An Auckland train ride

I took a train ride for the first time in Auckland for many years, from the shiny Britomart Station (pictured left) all the way south to Middlemore Hospital. It was just after rush hour (18:26), and the train was surprisingly rather empty, perhaps 20 people in our carriage, which could easily hold 200.
The system (map) has been ramshackle from its origins and for many decades neglected in favour of road building. Lately they are upgrading the network, but it's still diesel locos and narrow in and out to Britomart, which is a major bottleneck preventing an expansion of the number of services into this station. Why do engineers only build for the present and never for the future?
Anyway, a longish tunnel out and then a swing into Parnell up to Newmarket. Quite a long distance, there really should be a Parnell Station for the suburb and a bridge to the university if they ever want to up ridership. The train goes remarkably slow - slower than the London Underground, I reckon. And there is a train conductor too, who collects fares and decides when doors open and close and when the train starts rolling again. Of course, this being un-integrated Auckland, my Fullers monthly pass for ferry and some bus services is certainly not valid on the train. It'll be a good time before we get anything like an Octopus or Oyster card (our version is going to be called "Hop Card" - but don't hold your breath that it will include Waiheke). The fare was $4.10 for about 30-minute ride over 16km. Not a bad fare considering we pay $17.50 for a 40-minute ride over 22km on the ferry - especially since train infrastructure of rails, stations, land, electrification, rolling stock sounds to me more expensive to set up and run than a ferry terminal and a couple of ramshackle boats.

Middlemore Station is very conveniently located when you want to visit the hospital or attend the local schools (we were invited to a Xmas function at King's College). But the other stations like Remuera, Penrose, Westfield or Otahuhu are really in the middle of nowhere, or rather in an industrial wasteland - pointing to the original purpose of the Auckland rail network: goods transport to and from the industrial zones to the port and the hinterland. It was never conceived or designed as a passenger network, and I can't really see how they are going to get the stations closer to homes and businesses where people actually want to travel.
