Locomotive manufacturing involves the design and production of trains that are powered by engines, typically used for transporting goods and passengers. This process includes various stages such as engineering, assembly, and testing to ensure safety and efficiency. Manufacturers often use advanced technologies and materials to enhance performance and reduce environmental impact. The industry is supported by a network of suppliers providing components like engines, wheels, and braking systems. Major companies in this field include General Electric and Siemens, which play significant roles in developing innovative locomotives that meet modern transportation needs.
