London Underground platform to train CCTV studies

When one person (train) operation was introduced it was necessary to install equipment within the confines of tunnels, platforms and trackside and indeed within the rolling stock itself, to provide a method of safe operation at the platform to train interface. This has and still does present major challenges associated with the wide range and diversity of platforms and structures on the underground. The paper gives a historical and in depth view of how these problems have been overcome and the issues associated with providing CCTV to ensure a safe transition at the platform to train interface. In particular it focuses on the platform to train CCTV study and demonstrate how continuous improvements have been applied to each successive system.
