Zonegreen safety solutions for rail maintenance depots are both innovative, and ground- breaking.
Each solution is created following considerable research and development. These white papers provide the background to the state-of-the-art technologies:
Depot Protection Systems are installed in train maintenance facilities to control the safe movement of rail vehicles, protecting staff working in the vicinity. An analysis of the obligations of the safety functions performed by a Depot Protection System in a maintenance facility has concluded that a SIL 2 target level is required. A system can only be deemed as SIL compliant system if assessed as a whole, rather than relying on compliant COTS (commercial off-the shelf) components in a system using software of unknown pedigree (SOUP). Zonegreen’s DPPSTM has been assessed to meet the hardware and software requirements of SIL 2. DPPSTM uses standardised software and hardware across all installations, resulting in all DPPSTM installations meeting SIL 2. According to a recent study carried out by the Rail Safety and Standards Board (RSSB) shunter safety still remains a serious concern across the board in the UK rail industry. Occupational health risks that such a job entails are great. Operating heavy manual points, sometimes when standing on an uneven surface or working in poor conditions, could lead to lasting damage to the back, neck or shoulders, which not only causes the employee suffering and lost working days, but could also lead to a more serious accident. Some rail maintenance depots seem to look, and operate, as if they are still in the steam age. All very quaint, but how efficient are they, and even more important, how safe for depot staff? Over the past two decades, depot infrastructure has undergone changes which have clearly made a positive impact on safety. Better lighting arrangements, communication systems, access points, switches/crossings, signal sighting, fouling points and SPAD traps all contribute to increased safety. Driverless train systems are constantly growing in popularity and are bringing about huge changes in urban mass transportation. While there has been some degree of automation on rail networks for decades, the current trend towards fully automated and driverless networks shows no signs of hitting the buffers. The world’s longest driverless train network has turned to Zonegreen’s SMART DPPS™ to ensure the safety of depot staff. (all fields are required)
