If Aucklanders look at the new study with scepticism, it would be understandable. Any system of tram lines along city roads would be a substantial investment and a major public works project. Innovations of this scale have been discussed, shelved or discarded over generations. The electrification of Auckland's rail lines and introduction of a new train fleet seems to have been creeping into action for longer than the Super City has been discussed. Even now, some old diesel trains are chugging away while Auckland waits.
The CRL, from Britomart up to Mt Eden, is still in doubt. If financing is eventually agreed, the tunnels will not be completed for an age.
Overlaying existing plans with another project, with not only extra cost but disruption to traffic and communities during construction, might seem all too much to contemplate for a city grinding into a new year.
Yet transport officials need to keep looking for answers. Overseas cities are lining up to improve their public transport with new light rail or trams which function without overhead lines or high voltage ground rails. As the technology improves it would be remiss of Auckland planners not to challenge their own past thinking on buses. Figures supplied by AT show designated tram lanes could carry 18,000 people an hour on the six main roads identified, compared with 6,000 on buses; if the tram lanes are on shared road space the total passenger number reduces but it is still far higher than buses on comparable lanes.
The agency has anticipated pushback on funding for tram rails and carriages with so much already on Auckland's infrastructure agenda. Its chairman, Dr Lester Levy, talks of a "novel form of financing" involving private investment.
If the study finds trams are compatible with cars on these big city roads, and will carry more people more quickly in a zone which will be untouched by the CRL's benefits, then the Auckland Council, Government and ratepayers must seriously consider them.
They are not the only solution to city congestion but they could well be one of the many Auckland needs to keep things moving.
