This unit involves the skills and knowledge required to grind rail and welds in accordance with rail industry standards, safeworking and regulatory requirements, and workplace procedures.

It includes determining job requirements, grinding weld and/or weld repair, grinding rail to repair surface defects, and completing all required documentation. This competency relates to the grinding of new welds and weld repairs, wheel burns, rail batter and overflow in plain track.

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 some supervision, generally within a team environment. It involves the application of routine operational principles and procedures when grinding rail and welds, 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.

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria on at least three  separate occasions and include:

• applying grinding techniques to achieve rail profile and surface condition to meet requirements of rail industry standards and procedures
• applying relevant safeworking system and workplace procedures
• grinding welds and weld repairs using appropriate grinding wheel speed and rate of metal removal
• identifying job hazards and taking required action to minimise, control or eliminate identified hazards
• identifying job requirements
• implementing contingency plans
• interpreting and following operational instructions and prioritising work
• modifying activities depending on operational contingencies, risk situations and environments
• monitoring work activities in terms of planned schedule
• operating and adapting to differences in equipment in accordance with operating procedures
• operating grinding equipment safely
• reading and interpreting relevant technical data, drawings, instructions and manuals
• reporting and/or rectifying identified problems, faults or malfunctions, in accordance with workplace procedures
• selecting and using hand tools, power tools and equipment
• working systematically with required attention to detail without injury to self or others, or damage to goods or equipment.

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:

• accepted rail industry standards for rail profile and surface condition
• documentation and record keeping requirements
• grinding methods and results
• hazards that may exist when grinding rail and welds, and ways of controlling the risks involved
• manufacturer instructions and workplace procedures for operating grinding equipment
• problems that may occur when grinding rail and welds, and action that can be taken to report or resolve these problems
• relevant safety, work health and safety (WHS)/occupational health and safety (OHS) and environmental procedures and regulations
• relevant safeworking systems and operational procedures
• workplace procedures for grinding rail and welds.

As a minimum, assessors must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

As a minimum, assessment must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in workplace operational situations or, where this is not available, in simulated workplace operational situations that replicate rail corridor 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 include:

• a range of relevant exercises, case studies and/or simulations
• relevant and appropriate materials, tools, equipment and personal protective equipment currently used in industry
• applicable documentation including workplace procedures, regulations, rail industry standards, codes of practice and operation manuals.
