the different types of providers:
Selecting the right provider is crucial for a smooth intermodal journey. By understanding the different types of providers and their strengths, you can make an informed decision that meets your needs.
Intermodal Train Eligibility and Requirements

To be eligible for intermodal train service, your cargo must be in a suitable container, such as a 20-foot or 40-foot steel boxcar.
Containers must be in good condition and meet the requirements of the Association of American Railroads (AAR) to ensure safe transportation.
Some common types of cargo that qualify for intermodal train service include dry goods, perishables, and hazardous materials.
Haul Length ≥ 600 Miles
For hauls of 600 miles or more, intermodal shines with its efficiency and strength. This is where economies of scale really take hold.
Intermodal can be competitive with truckload for shipments as short as 450 miles if dray moves are near ramps.
Dray Distance for Ramps ≤ 100 Miles
Dray distance for ramps is a crucial factor in intermodal transportation. Dray distance for intermodal ramps is no more than 100 miles.
To create a good intermodal lane, a shipment should have dray lengths of 50 miles or less from the origin and destination ramps. This helps in achieving the best road-to-rail conversion.
As the linehaul segment on the rail increases, the drayage distance can also increase in either or both directions.
Shipment Weight ≤ 42,500 Lbs

Shipment weight is 42,500 lbs or less. This is a crucial consideration for intermodal transport.
Weight and weight distribution are vital for intermodal transport. Both overweight and poorly distributed loads can face compliance issues and costs.
Proper load configuration is a must to avoid these issues.
The heaviness of the chassis/container combo reduces the gross freight weight of an intermodal shipment by 2,500 lbs.
Common Misconceptions and Myths
Intermodal train transportation has several misconceptions surrounding it. One of the most common myths is that it's unreliable.
In reality, intermodal freight lanes have on-time deliveries that rival or beat truckload because of the precision of rail transit schedules. This is because railroads have easily tracked transit times allowing for consistent planning over the long-term.
Another myth is that intermodal transportation is slow. However, this is not necessarily true.
