Zonegreen have continued to build their relationship with Qatar rail, installing its flag ship Depot Personnel Protection System at two further depots for the Doha Metro.

The Al Rayyan depot consists of three maintenance buildings which will house 90 three car trains when the system is running at capacity. DPPS has been installed on 7 single ended roads; 4 of which are fitted with powered derailers providing physical protection for staff working in areas of potential risk.

The final depot to benefit from Zonegreen’s technology is the Ras Bu Abboud stabling yard that serves the metro’s Gold Line. This single road facility has been fitted with warning beacons and klaxons, to warn staff of vehicle movements.

In all three of Doha Metros depots, staff log on to DPPS via personalised datakeys that enable them to protect the areas in which they wish to work, without disabling the entire depot. Those with higher level access can also control vehicle movements with ease and efficiency at a fraction of the cost of a full signalling system.
