Train Arrived Complete – The authorised memeber of traincrew will operate the Train Arrived Complete switch located on the platform on which a train has arrived complete with tail lamp, under absolute block signalling when the train has not passed the signal box for the signaller to observe the tail lamp. This may be because the signal box is in advance of the platform of arrival in the direction of travel of the train. This will enable the signaller to give “Out of Section” to the signaller in rear.
