10 Days
Maximum number of delegates: 


This course is intended for experienced signal designers and testers who wish to progress towards the design or testing of complex signalling logic.

 Key Features

  • Course fully up to date to reflect current requirements
  • The course concentrates on understanding of interlocking functionality, as well as “filling in the boxes”
  • The delegate will benefit from experimentation on our demonstration interlockings
  • Technical jargon is explained in clear English terms
  • “intermediate” level concepts are thoroughly revised before advancing to the “advanced” subjects

Course Outcomes

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

  • Perform Headway Calculations for stopping trains
  • Calculate the effects of variable gradients upon signal spacing and achievable headway
  • Identify acceptable mitigations for under and over braking
  • Identify acceptable aspect sequence transitions
  • Specify controls for tunnel, closing-up and mid-platform signals
  • Specify controls for distant and banner repeater signals
  • Specify controls for complex junction signalling arrangements
  • Specify controls for last wheel replacement
  • Identify situations where duplicate copies of information may cause safety issues
  • Specify controls for foul track circuits and diamond crossings
  • Identify and specify the need for track circuit timers.
  • Specify controls for platform sharing
  • Specify controls for preset and preceding shunt signals
  • Specify controls for Comprehensive Approach Locking
  • Specify controls for Train Operated Route Release
  • Specify controls for complex overlaps

Assessment and Certification

Achievement of the Course Outcomes will be assessed by a theory assessment to demonstrate the underpinning knowledge gained

The delegate’s achievement of the Course Outcomes will be confirmed by a certificate which will be forwarded to the nominated client contact following the course.


A well prepared delegate is expected to be able to interpret signalling plans, demonstrate an understanding of standard interlocking principles, and complete control tables for simple routes and points.
