How Much Fuel Do Road Trains and Locomotives Hold?

When it comes to moving heavy loads, whether they are on the ground with a road train or on the rails with a locomotive, the amount of fuel required can vary greatly. In this article, we will delve into the fuel capacities of different locomotives and road trains, providing a clearer understanding of the logistics behind these massive vehicles.

Locomotive Fuel Capacities

The fuel capacity of locomotives can range significantly depending on their design and purpose. Here’s a breakdown of some of the most common types of locomotives used in North America:

SD40-2 Locomotive

The SD40-2 locomotive, a staple of North American railroads in the past, is known for its robust performance. This standard line-haul workhorse can hold between 3200 to 4000 US gallons of diesel fuel. Each gallon is expressed in US gallons.

EMD MP 1500 Switching Locomotive

The EMD MP 1500, a standard switching locomotive, holds a more modest 1100 to 1400 US gallons of diesel fuel. These locomotives are primarily used for shunting operations in and around train yards.

GE AC Locomotives

More recently, advanced diesel-electric AC locomotives, such as the GE AC4400CW, have entered the market. These modern engines can hold a substantial amount of fuel, typically around 5000 US gallons, which translates to a significant range for the trains they power.

Extra Fuel Tanks: The Heart of the Locomotive

Underneath the locomotive, a massive fuel tank provides the critical support for its operations. This tank can hold up to 5500 US gallons (20820 liters) of diesel fuel, with an additional 300 gallons (1135 liters) reserved for coolant and 250 gallons (946 liters) for engine oil. This design ensures that the locomotive remains operational for long periods without refueling.

Comparing Fuel Capacities: Road Trains vs. Locomotives

For road transport, the fuel capacity of a road train can also be impressive, especially when considering the sheer size of these vehicles. A typical Australian road train can carry approximately 130,000 liters of diesel fuel, with an additional 2,000 liters stored internally.

The Most Popular Freight Engine in the US

The GE Dash 8-40CW, one of the most popular freight engines in the United States, can hold 5000 US gallons of diesel fuel, which is equivalent to around 4200 Imperial gallons. However, as most trains use multiple engines, the total fuel capacity for a train can range from 10,000 to 20,000 US gallons.

Understanding the fuel capacities of different locomotives and road trains helps in optimizing the transportation of goods across vast distances. Whether it’s a long-haul road train or a powerful locomotive, the ability to carry large amounts of fuel is crucial for ensuring smooth and efficient operations.
