GKGN0644 Iss 2

This document provides guidance to support the requirements associated with signalling a second train onto a section of railway line which is already occupied by a train. New guidance in issue two explains a change to the requirements for the approaching train to be at a stand, or nearly at a stand before the calling-on movement authority. The changes enable operational efficiencies to be achieved by allowing the calling-on movement authority to be displayed when the approaching train is within 100 m of the signal and the speed of the train is consistent with the driver transitioning to the permissive movement.
