Maintain aerial signal/telecommunications lines and cables

Assessment tool

Version 1.0
Issue Date: May 2024


Persons achieving competence in this unit will need to fulfil the applicable legislated rail safety requirements including acts and regulations from each state and territory together with any nationally approved compliance codes and/or guidelines.

Work is performed under minimal supervision, generally within a team environment. It involves the application of routine operational principles and procedures to the maintenance of aerial signal/telecommunications lines and cables as part of workplace activities across a variety of operational contexts within the Australian rail system.

Operators of mechanised equipment must have undertaken training and, where appropriate, hold the relevant licence, permit or certificate and be recognised as competent for the class of machinery being used.

This unit involves the skills and knowledge required to maintain aerial signal/telecommunications lines and cables in accordance with safeworking and regulatory requirements and workplace procedures, including inspecting and servicing line and cable routes, diagnosing any identified line and cable faults and repairing any line and cable faults to the standards specified to ensure system integrity. Licensing, legislative, regulatory or certification requirements are applicable to this unit.

Routes are inspected and recorded and arrangements are made for the removal of any obstructions, damage, infringing vegetation to provide free access to cables/aerials 
Routes are physically inspected to determine any breaks, misalignments, damage and insulation wear requiring repair 
Poles are inspected for deterioration and a safety assessment is made 
Permission to test isolated equipment is confirmed prior to any work being undertaken 
Probable location of fault is identified from visual inspection and circuit tests are conducted to isolate fault area 
The nature of the fault is identified from further tests and corrective action required is identified to enable appropriate arrangements for resources and for work to be performed 
Disconnection/insulation procedures are applied to enable maintenance work to be carried out in isolation to systems where lines are in close proximity to high voltage services 
Work site is made safe in accordance with organisations safety requirements to enable repair work to be safely undertaken 
Aerial lines/cables are repaired to operational and technical requirements using appropriate jointing or replacement/repair procedures 
Repaired/replaced line/cable is tested to specified standards to ensure conformity to operational and technical requirements
