Geographical Interlocking – Refresher B (GEC – General Signal)

Duration: 5 Days

Division: Signal Maintenance

Course code: GCBR

Venues: Clapham or Derby

Who Should Attend

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

Objectives

On successful completion of the course the delegate will be able to correctly:

•  Explain the operation of the system
•  Fault find system failures

Content

•  Geographical system principles
•  System construction
•  Common control set and push button circuits
•  Selection level circuits
•  Locking level circuits
•  Aspect level circuits
•  Route releasing and locking level
•  Overlaps
•  Flank protection
•  Control panel and indication circuits

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.
