How Much Fuel Does A Train Hold?
Trains are an efficient and environmentally friendly way to transport large volumes of freight and passengers over long distances. An important consideration in running trains is how much diesel fuel they can carry to power their journeys.
If you’re short on time, here’s a quick answer to your question: a freight train can hold between 5,000 to 12,000 gallons of fuel in multiple locomotive fuel tanks. The exact capacity depends on the train size and number of locomotives.
In this comprehensive guide, we’ll explore key factors like train types, fuel tank capacities per locomotive, number of locomotives per train, and total fuel consumption to help you understand just how much diesel trains require to run.
Fuel Tank Capacities By Locomotive Type
Modern Diesel Locomotives
Modern diesel locomotives are designed to be more efficient and environmentally friendly. They are equipped with larger fuel tanks to allow for longer journeys without refueling. On average, a modern diesel locomotive can hold anywhere between 5,000 to 10,000 gallons of fuel.
This capacity can vary depending on the specific model and manufacturer.
For example, the General Electric Evolution Series locomotives, which are commonly used in freight transportation, have a fuel tank capacity of around 4,000 gallons. On the other hand, the Siemens Charger locomotives, which are often used in passenger transportation, can hold up to 6,000 gallons of fuel.
It’s important to note that these figures are approximate and can vary based on factors such as train weight, operating conditions, and fuel efficiency. However, the larger fuel tank capacities of modern diesel locomotives allow for fewer refueling stops and increased efficiency in long-distance travel.
Older Diesel Locomotives
Older diesel locomotives typically have smaller fuel tank capacities compared to their modern counterparts. These locomotives were designed during a time when fuel efficiency and environmental concerns were not as high of a priority.
On average, older diesel locomotives have a fuel tank capacity ranging from 2,000 to 4,000 gallons. However, it’s important to note that there are exceptions to this range, with some older locomotives having larger fuel tanks depending on their specific design and purpose.
For example, the EMD SD40-2 locomotive, which was widely used in the United States during the 1970s and 1980s, had a fuel tank capacity of around 3,800 gallons. This allowed the locomotive to travel approximately 300 miles before needing to refuel.
As technology has advanced, newer locomotives have been designed to be more fuel-efficient and capable of longer journeys. Therefore, it is not uncommon for older locomotives to require more frequent refueling compared to their modern counterparts.
Number of Locomotives Per Freight Train
One important factor that determines the amount of fuel a train holds is the number of locomotives it has. The number of locomotives in a freight train can vary depending on various factors such as the weight of the train, the terrain it will be traveling through, and the distance it needs to cover.
Factors Affecting the Number of Locomotives
1. Train Weight: The weight of a freight train plays a crucial role in determining the number of locomotives required. Heavier trains require more power to move, so they often have multiple locomotives attached to distribute the load and provide sufficient traction.
2. Terrain: The type of terrain the train will be traversing also affects the number of locomotives needed. Steep inclines or mountainous regions may require additional locomotives to ensure the train can climb the slopes without losing momentum.
3. Distance: The distance the train needs to cover can also impact the number of locomotives. Longer journeys may require more locomotives to ensure a consistent speed and to account for any unexpected delays or stops along the way.
Comparison with Passenger Trains
Freight trains typically have more locomotives compared to passenger trains due to the heavier weight they carry. While passenger trains may have only one or two locomotives, freight trains can have several locomotives connected together to provide the necessary power to move the heavy cargo.
Statistical Data (Optional)
According to a report by the Association of American Railroads, the average number of locomotives in a freight train in the United States is around 2 to 3. However, this number can vary significantly depending on the factors mentioned earlier.
Train Type | Average Number of Locomotives |
---|---|
Intermodal | 2-4 |
Coal | 3-6 |
Container | 2-3 |
These numbers are just averages and may not apply to every freight train. The actual number of locomotives can vary based on the specific requirements of each train.

