Course Details

WHO SHOULD ATTEND
Delegates who need to refresh their understanding of the operation and faulting techniques used on Westpac Geographical interlocking systems. Delegates must have successfully attended the full Westpac Geographical interlocking event.

OBJECTIVES
On successful completion of the course delegates will be able to:
• Explain system operation
• Locate and rectify faults in the various levels and stages of route setting/releasing

CONTENT
• Geographical system principles
• System construction
• PBI and push button circuits
• Route selection circuits
• Calling and locking circuits
• Point setting and locking
• Route releasing including TORR
• Overlaps
• Flank protection
• Control panel and indication circuits
• Use of fault finding procedure
• Fault finding practice

LEARNING APPROACH
Classroom sessions, practical demonstrations and fault finding sessions on a working Westpac system.
50% of this course is spent on practical work.

FEATURES
Delegates have an opportunity to refresh/develop fault-finding skills on a complex interlocking without compromising the safety of a working interlocking. The skills obtained allow the rapid resolution of potentially costly failures on lineside systems.
The use of a system not connected to a working railway allows the introduction of a range of faults giving the delegate the maximum experience of potential failures.
