Zonegreen Limited products

Zonegreen’s Depot Personnel Protection System offers fundamental advantages to conventional  control systems, in particular, reliability, flexibility, expandability and resilience to single point of failure. Zonegreen’s Depot Personnel Protection System, commonly known as DPPS™, changes fundamentally the way in which the safety of rail depot personnel is achieved and demonstrated. Designed to provide the safest and most efficient method of controlling depot train movements, critical in today’s modern maintenance facilities. An established market leading product, Zonegreen’s SMART DPPS™ is now installed in the vast majority of UK train care depots and at depots worldwide.

Zonegreen’s Depot Manager SCADA software provides a graphical overview of the status of the SMART DPPS, which displays key information to make operations quicker and easier to implement, ensures safety systems are used at all times and offers comprehensive traceability of operations in the depot.

Designed to increase railway depot and workshop safety, the Zonegreen Points Converter allows the automation and remote operation of manual hand points, switches and rail road crossings.

In and around traincare depots, where a momentary lapse of concentration or small error of judgement can have dire consequences, properly engineered solutions can play a major part in protecting personnel and equipment. Engineers at Zonegreen have applied the concept of interlocking, long familiar in the rail industry, to create increasingly sophisticated systems with the potential to prevent personal injury or costly damage. These interlocks are key to high-tech systems and can prevent unauthorised train movements or other actions initiated by personnel who have not followed the stipulated safety procedures or precautions.
