Working with contractors, Taylor Woodrow and depot operator, Abellio Greater Anglia, phase one of the project has been completed, fitting roads 16 and 17 with DPPS to eliminate the risk of injury associated with train movements. Interlocking solutions have also been installed to eliminate the risks of overhead lines.
DPPS combines powered derailers, road end panels and visual and audible warnings to protect personnel. The system is operated via electronic datakeys, with varying authorisation levels, that allow the user to create safe zones in which staff are working. It is linked to Zonegreen’s Depot Manager software that displays key information to make operations quicker and easier to implement and offers comprehensive traceability.
On roads 16 & 17 at Crown Point, Zonegreen has interlocked the gantry gates, preventing access to high-level areas until the overhead line has been isolated and earthed through a key operated panel. The fume extraction equipment and a crane on road 16 are also interfaced with both the OLE and DPPS, ensuring neither can be operated whilst the overhead line is live and inhibiting train movements until they are in a safe position.
