Diesel locomotives are powerful trains that use diesel engines to generate the energy needed for movement. Unlike steam locomotives, which rely on coal or wood, diesel engines burn fuel to create electricity or directly drive the wheels. This makes them more efficient and easier to maintain. These locomotives are commonly used for both freight and passenger transport. They can operate on tracks without the need for electrification, making them versatile for various rail systems. Diesel locomotives have become a standard choice in many countries due to their reliability and cost-effectiveness.
