Metro operates 210 six carriage trains across 869 kilometres of track throughout Melbourne. During a review of a 15km underground rail network that connects four stations in the Melbourne CBD, it was agreed that the emergency lighting technology installed along these tunnel networks were out of date, triggering a need to look at more current technologies in relation to testing capability, lighting performance, maintenance and safety in the event of an evacuation being required. Metro worked alongside ARUP engineers to specify the required performance and placed the tender into the market for manufacturers to present solutions.
Project Completed 2015
Clevertronics, along with two other emergency lighting companies placed a bid for the project, however, only Clevertronics was able to provide a comprehension solution to meet all of the specifications, quality, installation and logistical challenges.
The Clevertronics solution, proposed and accepted by Metro was based on the L10 Nanophosphate range, which met the required lighting and emergency lighting performance and also
minimised the need for any large scale maintenance for at least a decade. The trademark L10 Nanophosphate product features a world first: Lithium Iron Nanophosphate battery. The patented chemistry of L10 batteries are proven to provide three or four times the life of economy Nickel Cadmium or Nickel Metal Hydride batteries and 50% longer battery life compared to any other Lithium product on the market. Further, the light fittings were networked via the electrical power line, the existing telephone cable infrastructure and Metro Trains’ LAN/WAN ICT network in order to automatically perform and diagnose results from the six-monthly testing regime under the Australian standard AS2292. This was achieved with the Zoneworks XT monitored emergency lighting solution.
Finally, the light source was comprised of the optically engineered weatherproof POD, two of which were fixed to an IP67 housing at various positions to induce vertically downward light. The housing was in turn fixed to a metal strut frame so that the complete unit would be easily installed and removed from the tunnel surface. The light source is provided via twin LEDs in each POD to meet the minimum amount of light in both normal lighting conditions and in emergency mode.
