Zonegreen has installed its flagship Depot Personnel Protection System (DPPS) at Aberdeen’s Clayhills facility for LNER, to ensure staff are protected from unauthorized vehicle movements.
Zonegreen has replaced the existing life-expired depot protection on Clayhill’s single shed road with DPPS, fitting its Network Rail approved derailers to safeguard staff. Workers log onto the system via intuitive road end control panels, which prevent the derailers from being lowered, creating a safe zone in which to work. The project is also the first installation since DPPS was independently certified to meet the hardware safety integrity requirements of SIL2.
By automating safety procedures and removing the margin for human error, DPPS creates a safe working environment for rail depot personnel. It provides audible and visual warnings of train movements, which can be controlled efficiently by staff with higher levels of authorization from its road end panels.
