Downer Engineering completed the design, supply, and installation of 70 km of fibre optic cable along Auckland's rail corridors for Auckland Regional Transport Networks Limited (ARTNL). The $8 million project involved installing two telecommunication ducts along the rail lines between several Auckland cities and towns using trenching, directional drilling, and rock cutting. Downer installed over 200 pits and fiber optic cables to form a network that now supports increased public rail services in Auckland through communications for safety, security, and train signaling.

ARTNL Railway Fibre Auckland Client: Auckland Regional Transport Networks Limited (ARTNL) Location Auckland Rail Corridor Type of Service Installation of 70 kms of fibre optic cable along the Auckland Rail Corridors Scope of Services Downer Engineering's service include: Site Preparation Civil Construction Fibre Lay & Joint Fibre testing Project Management As Built Documentation Health & Safety Overview Downer Engineering recently completed the design, supply and installation of fibre optic cables and ducting network for ARTNL. The project included the installation of a fibre optic network along the Auckland rail corridors between Papakura, Westfield, Auckland, Glen Innes, and New Market. The work involved the installation of two telecommunications ducts each approx 70 kilometres in length, 6 metres from the track centre-line and at a depth of 1 metre. Work also included installing ducts across bridges and through tunnels. A mix of trenching and directional drilling methods were used for most of the route with a rock saw employed to cut through 6kms of volcanic terrain. Downer installed 233 pits along the route through which Downer also installed and jointed 2 fibre optic cables (144 & 48 core). The network now forms part of the Auckland rail station facilities upgrade and is carrying information critical for public safety, station security and train signalling, all of which are were critical to supporting the increased frequency of passenger rail services throughout the Auckland area. The project took 18 months to complete and has a total value of $8 million.
