Sutherland was clearly on about improving the experience on trains. Not about making it better only for 1st class
Where he does have a point is that rail travel does not do much to make itself attractive and everybody has their own personal horror stories, and there are hundreds of threads: Overcrowding, delay, comfort, connections, accessibility, cost and the risk that honest mistakes with tickets leads to somebody with a name badge ripping up your ticket and treating you like a criminal.
Yes. Because building 320km/h high speed lines is standard whereas 360km/h or 400km/h is bespoke.
Going from 200km/h to what has been designed was apparently 9% saving in the design phase. We are saving 2-3% by descoping the train speeds. Collectively this is about £11Bn at current forecast. This is clearly not the major factor in the cost going from £35Bn to £100Bn.
I haven't justified the cost of HS2. It has been inflated by political meddling, poorly written contracts, a planning system not fit for national infrastructure projects, and external factors beyond the control of the DfT (materials inflation caused by covid and the Russian invasion of Ukraine).
That doesn't mean that the basic premise behind the project - that the WCML is full (something you deny in spite of all of the evidence produced by the experts) and that the best way to solve this collar on our economic growth is to build a new line - was wrong.
Absolutely. One mistake this forum (and many others) keep making is comparing Actual HS2 to an imagined alternative scheme that was better. That is frankly magical thinking, because the issues with HS2 do not really relate to its design speed, or the route it has taken.
At the time people were learning from the French that it'd be good to future-proof higher speeds, Government was also failing to learn from the French about what an effective delivery approach to high speed rail looks like. Whilst HS2 Ltd was being stood up and thinking about design, the French were cracking on with LGV Tours-Bordeaux, delivering 300 km for €8Bn.
As
@Krokodil says, the political meddling (desire for immediate tangible progress vs risk of summary cancellation), planning system and also government/supply chain inexperience of delivering projects like this led to a push to award main contracts when the designs and consenting were too immature. This led to badly written contracts, re-work, scope creep, delay, waste and cost.
Can the existing WCML really be improved to the point that 186mph would be possible? I would be interested to know how that could be done!
It would be quite easy to go through Berkhamsted this speed. You'd only do it once, mind and you'd literally be
going through Berkhamsted, but hey the castle was already ruined, you just finished the job. Serious point is that getting much more speed out of the WCRM meant segregation (4/6-tracking) and getting rid of wiggly bits with bypasses as part of a structured, long-term programme. However, this still blends lots of online upgrades (see WCRM) and new-build (HS2). I do not understand why people just assert it'd have been delivered so much better than HS2.
Plus, said programme is much easier to cancel when it's half-baked, as MMLE was for the umpteenth time last year.
