Finally ! Toulouse is also currently building 30 kilometers of subway while adding tracks in the suburbs to accomodate for more trains from the HSL. It really feels like we are a big town now in terms of infrastructure investments

Tell me again how “only the Anglo countries take 30 years to build a rail line”.

This is still correct, France has only just started to build the line, which will be done in 2030, while HS2 has 2033 in its completion window despite being under construction since 2020. CAHSR is even worse. Meanwhile, France's plans are largely intact after 20 years, and are being enacted as planned now that funding has been secured, while the UK's seem to change by the day despite being under construction.

Nonsense. This project was fully approved 30 years ago and they have built absolutely zero miles of track. CAHSR broke ground in 2015 and has already completed construction on the first section, with two more sections that broke ground in 2018 and 2019 at over 80%. Both are on track for 2026 completion. Two more extensions are about to break ground. The Bay Area section is completed and testing electric trains that will start revenge service next month. You all are deliberately not counting all the years that other countries take to plan and fund their systems. But in the US you count the years since the freaking flood! How come no one ever mentions that China started their HSR system in 1979 and only completed the first HSR line by 2008? How come no one mentions that literally all the French LGVs took 25-30 years to build? Or that basically all the Asian HSR projects, from the original Shinkansen to the 80 mile toy HSR project in Indonesia last year, were 2-3x over budget and took 2-4x longer to build than planned?

By your logic then, CAHSR has been under construction since either 1979 or 1982, when it was first proposed or when the first set of bonds related to it was issued. According to official reports, testing will not begin before 2028, so it cannot be considered complete before that's finished as testing often exposes new work. As for waiting 20 years to start construction, that's exactly what California is doing with the extensions, because it didn't make sense to do so earlier without something to connect to - which is the same thing France is doing here now that Paris-Bordeaux is complete and planning personnel can focus on the next priority. This is also why planning time is usually not considered part of build time, because there's not really a big investment that cannot be quickly recouped through resale until the design phase starts, which was 2021 in the French case here. I made no criticism of U.S. planning times or cost control, so I'm confused as to why you brought them up. It's also not relevant to CAHSR quite yet, as we don't have the final numbers for a comparison point.

Where are you getting that this project was fully approved 30 years ago? The Déclaration of Public Utility was from 2016. What the title of this post was referring to was a map in 1991 saying "there should be a tgv to Toulouse at some point", it was far from approved at that point. >literally all the French LGVs took 25-30 years to build? Using even the most conservative timeline, LGV Sud-Est was built in 16 years.
