Railway locomotives are powerful vehicles designed to pull trains along tracks. They are equipped with engines that generate the necessary force to move heavy loads, such as freight or passenger cars. Locomotives can be powered by various sources, including diesel engines or electricity from overhead lines. These machines come in different types, such as steam locomotives, which use steam to create power, and electric locomotives, which rely on electricity. Locomotives play a crucial role in the transportation industry, enabling efficient movement of goods and people across long distances.
