Zonegreen  designed and manufactured the Depot Personnel Protection System DPPS for the new Eurostar depot at Temple Mills, East London, which opened in November 2007. The company believes this to be the most advanced DPPS system installed in the UK.

“It was an essential requirement for this international project that the DPPS for Temple Mills would comply with EU safety standard SIL1 (Safety Integrity Level)”, Zonegreen engineer Richard Eason points out. “The Depot Personnel Protection system was independently assessed and approved for this purpose by Lloyd’s Register Rail. We also designed the DPPS to integrate successfully with the refined signalling system at Temple Mills.”