Fuel Consumption Rates of Locomotives
When it comes to fuel consumption, locomotives vary depending on several factors such as the type of locomotive, its age, and the load it is pulling. The fuel consumption of a train is measured in gallons per mile (GPM) or liters per kilometer (LPK).
Diesel Locomotives
Diesel locomotives are the most commonly used type of locomotive, especially in freight transportation. These locomotives use diesel fuel, which is stored in onboard fuel tanks. On average, a diesel locomotive can consume anywhere from 0.6 to 1.5 gallons of fuel per mile, depending on the load and terrain.
It is important to note that newer diesel locomotives are designed to be more fuel-efficient compared to older models. With advancements in technology, modern diesel locomotives have better fuel injection systems, aerodynamics, and overall engine efficiency, resulting in lower fuel consumption.
Electric Locomotives
Electric locomotives are powered by electricity and do not require onboard fuel tanks. Instead, they receive power from an overhead wire system or a third rail. As a result, their fuel consumption is minimal, as they do not burn any fuel directly.
However, the electricity used to power electric locomotives is generated from various sources, including fossil fuels, nuclear energy, and renewable sources.
It is worth mentioning that electric locomotives offer several advantages over diesel locomotives. They have lower operating costs, produce less noise and air pollution, and can deliver consistent power output.
These factors make electric locomotives a popular choice for passenger rail systems in urban areas.
Comparison with Other Vehicles
When comparing the fuel consumption of trains to other modes of transportation, trains are generally more fuel-efficient. For example, a typical passenger car can consume around 25 miles per gallon of fuel, while a train can transport hundreds of passengers and goods while using only a fraction of that fuel.
It’s also important to consider the energy efficiency of trains when transporting large amounts of goods. Trains are capable of hauling significantly more weight compared to trucks, resulting in fewer trips and less fuel consumption overall.
Total Fuel Capacity of a Freight Train
Freight trains are the backbone of the transportation industry, carrying tons of goods across vast distances. To power these massive trains, they require a significant amount of fuel. The total fuel capacity of a freight train varies depending on several factors, including the size and type of locomotives used.
Types of Locomotives
Freight trains typically consist of multiple locomotives working together to pull the heavy loads. Different types of locomotives have different fuel capacities. For example, modern diesel locomotives, which are commonly used in freight trains, can hold anywhere from 2,000 to 5,000 gallons of fuel.
These locomotives are designed to be fuel-efficient and can travel long distances without refueling.
On the other hand, older steam locomotives, which are now mostly used for heritage or tourist trains, had much larger fuel capacities. These behemoths could carry up to 20,000 gallons of water and coal, which were used to generate steam to power the engine.
Fuel Efficiency
While the total fuel capacity of a freight train is important, so is its fuel efficiency. Freight companies are constantly looking for ways to improve fuel efficiency to reduce costs and minimize their environmental impact.
This includes utilizing technologies such as hybrid locomotives, regenerative braking systems, and advanced aerodynamics.
According to the Association of American Railroads, freight trains are already one of the most fuel-efficient modes of transportation. On average, a single gallon of diesel fuel can move a ton of freight over 200 miles, making trains an environmentally friendly option for long-haul transportation.
Refueling and Maintenance
Considering the large fuel capacity of freight trains, refueling is not a frequent task. However, when it’s time to refuel, specially equipped fueling stations are used. These stations have high-capacity pumps and tanks to accommodate the needs of the trains.
The refueling process is carefully managed to ensure efficiency and safety.
In addition to refueling, routine maintenance is crucial to keep the trains running smoothly. This includes regular inspections, oil changes, and engine tune-ups. By keeping the locomotives in good condition, freight companies can maximize fuel efficiency and minimize downtime.

Conclusion
In summary, a modern diesel freight train hauling cargo can hold between 5,000 to 12,000 gallons of fuel across multiple locomotive fuel tanks. Older trains may have smaller capacities, while modern efficient locomotives can maximize range.
There are many variables at play, but this fuel powers these heavy trains over incredible distances day and night.
