An interesting article in yesterday’s Herald, outlining the results of a poll into transport in Auckland:

An UMR Research poll, the results of which are out today, found 79 per cent of 241 Aucklanders in favour of installing railway lines across the harbour – whether on a new bridge or through tunnels – and 18 per cent against.

They were more evenly split over the form of a new harbour crossing, with 38 per cent opting for a second bridge and 41 per cent for tunnels.

Twelve per cent did not want any new crossing.

241 is not a huge sample, although the large majority of people wanting a rail link fell well outside any margin of error. It would have been interesting to ask people whether they preferred another road crossing or for an additional crossing to be rail only (assuming that we can’t afford both).

The article continues:

But the Campaign for Better Transport and the Forum for Auckland Sustainable Transport say rail tunnels would be far more cost-effective than a new motorway link, and would remove capacity pressure from the existing bridge by taking buses off it and encouraging more people to leave their cars at home.

Campaign convenor Cameron Pitches said it was ironic that almost 80 per cent of Aucklanders favoured a rail link, as that was about the same proportion as the Government said drove cars to work and should therefore receive most transport funding, despite growing concern about rising oil prices.

Forum spokesman Bevan Woodward said: “We find it extraordinary that the Government would seriously consider a road-only bridge to solve Auckland’s future transport issues.”

Mr Brown said the poll result reflected feedback he received every day from Aucklanders about rail projects including links to North Shore and the airport, and a central city tunnel.

“Aucklanders understand that we need to unclog our roads by fixing public transport – we need to future-proof the additional harbour crossing for rail to cater for Auckland’s growth.”

While I still have many doubts about the timing of a rail crossing to the North Shore (let alone a road crossing), it does seem as though the rail link is very popular.

Unsurprisingly, Steven Joyce is not so keen:

But Transport Minister Steven Joyce said the trouble with such polls was options were presented as costless, and he had received a rough estimate of $3 billion for a rail crossing from Gaunt St in the Wynyard Quarter to Takapuna.

Officials believed it could cost another $6 billion to $7 billion to run rail tracks to Albany, because of a need for more tunnelling, given that the busway corridor would be unsuitable for trains.

They had also told him that commuter rail for the North Shore would entail huge extra spending south of the harbour, for new underground stations.

“A lot of things sound like good ideas when we have no idea how much they will cost us, whether they be through taxes, big hikes in rates, or more likely both.”

I have a couple of issues with what Joyce says here. Firstly, it seems strange that he’s worried about spending $3 billion on a rail connection but not concerned about spending nearly twice that on a road bridge or tunnel. The second is that the cost estimates for a full North Shore Line are complete rubbish: based on a completely over-the-top costing of the train stations plus a stupid route.

In the long run I seriously think that investing in rail is the cheaper option – compared to all the motorway building and widening (plus the huge environmental effects) associated with a second road-based harbour crossing. Steven Joyce tries to style himself as being ‘sensible’ when it comes to transport policies (supposedly in comparison to the non-sensible Len Brown I guess), but when you actually look at the huge cost of many of these motorway projects that image starts to wear thin very quickly indeed.

  1. The problem is that the media buy it. No one has questioned the NZTA report. Anyone can see that they’ve taken the most expensive route possible and then gold plated it. A quick peer review would quickly show that report to be complete rubbish. I can’t see how a tunnel that is shorter and has less stations would cost more than the CBD rail tunnel. A rough estimate that it would cost $3 billion is BS. I wonder if he got that from his barber.

    Why do they keep using this strawman?
    Rubber tyred metro systems and things like Vancouver Skytrain might negate the need to do so much digging. Vancouver’s Skytrain has short stations that can fit into busway platforms, it can take curves well.
    Rubber tyre metro systems can take gradients of up to 12%, a normal train on steel wheels might only be capable of 2%.

    1. This would make linking services with the existing system very complicated, i.e. no service could be run from the Shore out South for instance, a rubber-tyred metro has never been suggested and wouldn’t make much sense in Auckland.

  3. $ 7 Billion for trains to Albany. Are they using platinum rail and diamond encrusted carriages for service?

    Brisbane’s Cross River Rail tunnel is costed at $8.5 billion and includes 9km of tunnel. I don’t think much tunnel is needed for North Shore.

    1. If you look at the route you’ll see that they costed each station as $307 million and have more or less costed a full tunnel the entire length out to Albandy i.e. around 16kms or so. Ironically, in that sense it would appear that the Brisbane tunnel is the one that’s gold plated.

  4. The difference is a road link could possibly pay for itself (although the bridge really doesn’t have that much of a capacity problem, the issue is replacement). A rail link couldn’t even start to do so. You could ask North Shore residents to pay $10,000 a head (today’s values) for a rail link through rates increases recovered over a 20 year period ($500 + CPI) and see how popular that would be.

    However it is clear it wouldn’t be popular if users had to face the costs of the infrastructure they use.

    1. The comparison is the cheapest bridge option vs the most expensive tunnel option. Hardly a fair fight – and deliberately so it would seem. Choose the best bridge option and the best rail option and the numbers are a lot closer.

      The rail tunnel option will always be more expensive, but an approach on strict $$ terms is knowing the cost of everything, but the value of nothing. Something Steven Joyce is a master at.

      What “price” do you put on a bridge that will destroy the current setting that is the harbour? I hate to get all touchy-feely but a new bridge right alongside the existing one, looking different, having a different height and gradient will look utterly ridiculous and become an eyesore.

      I cannot believe it is even being considered without demolishing the existing one, and that’s not going to happen.

      Yes, tunnels with might be more expensive. But there is a bigger picture here, surely…..

      Would Sydney drop the ANZAC bridge right next door to the existing one?
