Depot Protection
SMART DPPS™ (Depot Personnel Protection System)
Depot Personnel Protection System, commonly referred to as Depot Protection System, protects staff and equipment by ensuring the safe and controlled movement of rail vehicles into and out of depots. This allows train maintenance operations to be conducted without endangering the safety of staff, and damaging other maintenance equipment in the depot.
Zonegreen's SMART Depot Personnel Protection System (DPPS™) is a highly advanced, state-of-the-art protection system incorporating the use of intelligent distributed control and communication technology, as well as electronic personnel datakeys to identify staff working in different safety zones.
The Depot Personnel Protection System is fully programmable and can be set up to the precise requirements of the depot. It is pre-configured to function with other Zonegreen equipment, but can be modified for connection to third party products.

Your Depot Personnel Protection System will include all or some of the following functions:
Road End Panels
Road end panels (REP) are networked together and constitute the operator consoles of the Depot Personnel Protection System. Located at the end of each road, usually adjacent to the track entrance, the REP manages all depot protection functions for that road. Personnel are issued with a unique personnal electronic datakey to log on and off a work area via the REP’s input terminal.
Datakeys: All depot personnel have a datakey, which replaces the traditional personal padlock in old safety systems. It is set up with the user’s personal information and their authorisation level – depot staff, supervisor or engineer – and can be extended to include areas such as door control.
Derailers c/w Shunt Signals
Shunt Signal: Signals are located at the entrance and exit of the workshop to indicate to the driver whether it is safe to proceed. Inbound signals are mounted on low level galvanised stands, whilst outbound signals are placed at cab height on galvanised stands or stand off brackets.
Derailer
A derailer may be manually or electrically powered. They are the ultimate safeguard in preventing vehicle access and are fitted to tracks approaching the depot.
Treadle/Track Switches: Switches are fitted to the tracks approaching the depot to warn operatives of a vehicle’s approach. They are triggered by the passing wheel and can be used to indicate that a vehicle is waiting. Zonegreen has developed its own track switches, which are sealed for life and maintenance-free.
Audio Visual Warnings: Beacon signal lamps and klaxons are installed above each track within the depot and within the pit and are used to display the status of the protection system. Zonegreen provides any beacon lamp combination and additional lamps can be fitted to show the status of an overhead line.
