HRD function tester

HRD Function Tester–Locations

The HRD Function Tester–Locations training course is for persons in a function tester role or those who are about to enter the role.

This non-accredited course provides participants with the fundamental principles and practices to test and verify that the signal control circuits function as intended according to the design circuits and that they comply with fundamental signalling principles.


Participants should be employed in related areas of rail so that they have exposure to railway signalling control circuits and associated signalling equipment.

About the program

Course delivery includes both in-class theory and practical learning.

Practical exercises consist of:

  • application of the rail operator’s testing standards, supported by experimentation on a variety of simulated signalling circuits located within a relay room or a location case
  • the use of rail signal control circuit drawings/diagrams
  • the use of testing tools and instruments to test sample circuits completion of relevant test certificates (or part thereof).

On conclusion of training, participants each complete an on–the–job practical assessment to confirm competence.

The Function Tester course is based on the Rail Network Signalling Works Testing Handbook (NR/SP/SIG/11221) as well as other testing documents relevant to the rail authority jurisdiction that applies to this training.

Course outcomes

Upon successful completion of this course, participants will be able to:

  • identify and apply the relevant testing procedures
  • identify the relevant test certificates
  • test rail signal power supplies
  • conduct circuit function and strap and function tests within a location
  • conduct changeovers and associated tests
  • conduct through–circuit testing
  • test track circuits
  • test point installations
  • test signals and associated equipment
  • test CBI inputs and outputs associated with the location
  • identify and report pass results
  • complete relevant sections of the test certificates.

Course duration

Function tester courses are conducted over 6 days (5 days training, 1 day assessment).

Courses run on an as–needed basis, so register your interest or enquire with HRD about the next available course.
