14593  Control rail movement by operating semaphore signals and Indicators on on single lines  Level 5  Level TBA: Pre-2009 was L5  Complete 

PURPOSE OF THE UNIT STANDARD 
A learner will be able to control the safe movement of trains and shunting movements on single lines by operating semaphore signals and indicators according to related operating standards and procedures in a specific railway environment.

The qualifying learner will be capable of:
  • Describe the station control layout.
  • Plan rail movement.
  • Operate lever-frame of semaphore signals and indicators.
  • Apply station opening and closing procedures. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
  • Communication at NQF Level 3.
  • Mathematical Literacy at NQF Level 3. 

  • UNIT STANDARD RANGE 
    Semaphore signals includes indicators, and the words may be interchanged.

    SPECIFIC OUTCOME 1 
    Describe the station control layout. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The station layout is explained in terms of the station diagram. 

    ASSESSMENT CRITERION 2 
    Physical positions of semaphore signals are identified from the diagram. 

    ASSESSMENT CRITERION 3 
    The location of semaphore signals is explained in terms of their appearance, purpose and functionality. 

    SPECIFIC OUTCOME 2 
    Plan rail movement. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    Rail movement information for a specific train is gathered in terms of approaching train(s). 

    ASSESSMENT CRITERION 2 
    Rail movement running times are calculated in accordance with train running times and scheduled plan. 

    ASSESSMENT CRITERION 3 
    The application of signals and indicators are planned in accordance with immediate traffic requirements. 

    SPECIFIC OUTCOME 3 
    Operate lever-frame of semaphore signals and indicators. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The lever-frame layout is explained in terms of its operation. 
    ASSESSMENT CRITERION RANGE 
    Layout includes but is not limited to colour coding of levers and order for lever operation.
     

    ASSESSMENT CRITERION 2 
    The manner in which the lever-frame interlocks with signals and points is explained in terms of the sequence of operation. 

    ASSESSMENT CRITERION 3 
    Levers for semaphore signals and indicators are operated and secured in accordance with operating standards and procedures. 

    ASSESSMENT CRITERION 4 
    Levers for points and locking bars are operated and secured in accordance with operating standards and procedures. 

    ASSESSMENT CRITERION 5 
    Signal reaction to lever positions is observed and confirmed to be in accordance with the expected outcome. 

    ASSESSMENT CRITERION 6 
    The system is operated in degraded mode in accordance with standard operating procedures. 

    SPECIFIC OUTCOME 4 
    Apply station opening and closing procedures. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    Neighbouring stations and Operating Centre are informed about station closing in accordance with standard operating procedures. 

    ASSESSMENT CRITERION 2 
    Points, signals and signal lights are operated for the closing or opening of a station in accordance with standard operating procedures. 

    ASSESSMENT CRITERION 3 
    Stations are signed on or off in accordance with standard operating procedures. 
    ASSESSMENT CRITERION RANGE 
    Procedures include but are not limited to informing neighbouring stations, gathering train information, securing the interlocking key, inspecting points and station equipment.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    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.
