Papakura to Pukekohe electrification
South Auckland, in particular Papakura through to Pukekohe, is expected to become home to an additional 120,000 people and provide another 38,000 jobs during the next three decades. Electrifying the network in this area will enable residents to be able to get around the region more easily on public transport.
At the moment only diesel trains (or DMUs) can operate on the 19km section between Papakura and Pukekohe, so passengers from south of Papakura must switch trains to get to and from the city. Electrification of the line means electric trains (EMUs) can travel through to Pukekohe.
Once complete there will be better commuter services between Pukekohe and the rest of Auckland, making rail a more attractive travel choice for those living or working in the area.
Funding of $371 million for this was received as part of the Government’s New Zealand Upgrade Programme.
New overhead masts will be built along 19km of track between Papakura and Pukekohe to power electric trains for commuters
Preparatory work on the project began late in 2020. Work includes:
Extending the overhead power system from Papakura to Pukekohe
Masts carrying overhead wires to power the trains will be built alongside the tracks on existing rail land. These will be very similar in design to those already in place north of Papakura.
A new power line will be built from Transpower’s Drury substation to join the rail network so there is electricity for the trains.
Existing track and signaling upgrades
New signaling will be installed to improve safety and ensure compatibility with the new overhead power system.
Track changes include layout improvements in key areas to allow more flexible train movements and we'll be lowering the tracks beneath Stadium Drive and SH1 overbridges to create enough room for the wires.
Redeveloping Pukekohe station to allow for more services and longer trains
KiwiRail is working closely with Auckland Transport to support its redevelopment plans around Pukekohe station. This will include improved passenger facilities (platforms and access).
We are also improving track to separate freight and passenger services, and as part of this will develop a new stabling facility for EMUs.
Future proofing the network
We are also working closely with the key stakeholders to enable three new future stations along the route and all works will be future proofed to allow for additional lines. These plans are being developed by the Southern Growth Alliance.
