Form RT3193 Iss 12-25

This form is used by the signaller to record the arrangements for implementing single line working.

This form has been updated in line with project work reducing the use of detonators which has also removed the requirement for a handsignaller at the end of the single line working section. Wording on the form has been amended to reflect the changes and now reads ‘end of degraded working sign’ in place of any reference to handsignallers, or the addition of ‘intermediate’ to any handsignallers that remain for divided sections.
