And even if you generate it from fossil fuels, it's still more efficient to generate at a centralised power station with careful emissions control and designed for a lot more efficiency. With good infrastructure the transmission losses are minimised so the total fuel to movement efficiency ends up favorable. Then, when you come up with some other form of generation (I was reading earlier that energy costs in some parts are at fuck all at the moment due to overflowing hydro dams, or maybe we'll finally figure out fusion) you simply supply that onto the grid, never mind converting all the engines to some other form of fuel/engine.
The other advantage is that it makes it a lot easier to do other things (less important for trains admittedly) like having brakes that recharge a capacitor bank rather than dump the energy as heat, which is where more than half the energy used by a car driving around town goes...
you guys invented two strokes, theres simply no way us yunguns can compete with that, i think may of us are disheartened and perhaps even afraid to try, but fear not ye olde citizens, im currently working on artificial intelligence at massey university, we have a great team there and should crack it any day now.

That's one in the world without support, subsidies or protection. There are thousands more. Most rail companies throughout the world make annual operating profits in the billions.
In the mid 90's when Ed Burkhardt (from the Wisconsin Central, a massive American company) got involved and bought NZR and renamed it Tranzrail, they made profit. Quite alot actually. If you want to know what an efficient and profitable rail operation in a mountainous island with a small population looks like, google Tranzrail.

We don't have a good electricity supply infrastructure (losses at 40% and up) and no political will to do anything about it. Trucks are key to our economy. Start using the trains for everything and watch supermarkets empty in a matter of days.
What about roading hubs constructed around railheads? Not there at present, so expect worse congestion if heavy vehicles are confined to a radius around current distribution infrastructure.
If a man is alone in the woods and there isn't a woke Hollywood around to call him racist, is he still white?
To those that are all nostalgic and yearn for the days of old - and those who have trouble working out which is the red and which is the green bling button.
Those who fail to learn the lessons of history are doomed to repeat it. We had rail - it was protected (of necessity) it didn't work. That's life, get over it, move on, because rail hasn't.
Still going back and trying failed paradigms again and again seems to be a big part of life in NZ of late.
You're suggesting we encourage NEW paradigms to fail?. People who support trucks don't do so with any indepth logic behind thier arguement, they just argue for trucks because they're passionate about them. It's always the same old fall-backs "NZR failed, how would we get goods from railheads onto shelves, blah, blah, blah...". Never with any scope on WHY they failed, or how road and rail actually inegrate etc... Stop worrying truck-heads... there will still be trucks for you to put posters of on your walls and draw pictures of and make models of and generally idolise. There just wont be so many of them ruling the roads whilst chewing them up, and because there's less of them, each of your beloved boner-inducing rigs will be even more special![]()

NZR didn't fail. It actually succeeded very well. Thing is, the measurements of succeed and fail changed. NZR was set up to maximise the public good. It succeeded by that measure. But Rogernomics demanded that everything be measured by private profit. At which NZR (naturally) failed. Public good and private profit are almost always incompatible. Then of course Tranzrail failed the private profit test as well. Also not surprising. Rail systems are capable of generating large social dividends. They're not good at generating corporate dividends if they are competing with trucks and such like. Not because trucks are "better" than rail, but because everything about trucking exists to maximise corporate profit. Which is very seldom the case with rail. To assess whether Kiwirail succeeds or not, it is first necessary to decide whether it should be run to maximise private profit; or to maximise public good. I prefer the latter.

If you're going north from Mangere Bridge and take the Neilson St exit, it curves around and goes back under the motorway, but not before going past little old Onehunga Port. There's trucks going in and out of there all day, to load the ships up and take cargo away.
There's a little section of road, about 200m long, which comes from the motorway and goes as far as where one must turn off the road and into the port. This strip of road -- and only this strip of road -- is the roughest, most horrible, rutted (?!), bumpy piece of crap ever. You can see the deep furrows in the road where the trucks hit the brakes before making a right-hand turn across the road.
Past the port, the road becomes a perfectly-sealed ordinary NZ road once more, free of surface imperfections.
That small section of road has been resurfaced twice in the last 18 months. Each time it takes roughly 3-4 months before it turns back into shit.
Ixion makes a good point. Public good vs. private profit... you don't charge money for hospitals. Treat rail as a public service, if you can't make it profitible. Lots of modern tech these days to reduce operating costs.
