Around a month ago Auckland Transport gave a presentation to the Campaign for Better Transport on their Light Rail plans. I wasn’t there however I was provided with a copy of the presentation and it contains some new information not shown before – and not all about light rail.
As a reminder of the background, AT say that even with all the improvements planned – including the CRL – the number of buses on many city centre corridors will need to be greatly increased however many of those routes are already at, or near capacity in terms of actual bus numbers. To handle the number of buses (including double deckers) they will need significant extra land for more bus lanes and infrastructure to handle the number of buses that would be required, an example would be at Wynyard where a lot of buses would need to turn around. The map below shows the bus routes through the city with the new network. Most of those bus lines will be running in the peak at least every 15 minutes with some routes such as Dominion Rd much higher resulting in over 180 buses an hour on Symonds and Wellesley Streets.
By 2046 the number of buses needed would be around double the desired capacity of bus lanes and as such buses will likely be very unreliable. Improved PT speed and reliability has been a big part in the fact that now around 50% of all people arriving in the city centre in the morning peak do so on PT. Some of the improved reliability is highlighted in these two charts showing the variability of travel times by mode at different times of the day. As you can see roads suffer from wide variability while the Northern Busway and rail lines – which have accounted for most of the PT growth to the city over the last 15 years – have fairly reliable times. The Panmure result will partly explain why patronage has grown at that station by a massive 71% in the last year.
AT say they’ve looked at a number of options and that Light Rail on the southern isthmus routes – which are some of the busiest bus routes in Auckland – allows them to significantly reduce the number of buses in the city which will be critical in achieving goals such as making the city centre more people friendly. That would change the map above to what you see below. Some parts of Symonds St would go from 180 buses an hour down to just 16 Light Rail vehicles. This is because AT are looking at large 66m long light rail vehicles capable of carrying 450 people each. Interestingly the map below also seems to suggest light rail across the viaduct whereas previous versions had it going via Fanshawe St. I remember a few board meetings ago an item in the closed session was titled LRT Fanshawe/Customs St Alignment so presumably a lot more work is happening in this area.
The presentation also included a number of new images along with some we’ve already seen. The new ones suggest some other significant aspects to the proposal. We know that stage one is to effectively replace the current City Link bus by getting light rail to Ian McKinnon Dr where there would be an initial depot. That was highlighted back in June within this document which AT have now published is now online. The presentation gives this as a view of what the depot which I assume this is on the patch of land between Ian McKinnon Dr and the motorway. I’m not sure where the NW Cycleway connects through here – let’s hope AT don’t forget that in their planning.
Just around the corner they show that at least in that section they haven’t forgotten the cycleway as part of very multi-modal street.
Where things get even more interesting is just a bit further north. The image below shows the intersection of Queen St and K Rd.
You may notice there is an absence of tracks and some odd things on the side of the road. That’s because it appears Auckland Transport are planning on sending light rail tracks through an underpass which is probably about easing the steep grade coming up Queen St. You can see the underpass emerging in this next image.
From there light rail would carry on down Queen St like in the images we’ve seen so far. Below are a few more images showing light rail past the front of Britomart, on Quay St and Lower Hobson St.
Lastly this next image shows what Fanshawe St could look like – obviously from a different version of the plan to the earlier map. It shows light rail in on a dedicated route on the northern side of the road. If it was installed on Fanshawe St I presume it would share that with buses from the North Shore that travel to Britomart.
Overall some interesting aspects, especially around K Rd. The last information about the project was that AT was looking to appoint a technical adviser to support further investigation of light rail. Of course there’s also the matter of how exactly it will be paid for which AT remain quiet about.
