Zonegreen Showcases Safety Upgrades at Railtex

Rail safety specialists, Zonegreen, will be exhibiting their market leading depot protection system at Railtex/Infrarail next month, to highlight its most recent developments.

The Sheffield-based firm will be at Birmingham’s NEC from September 7-9 to demonstrate its Depot Personnel Protection System (DPPS) in person for the first time since the pandemic.

Visitors to Zonegreen’s stand N02 in hall 11 of the NEC will be able to see first-hand how rail depot staff are protected by the automated system, which creates safe zones in which they can work and prevents vehicle movements until roads are recognised as clear.

DPPS is installed in some of the most advanced rail maintenance facilities in the UK and has recently been independently certified to meet the hardware safety integrity requirements of SIL2. This is a measurement of the performance needed for a safety instrumented function and is defined by assessing the relative levels of risk reduction it provides.

Although there is no defined SIL requirement for depot protection, some alternative products integrate an off-the-shelf SIL2 PLC into an otherwise untested system. However, Zonegreen has subjected the whole of DPPS to the functional safety assessment, demonstrating its commitment to improving the depot environment for maintenance workforces.
