Qualification -
Unit of Competency TLIW2012A - Grind rails
Description This unit involves the skills and knowledge required to grind rail and welds in accordance with approved 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. Licensing or certification requirements are not applicable to this unit.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application 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 some supervision, generally within a team environment. It involves the application of routine operational principles and procedures to the grinding of rail and welds as part of workplace activities across a variety of operational contexts within the Australian rail system.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.
