Entry Requirements:

To become a Signalling Technician, you should focus on subjects that provide a strong foundation in technology, electronics, and problem-solving. Signalling Technicians are typically responsible for maintaining and repairing signalling systems, which are crucial for the safe operation of railways and other transport systems. Here are some subjects to consider:

  1. Mathematics: Mathematics is essential as it helps develop problem-solving skills, which are crucial in the maintenance and repair of signalling systems. It’s also important for understanding technical manuals and specifications.
  2. Science (Physics or Electronics): Science subjects, especially physics or electronics, will provide a foundation for understanding electrical circuits and electronic components used in signalling systems.
  3. Design and Technology or Engineering: These subjects can provide practical knowledge and skills related to working with machinery, electrical systems, and technical drawings, which are relevant to signalling technician roles.
  4. Information and Communication Technology (ICT): Proficiency in ICT is important because signalling systems are increasingly computer-based. Understanding software and digital technology is beneficial.
  5. English: Good communication skills are essential when working as part of a team or when dealing with documentation, reports, and communicating about system issues.
