The group pushing for an overhead version of the CRL have cropped up again. Yesterday they published a letter and presentation that they have sent to both Len Brown and Gerry Brownlee and a few others with their alternative. They are now calling their proposal eLtrack.
eLtrack – an elevated alternative for the CRL Tunnel.
We are a group of Auckland-based infrastructure consultants. Over the last year we have prepared a contemporary and affordable alternative for the proposed CRL Tunnel.
Our proposal, which we’ve called eLtrack, is a mostly elevated train route above existing transport routes. It provides a range of benefits for the city when compared to the tunnel proposal, not least of which is a significantly lower cost.
The eLtrack route is double-tracked and meets the specifications for the new EMUs. We have completed an assessment for the route and taken account of relevant transport, engineering, urban design, and planning matters. An ‘order of magnitude’ cost estimate is also available.
The project is explained in the attached brochure. The Light Rail Transit component along Queen Street and Karangahape Road is essential to the idea, and is included in the estimated cost.
eLtrack was presented to the Office of the Mayor, NZTA senior staff and senior personnel of the CRL team early last year, and was mentioned in the City Centre Future Access Study (November 2012). We are disappointed that it was not seriously considered in that report, and we believe its casual dismissal as a viable option was a mistake.
The advantages of eLtrack over the tunnel, additional to its savings of around $750M, are outlined in the brochure.
We have met with the MP for Auckland Central, Nikki Kaye who suggested we write to you with copies to key decision makers. We consider eLtrack needs a serious evaluation as an alternative to the tunnel. We recognise the extent of work that has already been done on the latter, and that an evaluation may still favour that option.
The group fully supports the concept of a City Rail Link, and does not seek to slow progress toward that end. However, given the scale of the project and the Government’s reluctance to contribute to its cost, we consider it prudent to have a viable and lower cost alternative for all parties to consider and compare.
We are prepared to meet with an evaluation team and table the information we have prepared. This includes track alignment diagrams, sketch cross-sections and the cost estimate.
We would appreciate the opportunity to present eLtrack to you personally, and to arrange a meeting with your evaluation team.
I don’t think that the image quite shows just how much impact they are proposing. The very reason the NZTA ended up building the Victoria Park Tunnel was because the local residents strongly fought to prevent another viaduct being built. Perhaps by proposing an even higher viaduct they think they the residents will be so shocked it would give them all coronary and therefore they won’t fight the proposal. In reality the visual impact is likely to be immense. From what I can tell, it appears the track would be approximately 10-15m above Fanshawe St, 10m above the Wellington St bridge and 10-15m above the Newton Rd bridge. As a comparison the Newmarket viaduct is up around 20m high.
But the visual impact isn’t the only issue with this proposal. By far the biggest issue is simply the catchment. The CRL travels right through the heart of the densest area of employment in the entire country. There are something like 80,000 jobs and 60,000 students within range of the CRL stations yet the focus of this proposal seems to be on getting a station at Wynyard, an area that is predicted to have somewhere in the range of 10,000-20,000 jobs. Why you would try and avoid the area that would provide the most benefit is a mystery. Here is a map showing a 400m walking catchment of the CRL stations (red) verses this proposal (blue).
Wynyard will also eventually be connected with a rail station when a line to the North Shore is built further diminishing this proposal compared to what is being planned.
Other issues include that the route is roughly 700m (20%) longer than that taken by the CRL, reducing the amount of benefit we would receive from faster journeys. They suggest that at $2.14 billion their proposal is $700m cheaper than the CRL however that seems to be comparing their propsal to the inflation adjusted price for the CRL. The actual price for the CRL is now down around $1.8b and could drop further as the project progresses. In a bid to save even more money they suggest building the eLtrack as only a single line initially. For some reason the proponents also seem to want to prevent any buses from actually getting into the CBD and have indicated that all bus routes will terminate at the outskirts of the CBD and transfer to either the rail network or an at grade, tram line that runs from K Rd to Britomart.
All up the scheme seems to fail on almost every single level, it doesn’t save any money, it doesn’t save any time, it doesn’t go where most people want to go forcing a lot more transfers and it would have significant visual impacts to a large area of central Auckland. I can’t think of one redeeming aspect about it. As mentioned in the letter, it was even included as an option in the CCFAS but was dismissed for many of these reasons. I will leave the last word to this mention of it from the report.
The elevated rail was assessed to have some benefit with regards to City Centre access and is much cheaper than a light rail network. However, it is the worst performing option overall with significant implementation, environmental and amenity dis-benefits.
