Zonegreen’s Depot Personnel Protection System (DPPS™), commonly known as Depot Protection System, changes fundamentally the way in which the safety of rail depot personnel is achieved and demonstrated. Based on distributed intelligence control architecture, it offers fundamental advantages to conventional / bespoke PLC (progrommable control logic) based control systems. The reliability, flexibility, expandability and resilence to single point of failure of the DPPS™ are part of what confirms the system as the market leader.

As a safety-critical system that demands high system integrity, Zonegreen’s Depot Protection System has demonstrated its reliability and capability with its numerous installations in UK traincare depots, as well as internationally in Ireland, Dubai, Australia and New Zealand.

The credibility of the Depot Protection System has been proven yet again when it attained a SIL 1 accreditation for the installation in the prestigious Eurostar Temple Mills Engineering Depot in East London. The system is compliant with IEC61508 and EN50128/50129

The system, installed throughout the UK and across the world, allows the safe and efficient control of train movements within depots – crucial in today’s busy working environments – protecting both staff and infrastructure. The system’s features include powered derailers, road end control panels, personal datakeys, train detection equipment and warning beacons and klaxons, integrated through an intelligent distributed control network. Furthermore, the company’s Depot Manager software offers a complete overview and full traceability of the system’s use.

The video above shows Zonegreen’s Depot Personnel Protection System installed in the Eurostar Temple Mills Depot. It demonstrates the various interfaces and interlocks with other equipment in the facility, for instance, the signalling system, overhead live equipment (OLE), overhead gantries and bogie drop system, to ensure staff working in the facilities are protected from unauthorised train movement.
