Zonegreen Develops Smarter Depot Personnel Protection System

Sheffield-based Zonegreen has launched a new version of its flagship rail depot safety system, in response to increasing interest from clients across the globe.

Zonegreen has unveiled the new generation SMART Depot Personnel Protection System (DPPSTM), following its first complete overhaul in 15 years.

SMART Depot Personnel Protection System

Designed with export in mind, DPPSTM now uses intuitive functionality, based on a simple four-button controller and a graphical interface that can be programmed in any language, accommodating characters and letters. Remote configuration and assistance also makes overseas installations simpler and more cost-effective.

A wealth of extra features has been added to this latest version of DPPSTM, which has been under development for six years and cost many hundreds of thousands of pounds to bring to market. The system has always been the safest method of controlling train movements in depots, but it is now easier to use and even more efficient to run.

DPPSTM is specified in most modern maintenance facility designs in the UK and its reputation is growing quickly, having been installed in some of the largest and most sophisticated depots in the world.

Rail Depot Safety SystemIt combines powered derailers, road end control panels, train detection equipment, warning signals and personal datakeys to protect staff and infrastructure; it is the most advanced, reliable and tested product of its type. In addition, DPPSTM can be interlocked with a depot’s signalling system, removing the need for shunt signals and allowing more streamlined processes to be implemented.

The powered derailer used by DPPSTM is the only one approved by Network Rail at present. During its development, Zonegreen underwent a testing programme in its advanced research workshop that simulated five years of continuous use, to ensure total reliability. This cutting-edge, essential piece of equipment offers absolute safety to depot staff, preventing them from injury caused by moving trains.

The customer-centric focus of the next generation DPPSTM extends to its design, which is more ergonomic than its predecessor. A tactile membrane has been added to improve durability, along with high-quality electronic components that have increased its reliability and reduced power consumption, delivering further cost savings.

By continuing to utilise distributed intelligent technologies, Zonegreen has also ensured that if an error is detected on one road, normal operation can continue throughout the rest of the depot. This minimises disruption to workshop activities and represents a significant step forward from traditional centralised control panels.

Off the shelf software is now used to run DPPSTM, which means the system can still be configured to the unique layout of each facility, yet enables depots to benefit from years of development, mitigating the risk of errors and reducing the risk of bugs. It is also now easier for Zonegreen to share new features and updates with existing and future clients.

The datakeys used to operate DPPSTM have also undergone a facelift. Most notably, they have changed in appearance, whilst internally the electronic memory chips have been upgraded. Following feedback from depots about their standard processes, the key now allows for an increased number of authorisation levels to be granted, improving encryption and security.

Christian Fletcher, Zonegreen’s technical director, said:

“We are very proud of the next generation DPPSTM. In the 15 years since it was launched, we have come a long way in terms of the technology available to us and the capacity of our team. Throughout the research and development phase, we listened to the needs of clients at home and abroad and used their feedback to create a system that is now simpler to install, easier to operate and more efficient to run.”

Rail Depot Personnel Safety

Zonegreen are by far the market leader in the provision of rail depot personnel safety, specialising in the delivery of intelligent technologies to offer protection from dangerous environments in a safe and efficient manner. An unrivalled reputation for quality, safety and reliability has been built by the Sheffield based safety specialists. The team of expert engineers at Zonegreen have achieved this reputation by developing an impressive range of intelligent technologies to offer safety related products and innovative planning of train maintenance operations. Continued research and development projects have ensured that Zonegreen longevity and reputation as a global leader in depot safety systems. Whilst the companies enduring success is predominantly credited to its Depot Personnel Protection System (DPPSTM), the firm has also brought a successful range of complimentary products to market, including interlocking solutions, Points Converters, railway maintenance planning applications and out-of-gauge warning systems. These systems are installed worldwide and can be used in sectors as diverse as transport, petrochemicals and aerospace. [gallery ids="11771,11773,11774"]

Depot Personnel Protection System (DPPSTM)

The Depot Personnel Protection System, Zonegreen’s flagship system, that is specialised and designed to ensure the safe and controlled movement of rail vehicles into and out of depots, so that maintenance operations can be conducted without endangering staff or the depot infrastructure, has recently undergone a complete overhaul. A wealth of additional features have been added to this latest version of DPPSTM, which has been under development for six years and cost many thousands of pounds to bring to market. Zonegreen's SMART DPPS™ is highly advanced, state-of-the-art and incorporates intelligent, distributed communication technology, as well as electronic personnel datakeys to uniquely identify staff working in different safety zones. The Zonegreen's SMART DPPS™ allows the user to: Additionally, Zonegreen depot manager software provides an overview of the status of the DPPS™ and personnel logged on.

Points Converter for Powering Manual Points

The Zonegreen Points Converter allows the automation and remote operation of manual hand point switches and rail road crossings, increasing railway depot and workshop safety. Benefits of powering your manual points The Zonegreen Points Converter system comprises two parts:

Train Maintenance Planner

The planning of train maintenance operations is still commonly conducted on whiteboards located in operation control rooms, detailing which train units require servicing, maintenance tasks, as well as expected arrival and departure times. These are updated manually either in a tabular form or on top of a graphical layout representing a bird's eye view of the depot. Zonegreen's operator planning suite, as a multi-user, web-based graphical task planning application, is a cost-effective replacement of the whiteboard. It consists of two main views: a graphical layout representing the depot on which users can position trains and create and assign maintenance tasks, and a tabular layout to plan trains' scheduled arrivals and departures. The train maintenance planner function of the depot manager allows staff to:

Safety Interlocking Systems

The concept of interlocking has been applied to create increasingly sophisticated systems with the potential to prevent personal injury or costly damage. Our engineers have developed highly sophisticated safety interlocking systems in train depots that prevent unauthorised movements of trains, thus protecting injury or death to personnel and damage to other trains and equipment in the depot. Additionally, we manufacture internal interlocking systems that prevent danger when personnel try to circumvent safety measures. This, in turn, reduces the risk of damage to equipment. Zonegreen has developed a safe system of work that absolutely prevents access to high level access platforms by means of a fully guarded stairway and interlocked gate that can only be opened with a key that is released from a control panel when the OLE is locked and earthed. The sequence of unlocking and removing keys that, in turn, allow other keys to be released, ensures prohibition of access to areas unless they are safely isolated and earthed. This interlocking system is vastly superior to a ‘permit to work’ system that is only reliable provided that everyone in the loop strictly obeys the rules.  It is also possible to interlock third party equipment.
