Ce n’est pas un tunnel au milieu de nulle part, c’est un tunnel pour rattacher le centre-ville au réseau ferré existant qui passe majoritairement en périphérie:

In the sense that New Zealand is quite remote for most I’m guessing.

Haaaaaa peut-être bien ^^.
Exactement:
On dirait que tout le monde peut construire pour beaucoup moins cher que nous… Même des néophytes (1er métro) au milieu de nulle part.

A $2.9 billion project to extend Metro-North Railroad service into New York City’s Penn Station has been delayed by about seven months, Metropolitan Transportation Authority officials said Monday.
The hold up is because the MTA relies on the owner of the existing tracks, Amtrak, to allow access to those lines during construction. While the MTA has a deal with Amtrak to open up the tracks and provide staffing, it has yet to fully deliver on that commitment, Jamie Torres-Springer, president of the MTA’s Construction & Development, said Monday during a monthly committee meeting.
“They have been unable to live up to this agreement to date, and we have ensured that they have been on notice of that, Torres-Springer said during the meeting. “The good news is that Amtrak acknowledges these problems and in part, due to that strong agreement that we negotiated with them, they’re working collaboratively with us on a recovery schedule.”
Metro-North operates through Grand Central Terminal on Manhattan’s east side. The Penn Station Access project is now set to finish October 2027 instead of March of that year. It will shorten commute times by about 50 minutes each way and connect the East Bronx, New York City’s northern suburbs and Connecticut to Manhattan’s west side.
The project includes building four new accessible stations in the Bronx and upgrade Amtrak’s Hell Gate line. Amtrak didn’t have an immediate response to the MTA’s comments on the delays.
The MTA, the largest US public transit agency, wants to avoid potential cost overruns. A similar problem with Amtrak resulted in about $1 billion of additional expense to bring Long Island Rail Road service to Grand Central, which began last week, Janno Lieber, the MTA’s chief executive officer, said during the meeting.
That project, called East Side Access, required the MTA to rebuild Harold Interlocking in Queens, the nation’s busiest rail interlocking and part of Amtrak’s Northeast Corridor line.
“We have delay,” Lieber said. “We have a repeat of that Harold Interlocking dynamic, but we have legal rights and none of us wants to exercise them. Amtrak is our partner and in fairness they’ve been trying to improve.”

This video gives a perspective into what we get wrong about HSR and public transit.

We often close roads or create diversions that last for months for various construction work. Here’s how they do it in the UK.

Lol HS2 phase 1 is less than 200 km, and is projected to cost £42 Billion (~CA$68 Billion). Someone needs to explain to me how we’ll get a phase 1 HSR between Montreal and Toronto, 500 km, for $12-18 Billion…

They are tunneling through London again and adding several green tunnels (cut and cover). Of course its going to be expensive. There’s also 10 platforms at Euston, the complete reconstruction of Old Oaks Commons…

I’m assuming that not building brand new tracks underground in the middle of the forest should help and not building stations as massive as London’s terminal station should help.

Here’s another interesting video. I remember a while back we had an argument about central platforms and how they require trains to slow down. In this video at 1:32:20, you can see a train driving at 100km/h right through one of those central platform station. It is actually quite a pretty station, with planters in the middle of the platform. For regional / commuter trains, that’s more than acceptable. There are several other exemples of central platforms in this video.
So you’re saying we should half-ass it again, as usual. Got it.
I mean, is it that or does the UK follow the general trend (most extreme in the anglosphere countries) of massive overbuilding, to the point where budgets become unmanageable?
So you’re saying we won’t do that (for the first time in a century)?
Nono, we are definitely one of the worst offenders lol. I thought you were trying to say that was the non half assed way of doing it
Just wait until we see the massive cavernous mezzanines of the blue line extension. 6 billion will make sense very quickly

Well, if you consider us one of the worse offenders, I would argue that the UK gets a heck of a lot more value for its money than we do. I’ve watched enough documentaries to know just how much of a stickler they can be for tiny details. We accept things that would never pass over there. Even a single panel that it out of alignment is grounds for a rework at the expense of the contractor. We don’t seem to have that kind of culture for public transit.

All of that perfection requires them to spend massively more though. And it’s all at the cost of the project timeline aswell. Crossrail was delayed to all hell just to make sure it was absolutely perfect. I don’t know if this is the right route to go with our transit. I obviously want quality, but things that aren’t built because they’re too expensive or things that are delayed 5 years because of minor issues represent transit that isn’t moving more people
Projects in the US and Australia are also similarly (horrifically) expensive, delayed, and while they are “perfect” when they open, it’s all so painful and dissuades future investment in transit
Wait US transit projects are not perfect when they open lmao, don’t know why I included them in that. The finishings on the Grand Central Madison project were really rushed despite being very delayed and very over budget

The US has been building LRT systems for the last 2 decades, and they are easily some of the worse transit systems on the planet. They have low ridership. They are slow because of just how many interactions there are with street traffic. They have a low frequency because of the fact that they run on streets. Many of them have stations that are located in the middle of highways. Los Angeles is particularly notable for that. Some of them don’t even have pedestrian access and connect only to BRT routes.
The US also has quite a few of those airport PRT systems that take you on a 5 minute ride to the nearest metro station because of the financing rules that they used to have.
To put it that way, US system are way beyond “not perfect”. They are an aberration. We really should not be comparing ourselves with some of the worse exemples of transit on the planet.
I was thinking more New York city 2nd Avenue subway, 7 train extension and east side access United States. And less los Angeles green line. But yea, all your points still stand
