This course will enable signalling designers to create control tables for signalled routes and points, using standard control tables for Route Relay Interlockings.

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
  • Also provides preparation for module 3 of the IRSE examination

Course Outcomes

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


  • Demonstrate an understanding of interlocking principles
  • Complete control tables for signalled routes and points

Assessment and Certification

Achievement of the Course Outcomes will be assessed by a theory assessment of interlocking principles and control table completion.


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 and show a basic understanding of signalling principles for UK main line signalling installations.
