This unit involves the skills and knowledge required to decommission electrical and electromechanical rail signalling from service on rail networks.

It includes preparing to withdraw electrical and electromechanical rail signalling from service. It also includes completing disconnection of operating and redundant circuitry, equipment and components; testing of remaining circuitry and equipment; finding and repairing faults; testing of control and indicating equipment; and reporting.

Persons achieving competence in this unit will need to fulfil the applicable state/territory legislated rail safety requirements and comply with relevant codes of practice, rules and/or guidelines.

No other licensing, legislative or certification requirements apply to this unit at the time of publication.

applying sustainable energy principles and practices

decommissioning electrical and electromechanical rail signalling from service in accordance with workplace procedures

preparing to decommission electrical and electromechanical rail signalling from service

withdrawing electrical and electromechanical rail signalling from service.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

electrical and electromechanical rail signalling decommissioning, safe working practices and relevant standards, codes and regulations, including:

purpose of decommissioning

decommissioning planning and documentation

decommissioning requirements and hazards

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in suitable rail workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in suitable rail simulated workplace operational situations that replicate workplace conditions.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Resources for assessment must include access to:

a range of relevant exercises, case studies and/or other simulations

relevant and appropriate materials, tools, facilities, equipment and personal protective equipment (PPE) currently used in industry

resources that reflect current industry practices in relation to decommissioning electrical and electromechanical signalling from service

applicable documentation, including workplace procedures, equipment specifications, regulations, codes of practice and operation manuals.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Range is restricted to essential operating conditions and any other variables essential to the work environment.
