As a transportation expert, I can provide an in-depth explanation of what a train runs on. Trains, as a mode of transportation, have evolved over the years, and their power sources have diversified. The statement that "Even diesel locomotives are actually diesel-electric generators that power the traction motors" is indeed correct. However, to understand the full picture, we must delve into the different types of trains and how they operate.
Steam Locomotives: Historically, the first trains were steam-powered. These engines burned coal or wood to heat water in a boiler, creating steam. The steam was then used to drive a piston system that turned the wheels. Steam locomotives were the primary mode of rail transport until the mid-20th century.
Diesel Locomotives: As the statement suggests, diesel locomotives use diesel fuel to power an engine that drives a generator. This generator produces electricity, which then powers electric motors known as traction motors. These motors are connected to the wheels and propel the train forward. Diesel-electric locomotives are self-contained, meaning they do not require external electrical power sources.
Electric Locomotives: These locomotives are powered by electricity supplied through overhead lines or third rails. The electricity is used directly to power the traction motors, eliminating the need for an on-board power generation system. Electric locomotives are often more efficient and environmentally friendly compared to their diesel counterparts.
Hybrid Locomotives: In recent years, there has been a push towards more sustainable and efficient transportation. Hybrid locomotives combine the benefits of diesel and electric power. They can operate on diesel power for flexibility and switch to electric power when connected to an electrified rail network.
Maglev Trains: A more advanced and specialized form of train is the Maglev (Magnetic Levitation) train. These trains use magnetic forces to levitate above the tracks, eliminating friction. They are propelled by linear motors, which use magnetic fields to move the train along the guideway. Maglev trains run on electricity and are known for their high speeds and smooth operation.
Infrastructure: Regardless of the power source, trains also rely on a complex infrastructure. This includes the tracks, which provide a stable and guided path for the train to follow. The track system must be able to support the weight and speed of the train, and it is designed to minimize resistance and optimize the train's performance.
In conclusion, while it is true that trains ultimately run on electricity, whether it is generated on board or supplied externally, the specific power source and technology can vary greatly. From the historical steam engines to the modern electric and hybrid locomotives, trains represent a diverse range of technologies designed to move people and goods efficiently and safely.

Even diesel locomotives are actually diesel electric generators that power the traction motors. Since it is eventually electricity that powers the wheels, trains run on electricity.
