One of the proposals that is floating around at the moment and something that is being pushed fairly strongly by the Maungakiekie-Tāmaki Local Board is the idea of a transit oriented development (TOD) at Tamaki centred around the re-opening of the Tamaki train station. This was also highlighted in the CCFAS supporting documents looking at large scale development that is being planned along the rail corridors. At first the idea makes some sense as the area is both fairly close to town thanks to the train line and is an old industrial area that has large lots and that is ripe for redevelopment. The map below shows the area that is being talked about for a TOD. The council/AT own the land in red due to the AMETI plans while the light orange is one single land holding.
But while I like putting more people right next to the rail line, I think there is a major flaw with the idea an it is to do with the idea of reopening the Tamaki train station which is intended to be right in the centre of the development. The issue is its proximity to the two stations that would surround it, Panmure and Glen Innes as it would only be around 800m and 1.2km away respectively (to/from roughly the centre of the platforms. That may seem like a lot but for a rail system it is pretty close and means the trains start to lose some one of their big advantages over buses which is their speed. It means that the distances between stations in this section end up similar like the horribly slow inner western line stations and by my calculations such a station could slow down trains by as much 1½ minutes. That would affect anyone who used the trains from south of the station and while it might not sound like much, making savings of that level across a large number of people is what is often used to justify large transport projects like motorways. In effect there would have to be massive amounts of additional patronage to justify the addition of a station here.
So what are the alternatives, well most people generally tend to be ok walking up to ~800m if it means access to a really high quality PT option like a train station with frequent services and 800m from the northern end of Panmure is right smack in the middle of this proposed development. Further it would be a nice flat walk taking most people somewhere between 5 and 10 minutes depending on how fast they walked. Those with a bike could go even faster and cycle the journey to Panmure in just a couple of minutes, even at a leisurely pace and by my reading of the AMETI plans, dedicated cycle lanes are going in alongside the rail line/ new AMETI road.
Perhaps the only redeeming feature is that it would also be the closest station for those living in Stonefields or in the older housing developments to the east of the area but even then most would probably still find it just as easy to get to either Panmure of Glen Innes as they would getting to this station. Building the station could also have other unforeseen consequences, in particular the neighbouring Orakei local board have been pushing to get another station added between Glen Innes and Meadowbank. AT have already dismissed that as being to costly with not enough patronage however this development could see them reignite that debate adding more political pressure on to AT. I think looking at the plans so far, it simply doesn’t seem worth it to put a station in here as the existing ones in the area already serve the potential development fairly well.
