Description
This unit involves the skills and knowledge required to maintain mechanical signalling locking and interlocking devices in accordance with safeworking and regulatory requirements, and workplace procedures. It includes diagnosing and correcting faults in the devices, and testing and adjusting the repaired equipment to meet workplace and manufacturer standards. People achieving competence in this unit will need to fulfil the applicable state/territory legislated rail safety requirements and to comply with relevant codes of practice and/or guidelines.Work is performed under minimal supervision, generally within a team environment. It involves the application of routine operational principles and procedures when maintaining mechanical signalling locking and interlocking devices, as part of workplace activities across a variety of operational contexts within the Australian rail system.No licensing, legislative or certification requirements apply to this unit at the time of publication.
