The problem isn’t how they’re constructed, it’s how they’re run, and this article is basically just complaining about SNCF without realising it. They run bad timetables and aim for high occupancy rather than transporting more people. Jon Worth has better writing on the topic IMO.
That’s really a great article, thanks for the link!
Still, there’s plenty of criticism in the article I linked that is not touched on, I hardly think it becomes irrelevant by reading Jon Worth’s writing! Even with his proposals I’m really not sure if we would get back the cheap and still relatively fast connections that have been removed. To me there’s not a clear benefit to getting rid of the old “low-speed” rail even if we fix SNCF.
It’s cheaper to run a high speed service than a low speed one. You can transport more people with the same number of staff and trains because it runs faster. The solution isn’t to run an artificially cheaper low speed service along side, it’s to run the high speed service in a sane way.
Is it really? Because that claim goes against my intuition so if it’s true I would be happy to get more details! But what you say doesn’t quite make sense to me, sorry if I seem pedantic: transporting people faster is not the same as transporting more people. You transport more people per unit time, but not necessarily in total. I also don’t see how faster trains need less staff. When you say it’s cheaper, do you also take into account investment cost, or do you neglect those and just mean operating costs?
