Where required in the Rule Book, the signaller is required to confirm, normally by observation of the tail lamp from the signalbox, that a train has arrived complete before accepting a second train from another signalbox or allowing a second train onto a single line. Where it is proposed that a signaller shall not directly observe that the train is complete then one alternative means is the use of a tail light camera.

This specification applies to all signalling schemes and detailed design where it is proposed to introduce or amend a tail light camera in order to enable a signaller to confirm that a train has arrived complete..

Tail lamp cameras for the use of signallers to fulfil requirements of the block regulations shall be managed and maintained as a signalling asset.
