This TI relates to a change in the number of supplementary detection elements when S&C units are being renewed. A change may arise from a change in point operating mechanism, rail profile or switch type. It applies to signalling designers, testers, and project engineers.
Purpose
A change to the number of detection elements associated with a set of points can require significant documentation and testing. This instruction provides rules to enable efficient renewals and upgrades of S&C layouts.
