What is signal engineering?

Signal engineering is a specialized field focused on designing, installing, maintaining, and managing railway signaling systems that ensure the safe and efficient movement of trains. Signal engineers work with technologies that control train traffic, such as track circuits, interlockings, and communications equipment, to prevent collisions and manage rail traffic flow. Their responsibilities also include upgrading existing systems to meet modern safety standards and integrating new technologies like automation and digital controls. This role is critical for railway safety, reliability, and the smooth operation of passenger and freight services.
