What You'll Learn
Freight trains are more fuel-efficient than trucks
While trucks are more flexible and can carry freight on any route, freight trains are more fuel-efficient than trucks. This is especially true for long-haul routes (800 miles or more) between major cities or from ports to major cities or distribution centers.
Freight trains can carry one ton of freight nearly 500 miles while only using one gallon of diesel fuel. In comparison, a heavy-duty diesel truck hauling 19 tons of freight for 500 miles would consume approximately 71 gallons of diesel fuel. This makes freight trains 3-4 times more fuel-efficient than trucks.
The inherent efficiency of rail transportation, particularly for heavy bulk commodities such as grain, ethanol, plastic pellets, and aggregates, makes it the dominant form of transportation for long-haul bulk freight. One freight train can haul 200 cars or more, each with 100 tons of freight. It would take nearly 800 trucks to move the same amount of cargo.
Railway locomotives are also evolving to be more energy-efficient. Many now conform to EPA Tier4B requirements, have automatic engine shutdown, and computer-controlled engine management to monitor throttle settings. Trains are also not required to speed up and slow down as much as trucks, which helps them operate at more constant RPMs, minimizing fuel wastage.
The increased use of freight trains instead of trucks can provide significant benefits. Moving freight by rail reduces greenhouse gas emissions by 75%, reduces road congestion, and lowers roadway wear and tear, resulting in reduced road maintenance costs. According to CSX, converting just 10% of long-haul highway freight from trucks to rail would save 12 billion gallons of diesel fuel annually.

While the amount of fuel a freight train consumes depends on various factors, such as the type of train, its weight, design, speed, route, and engine efficiency, diesel-powered freight trains typically consume around 3 to 5 gallons of diesel fuel per mile. This equates to a train being able to haul 3,000 tons of freight 500 miles while consuming approximately 2,840 gallons of diesel fuel. According to CSX, this makes freight trains 3 to 4 times more fuel-efficient than moving freight on highways.
The fuel efficiency of freight trains has significant environmental implications. By reducing the number of trucks on the road, freight trains help decrease roadway wear and tear, reduce road congestion, and lower road maintenance costs. Additionally, freight trains produce substantially lower greenhouse gas emissions. Moving freight by rail instead of road reduces greenhouse gas emissions by an average of 75%. Converting just 5% of trucking freight to rail can eliminate 9 million tons of greenhouse gases, and if 10% of long-haul highway freight was converted to rail, it would save 12 billion gallons of diesel fuel annually.
The rail industry is also committed to improving fuel efficiency and reducing emissions. Freight railroads invest billions of dollars annually to enhance their climate resilience and sustainability practices. They employ advanced fuel management systems, anti-idling systems, and energy management systems to improve fuel efficiency and reduce fuel waste. Additionally, railroads are exploring the use of renewable and alternative fuels, such as renewable diesel, biodiesel blends, and battery-electric locomotives, with the goal of transitioning to low- and zero-emission technology.
Furthermore, freight trains are well-suited for long-haul routes, making them a strategic and environmentally responsible choice for transporting bulk freight over long distances. Their ability to carry a large volume of cargo in a single trip reduces the overall carbon footprint of freight transportation.
