In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This qualification does not replace any other qualification and is not replaced by any other qualification. 

The purpose of this qualification is to prepare a learner to operate as a Railway Signalling Installer. A Railway Signalling Installer installs signalling equipment for the safe running of trains.
A qualified learner will be able to:
  • Install signalling equipment.

    The South African government has set as a priority the shifting of as much traffic as possible - both freight and passenger services - from the road to rail. This move necessitates the timely development of the critical competencies of all services closely related to efficient functioning of both freight and passenger train services, and Railway Signalling Maintenance Mechanician is a significant component of these services. Efficiencies in transport systems are closely related to positive socio-economic changes. The reliable functioning of all railway equipment and systems to ensure the safe running of trains are at the core of this relationship. Economic opportunities are likely to increase where train infrastructure systems are geared towards efficient functioning to ensure access to markets and related economic opportunities.
    Efficiently operated rail transport system will reduce the volume of road traffic pressures on our roads. When more volumes move by motor powered rolling stock supported by efficient signal equipment and systems, more jobs will be created as this ensures economic growth.

    Persons operating within the rail transport industry, as well as other transport services, will benefit from all aspects of this qualification (theoretical, practical and work experience competencies) as it is needed to render effective and efficient rail transport services.These services are essential for operational requirements of all train services entering South Africa from neighbouring countries. As such, this qualification is essential to set the benchmark for all Railway Signalling Installers operating in South Africa as well as neighbouring countries.
    The range of typical learners will, therefore, come from within the rail environment, from other sectors and outside the country. The Railway Signalling Installer is part of a suit of occupational qualifications that has been developed by the rail sector to provide a learning pathway which includes the Train Control Officer, Electricians, Train Driver and other related occupations within the railway environment.

    Integrated Assessment
    Integrated formative assessment
    The skills development providers will use the curriculum to guide them on the stipulated internal assessment criteria and weighting. They will also apply the scope of practical skills and applied knowledge as stipulated by the internal assessment criteria. This formative assessment leads to entrance into the integrated external summative assessment.

    Integrated summative assessment
    An external integrated summative assessment, conducted through the relevant QCTO Assessment Quality Partner is required for the issuing of this qualification. The external integrated summative assessment will focus on the exit level outcomes and associated assessment criteria.

    The assessment will be conducted through written assessment and the evaluation of practical tasks at decentralised approved assessment sites by a panel of assessors evaluated by assessor(s) registered with the AQP within a period of 1 day.

    To qualify for an external assessment, learners must provide proof of completion of all required modules by means of a statement of results and statement of work experience as well as proof of successful completion of the following subjects and modules or alternative programmes where applicable including Foundational Learning Competence. 

    An international comparability study was undertaken to evaluate a selected number of comparable qualifications from various countries in terms of their scope, levels and curriculum content.

    International qualifications from Australia and the United Kingdom (UK) were used for this comparability study.

    In Australia, the Industry Skills Council offers a Certificate in Mechanical Rail Signalling III and is assumed to be equivalent to NQF level 3, with conditional entry being Certificate II in Rail Infrastructure. The certificate covers a total of 18 units of competency comprising: 11 core units and selection of 7 from 15 elective units. The core units are: Carry out measurements and calculations, Read and interpret plans and job specifications; Service and clean mechanical signalling equipment and infrastructure; Repair and adjust mechanical signalling equipment and infrastructure; Carry out off-site repair, overhaul and assembly of mechanical signalling equipment; Maintain mechanical signalling locking and interlocking devices; Test mechanical signalling equipment and isolate faults; Process workplace documentation; Apply awareness of safe working rules and regulations; Use info technology devices in the workplace and Install mechanical infrastructure for signalling.

    The content of this qualification focuses exclusively on mechanical components of the railway signal and does not cover the electrical component which is rather significant for the occupational certificate. Significant aspects covered in the core units are addressed in the several components of the occupational certificate.

    A one-year certificate in railway operations offered in the UK is closely comparable to the Occupational Certificate: Railway Signalling Maintenance Mechanician. The certificate covers the following modules: Becoming a Reflective Practitioner, Railway Operating principles, Railway business organisation, railway systems, Railway customer service, safety law and management, train planning and performance management, managing people and lastly integrated work-based learning project.

    There are modules like railway operating principles, railway system as well as safety law and management that cover aspects very much similar to those covered in the occupational certificate. However, the rest of the modules addresses overall management of the railway operations and not signal operations per se. Although somewhat comparable in some instances, the broader thrust of this qualification is not comparable to the occupational certificate.

    It cannot be concluded that the qualifications identified from different countries are represented and a fair reflection of similar qualifications. Similarities from the countries identified are limited in scope to issues of safety, signal system, and their operations. However, there are no similarities in terms duration, entry requirements and the exit levels. 

    This qualification allows possibilities for both vertical and horizontal articulation.
    Horizontal Articulation:
  • Occupational Certificate Railway Signalling Assembler and Wirer, NQF Level 3.

    Vertical Articulation:
  • Occupational Certificate: Railway Signalling Fault Finder and Maintainer, NQF Level 4.
  • Occupational Certificate: Railway Signaling Maintenance Mechanician, NQF Level 4. 

  • NOTES 
    Qualifying for External Assessment:
    To qualify for an external assessment, learners must provide proof of completion of all required modules by means of statements of results and work experience records.

    Additional legal or physical entry requirements
  • None.

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
