Mayor Len Brown can take a bow. Others may have helped turn the Government around on the rail loop - possibly Lester Levy, chairman of Auckland Transport, or Michael Barnett of the Chamber of Commerce, where the decision will be formally announced tomorrow - but the Mayor deserves most of the credit. He made the project his own and promoted it doggedly against those who doubt that rail can be the answer to Auckland's congestion.
The doubters have included every government, National and Labour, of the past 40 years. The historical significance of the decision can hardly be overstated. Many tomorrow will invoke the memory of Sir Dove-Myer Robinson, whose campaign for a railway with an underground city loop started in the 1960s. The project was the central element of Auckland's first urban plan, produced by the Auckland Regional Authority as long ago as 1969.
But this is not the first time the dream has seemed on the verge of success. In 1973 the Kirk Government agreed to provide electrified tracks and an underground loop - and the ARA, at Robbie's behest, rejected it. Those elements were not sufficient, he said, to produce "rapid rail". Speed was essential to attracting enough patronage to make the scheme affordable for Auckland.
The term "rapid rail" eventually disappeared from plans, replaced by light rail when trams were back in vogue and now by "integrated rail", which means fed by bus services. Whatever it was called, governments remained fearful of the cost and unconvinced that fixed rail routes were suited to Auckland's urban form.
The cost, estimated at $2.8 billion, is a fearsome amount for a short link from Britomart to Mt Eden. Former Transport Minister Steven Joyce argued it would leave little in the kitty for any other projects in the Auckland region over the same period. It is hard to see what has altered that assessment.
