Piggybacking refers to an intermodal transportation strategy that involves loading truck trailers or containers onto railcars to be transported from one terminal to another. This method takes advantage of the fuel efficiency and labor savings of rail transport while maintaining the point-to-point delivery capabilities of trucks.
Why Piggybacking is Efficient
Piggybacking combines the best of both worlds—rail transport and trucking. Here are some key advantages:
- Fuel Efficiency: Rail transport is significantly more fuel-efficient than road transport, especially over long distances.
- Labor Savings: Rail reduces the need for multiple truck drivers for long hauls.
- Reduced Road Congestion: By shifting freight to rail, there’s less road congestion and wear.
Types of Piggybacking
TOFC (Trailer on Flatcar)
TOFC involves loading entire truck trailers onto flat railcars. This system is especially useful for transporting double-stack trailers.
COFC (Container on Flatcar)
COFC involves loading containers that can be detached from truck trailers onto railcars. Containers can also be double-stacked on specially designed railcars for increased capacity.
Special Considerations
- Infrastructure: Requires well-developed intermodal terminals and supporting infrastructure.
- Coordination: Effective piggybacking requires coordination between rail and trucking companies to manage schedules and logistics.
- Cost: While potentially more efficient, piggybacking can involve higher initial costs for handling and infrastructure.
Historical Context
Piggybacking emerged in the mid-20th century as a response to the need for more efficient transport solutions. Initially adopted in North America, it has since spread to many parts of the world, driven by globalization and the growing need for efficient logistics.
Applicability
Piggybacking is particularly suitable for:
- Long-Distance Transport: Ideal for distances over 500 miles where rail’s fuel efficiency becomes more advantageous.
- High-Volume Routes: Effective on routes with high freight volumes due to economies of scale.
- Urban Deliveries: Reduces the need for trucks to enter congested urban areas, using rail to bring goods closer to urban centers.
Comparisons
Piggybacking vs. Traditional Trucking
- Efficiency: Piggybacking is generally more fuel-efficient for long distances.
- Flexibility: Traditional trucking offers better point-to-point flexibility.
Piggybacking vs. Air Freight
- Cost: Piggybacking is more cost-effective for bulk goods.
- Speed: Air freight is faster but significantly more expensive.
Related Terms
- Intermodal Transport: The use of more than one mode of transport to move goods from origin to destination.
- Multimodal Transport: Similar to intermodal transport but involves agreements with different carriers for each mode.
- Freight Forwarding: The logistics planning and execution of freight shipment on behalf of shippers.

Summary
Piggybacking presents a compelling alternative to traditional freight transport methods by merging the fuel efficiency of rail with the flexibility of road transport. With advancements in infrastructure and logistics, its role in global supply chains is likely to grow, offering sustainable and cost-effective solutions for various transportation needs.
