I keep a fairly close eye on many of the documents that come out of Auckland Transport and recently I’ve been noticing a change in some of them in regard to light rail.
When first announced last year AT proposed four light rail routes across the Isthmus to “fill the void” – the central isthmus area between the Western and Southern rail lines. Within the void are some of Auckland’s original tram suburbs and as such some of the city’s busiest bus routes. AT predict that at current levels of growth the streets in the city centre will soon become a wall of buses and so using higher capacity light rail on some busy routes would help in reducing overall volumes of vehicles on city streets. They proposed to light rail on Sandringham, Dominion, Mt Eden and Manukau roads. That would then free up more space for buses from other areas such as the Northwest and the North Shore.
At the time they produced this map showing how the light rail plans might fit in with their other plans for rapid transit across the region.
Those four routes would enter the city using either Queen St for the first two mentioned and Symonds St for the latter to. The timing was also be spread out over a few decades so it wasn’t going to happen all at once but they showed all the routes anyway.
The map above also shows light rail travelling via Quay St before going to Wynyard. Late last year the AT board agreed to go via Customs St instead. Given my experiences with buses through that area I think this is the right decision.
Later AT also started thinking about using light rail to the airport and that was added to the maps too. Four light rail lines can also clearly be seen in the staged Rapid Transit maps which AT have been showing around a lot lately.
But in recent times I’ve started noticing some changes in the way AT talk about light rail and it seems to coincide with the project getting more scrutiny from the likes of the NZTA and the Ministry of Transport.
A recent presentation to the council’s Development Committee had an updated version of one of the maps above. The presentation was talking about the next study/document to be created looking at the central city – known as the Central Access Plan. As part of that AT included a map showing the potential investment programme. As you can see only the Dominion Rd light rail corridor is shown properly although there is also a faint Sandringham Rd line too. Missing from the map are the Mt Eden and Manukau road routes.
Now a new version of the Rapid Transit map has been published by the herald and it too only shows two light rail corridors.
The Dominion Rd route makes a huge amount of sense as it is the busiest of the routes and while it may not look like it, the Unitary plan actually allows quite a bit of development pretty much all the way down the corridor through the use of mixed use zoning. But Sandringham Rd is also included too. My guess is the building the Dominion Rd route will also necessitate supporting infrastructure like depot’s which would be shared with the Sandringham Rd route and as such it likely means the cost of laying tracks down the road is much lower compared to doing so on the Mt Eden/Manukau roads routes.
So what about the other two routes?
The AT website now only lists these two routes mentioned above and does so with details such as the distance and number of stops for each section (Wynyard to Britomart, Queen Street to Dominion Road, Dominion Road and Sandringham Road). Now the only mention of the other routes is:
Wider light rail network
A wider light rail network could add 2 corridors along Mt Eden and Manukau Roads, converging on a second spine along Symonds Street.
This does seem suggest that AT have scaled back their thinking or plans for light rail and bumped Mt Eden and Manukau roads off the immediate agenda. This could be due to potential funding pressures or just more detailed investigations into the proposals but either way it would be good for them to say just why this has happened.
As an aside it’s good to see the Herald finally publishing a map showing the plans for the rapid transit network. It’s something they should have been doing a long time ago and if not them, AT should be pushing it a lot more including making it and the details behind it more accessible on their website. They and the council have also started showing how it develops over time rather than at one point in the future – just like we did with the Congestion Free Network which is great to see. Perhaps they should make an interactive version, something a bit like this.
