Certificate of Attendance

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

Who Should Attend This Course?

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

Course Content and Learning Outcomes

At the end of this course the successful delegate will be able to specify complex signalling arrangements on Signalling Plans and Control Tables, relating to:
