This standard applies to OPO CCTV systems specifically designed and used for the capture of Real Time images of the Platform Train Interface (PTI) for display in Real Time on the platform or in the train cab, in order that the Train Operator or the Operational Control Centre (OCC) staff undertaking controller assisted dispatch duties can mitigate to As Low As Reasonably Practical (ALARP), the risks for safe dispatch of the train from the platform in all driving modes, in any direction.

Purpose

The purpose of this standard is to define the operational and technical requirements for a consistent configuration of image capture, logical presentation and system performance in order to mitigate the risk at the Platform Train Interface (PTI) using only Closed Circuit Television (CCTV) equipment.
