On Tuesday, Auckland Transport announced that ticket gates have gone live at Manurewa. That makes it the seventh station that have now has gates operating. It follows Britomart, Newmarket, Manukau, New Lynn, Henderson and Ōtāhuhu. Manurewa is also unique because it’s the first station gated that has side platforms without some sort of concourse area. Below are some images of the station with gates from ATs website
AT are also working on gating another five stations, Papatoetoe, Middlemore, Parnell, Papakura and Glen Innes.
I know a lot of people would like to see gates at every station, however that’s not cheap, often costing more than any fare evasion it might prevent. There are additional safety benefits from gated stations though and that will play a role in some of the stations listed above. Ensuring that most people pass through a gate on at one end of their journey can at least help with the fare evasion issue. AT say that after the additional five stations are complete, 90% of trips will pass through a fare gate.
It did get me thinking about a couple of questions.
- With Manurewa gates now live, what percentage of train users pass through a gate now?
- After the stations above, what would be the next station to gate to get the most trips to boost that 90% figure, and what does that push it to?
- How many train passengers will pass through a gate at both the beginning and end of their journey?
To help answer these questions I used the rail station data AT provided me for the last financial year (to end of June 2017). The data shows how many HOP trips went from each station to each other station. Obviously what it won’t do is pick up all the trips were people aren’t currently paying, although I’d expect few of those would convert to actual trips once gates go in.
Last year there were 19.6 million trips on the rail network and around 17.6 million of these were completed through HOP. The difference will mostly be trips where someone didn’t tag off or special event trips.
With Manurewa now live, what percentage of train users pass through a gate now?
I looked at all trips beginning or ending at a gated station. Given most trips from Manurewa were already to a gated station (e.g. Britomart), I only looked at the net increase it provided. With Manurewa that brings the number up to 81% of all trips.
Gating all stations that AT mention will bring that number to 89%, close enough to 90% for their marketing I guess.
What is the next station to gate to get the most trips to boost that 90% figure, and what does that push it to?
Using the same method as above, I looked to see what the next biggest station was with trips not already passing through a gated station. I wasn’t surprised to see that was Grafton. What did surprise me was that it added about twice the number of trips as next station, which was Sylvia Park. In fact it actually added more trips individually than any of the current batch of stations.
Gating Grafton would push the number of trips through a gated station up to 92%. I assume Grafton will have to be gated by the time the CRL opens. If for nothing else, for the same reason that Parnell is on the list, to prevent it being used as a loophole.
How many train passengers will pass through a gate at both the beginning and end of their journey?
As more stations get gated, the number of people who pass through gates at each end of their journey also increases. From just 5% of trips initially when it was just Britomart and Newmarket, with Manurewa that number is now at 17%. That number will almost double to 33% once the next 5 stations to be gated. The big jump is because most of the trips from those next stations are already to stations that have already been gated.
One of the interesting thing to note is that some of the busiest stations around Auckland, namely Panmure (currently 4th busiest), Sylvia Park (6th) and Ellerslie (8th) are not on the list. That’s because while they provide lot of trips, most of those trips are already going to a gated station such as Britomart or Newmarket
