Light rail in Auckland


, New Zealand's largest city, is considering introducing light rail lines to replace some of its most heavily used bus routes. Many of these new light rail lines, if built, would run on routes used by Auckland's former tram system.

History

Background

was served by a network of traditional tramcar routes with horse-drawn trams and electric trams. The original tram network was in length at its fullest extent from the mid 1930s until closures began in 1949.

Initial proposal

In 2015, Steve Hawkins, Auckland Transport's Chief Engineer, said that the bus routes on Symonds Street and Fanshawe Street require as many as 150 buses each. The light rail study is considering replacing the bus routes on Dominion Road, Manukau Road, Mt Eden Road, Symonds Street and Queen St with light rail routes. All of those bus routes replaced routes on Auckland's former tram network.
Stuff.co.nz quoted Auckland Transport officials who described how the study was considering the option of building light rail routes with dedicated right of way versus routes where rail vehicles shared the road with other vehicles, as with a traditional streetcar system. Officials projected that the maximum passenger capacity of a true light rail line would be 18,000 passengers per hour, while the maximum capacity of a system where vehicles shared the road with other vehicles would be limited to 12,000 passengers per hour. This compares with a bus on a shared path shifting 2,500 people and a bus on a priority path's 6,000 people an hour.
In 2015, then Auckland Mayor Len Brown pointed out that the city's ten-year plan did not include funding for building new light rail routes.
An eastward line from the airport to Botany Downs has also been proposed with a new interchange at Puhinui railway station, planned to be built in two stages, the first of which is said to be an early deliverable component of the Airport to Botany rapid transit line, planned to be operational by end of 2020 /early 2021. This encompasses a new at-grade bus/rail interchange and enhanced station. Buses will still use the existing local road to cross the railway line to/from Manukau, along with local traffic.The second phase provides a rapid transit overbridge across the railway line to provide a more direct and bespoke rapid transit connection. The new rapid transit link will integrate with the new interchange station on the overbridge. The first stage is estimated to cost $59 million to construct. The line will also go through Manukau railway station before ending in Botany.

Detailed planning and funding

On 26 April 2018, Mayor Phil Goff and Transport Minister Phil Twyford announced the Auckland Transport Alignment Project 2018 with $NZ28 billion of investment in Auckland transport infrastructure over ten years, including the fast-tracking of light rail to Auckland International Airport.
On 9 May 2018, in a pre-Budget announcement, Twyford and Finance Minister Grant Robertson made the surprise announcement that work on two routes would commence immediately, with an open-tender process for funding, construction, and operation of the lines:
In May 2018, it was announced that the New Zealand Superannuation Fund had expressed an interest in financing, designing, building and operating Auckland's light rail network, in a consortium with CDPQ Infra, a Canadian infrastructure company. The consortium was named NZ Infra.
By early 2019, the cost of the two lines had been estimated at $6 billion, with an underground alignment through Queen St under consideration.

Replacement light metro proposal

In August 2019, Mayor Phil Goff announced that work on the light rail network may begin the following year. The same month, two delivery partners for the project were shortlisted; NZ Infra and NZTA, but it was stated that a 2020 start date would be unlikely. By late 2019, two different types of technology were being considered by the New Zealand Ministry of Transport. The original proposal from the New Zealand Transport Agency consisted of surface level light rail; the other from NZ Super Fund explored fully grade-separated, driverless light metro technology, with an underground alignment through Queen St and elevated sections elsewhere, with fewer stations between the city centre and airport.
In May 2020, it was reported that the light rail project had been placed on hold due to the impact of the COVID-19 pandemic in New Zealand. In June, Twyford confirmed that the Ministry of Transport was still committed to the project, but as a fully grade-separated light metro line between the city and airport; stating that "Our policy is that light metro is the form of rapid transit that Auckland needs. We've decided very clearly that we need a rapid transit system that's not competing with pedestrians and other cars in the road corridor. A light metro system just like you see in London, New York, Tokyo, Paris, is actually faster and more efficient. It would allow you to get from Queen St to the Airport in 30 minutes as opposed to the 47 minutes that was projected for the old streetcar model Auckland Transport developed." The Ministry did not release the updated cost of the new light metro proposal, or any time frame for its construction. However industry commentators have estimated the decision to use the metro mode will increase cost of the two lines from $6 billion to more than $20 billion, with a new design and construction period of 8 to 10 years beginning from 2021 at the earliest.
