Zonegreen delivers high levels of depot safety in Doha

The city of Doha

Zonegreen’s depot protection technology has drastically increased the safety levels for staff working on Qatar’s state-of-the-art driverless metro in Doha.

The Sheffield-based rail safety specialists have been commissioned to install their Depot Personnel Protection System (DPPS™) at the network’s three maintenance facilities.

The company is working with turnkey solution providers, Design and Projects International, on the new build installations, having previously collaborated on the Dubai Metro. Work on the Al Wakra Heavy Maintenance Depot, began in 2017 and was recently completed. Phases two and three are expected to begin in 2019 and finish in time for the system to open to the public in 2020.

DPPS has been installed across three maintenance buildings at Al Wakra, protecting a total of 18 road ends. Its decentralised control of safety mechanisms allows staff to isolate specific areas in which they wish to work, without disabling the entire depot. The system is also interlocked with the signalling interface, wheel lathe and bogie exchange equipment to prevent vehicle movements on roads where personnel are logged on or machinery is in use.

Christian Fletcher, Zonegreen’s Technical Director, said: “Fully automated systems offer a plethora of advantages, but come with a whole new set of challenges, not least the hugely complex infrastructure required to retain safety levels. Our technology gives depots complete confidence that people and equipment are protected from danger at all times, whilst improving efficiency by enabling workers with higher level access to authorise vehicle movements with their datakeys, removing the need for multiple stop starts.”
