It really saddens to see basic proportions and scale, such as Manchester being pictured much closer to Liverpool when it is actually (almost) dead center between Liverpool and Leeds. It's as if planners had a bias since the beginning.

Same with the Eastern leg, it appears to head directly North from Birmingham, making it appear a direct route, when in fact it actually heads back on itself, in a North-Eastern direction closer to a "<" shape as it follows the M42/A42 route, making it look a dubious indirect route.

To head directly North, it would need to diverge somewhere around Rugby, similar to the original Midlands line from Leicester to Rugby, or the Great Central line.

It's really mind boggling how bad this sketch was drawn. They say "East Midlands" to be ambiguous, as on that Longitude it could only be referring to Derby instead of Nottingham, being the last much more populated. And Derby is about the same size as Stoke-On-Trent. (Not Drawned on the map). Manchester's conurbation is 3 times bigger then Sheffield, and is also about the same size as Birmingham's (2,6mi). It clearly deserved a direct route after Birmingham with an obvious station in Stoke in Between. That is basic first principles reasoning. Unbelievable.

HS2 as designed was a perfectly fine scheme, not perfect, nothing ever is, but good enough. It was cancelled because the ruling party is in disarray, nothing more, nothing less.

Bang in. This should be a sticky post at the top of every HS2 thread.


At least on the biggest 5 cities (London, Birmingham, Manchester, Leeds and Liverpool) It would make sense IMHO a direct downtown underground station.

But why underground? HS2 trains were expected to serve a downtown, not-underground station at all of these and at much lower cost.

It’s really mind boggling how badly this sentence has been constructed!

In my mind if a high speed rail is proposed, it should be done right. That translates to fewer curves and more direct routes. Dead-end stations are a no go! And face busy stations, with too much traffic and risking a poor reliability is also not desired. Furthermore, highspeed trains could lose a lot of time Taxiing in and out of city centers. In my view, they require deditated lines and platforms, the whole line must have the ETCS in order to assure ponctuallity and only trains with ETCS enabled should be allowed on that track. I follow at close what they are doing in Stuttgart. The tunnels arriving at the new main station are designed for high speed aproach. If we are already spending billions, let we spend a bit more and do it perfectly. I'm not proposing new stations entirely, I'm proposing 2 platforms underground, sometimes 4 (Birmingham and Manchester, and only if the line diverged to Dublin/Liverpool), just like subwaystations but with larger diameter size for the higher speeds, but nothing too fancy.

HS2 has (and for some cities was ging to have) high speed, direct routes right into city centres (London, Birmignham, Manchester and Leeds). These were all to be ‘above ground (Euston being below ground level, but not tunnelled) Generally speaking the speed limitations were the acceleration of the train once through the point work at the station.

But I don’t understand your preference for underground, other than that is what is done at Stuttgart. Nor do I understand how you propose to put anything more than 10tph each way reliably through any city centre station of 2 platforms with 400m trains configured for long distance travel.

As it stands there will be no released capacity, no reduction of operating costs for legacy services and no income from new services. All that will happen is the legacy classic line services will continue operating whilst haemmorhaging money.
Surely an enormous amount of the released capacity comes from the fact that end-end passengers are no longer taking up room on the trains? What proportion of the passengers on a London-Birmingham train are doing the whole journey? 50%? 75%?

There will be released capacity, and plenty of it, all the way from Birmingham and Lichfield to London.

Each platform can take between 4 and 6 trains per hour. Trains would stop for around 5 minutes, and then go on. I guess on peak hours a frequency of 1 train every 10 minutes. And off Peak hours every 15 minutes. With a main Trunk connecting all those cities, it seems doable. ETCS is a must!

Yes, but the problem is I'm not sure how many of those seats you can sell if you are politically constrained to the current stopping patterns.

I think its far more likely that the trains run shorter or run half empty.

There would not be the same stopping patterns on the legacy network though, so that’s moot.

Overall there is more to gain ecologically from getting High Speed lines built for domestic only transport and rely on the short trip between Euston and StPancras for for those travelling beyond London to Paris and Amsterdam.
Much as I'd love to see through trains to Europe, I agree with this. Birmingham to Scotland is a much bigger market to target than Birmingham to Paris, likewise there are major gains that could be made with London-Scotland, if only the full HS2 network could be built (incidentally why were the Newcastle services proposed to terminate there rather than continue to Edinburgh? Wouldn't London-Edinburgh be faster via Newcastle than via Carlisle?

Would need modification/demolition of the parcels deck
What's up there, out of interest? Presumably no parcels since the opening of PRDC.

True, or a 16 carriage can be sent from Paris to Stratford, divide into two 8 cars, with one going to Birmingham and Crewe, divides into two 4 cars with one going to Glasgow and the other Birmingham, while the other 8 goes to Doncaster, divides into two 4 cars with one going to Leeds and the other to York, Newcastle and Edinburgh
So a total of four multiple units, each with 320kph crumple zones/pointy noses, each with full sets of catering facilities, first class, accessible toilets etc. (let's face it, this is a journey long enough to demand proper catering). Well I suppose that you'll have no need to worry about lack of patronage, you'll have similar issues to class 220s!

And in France the out of town stations are transparently a political sop with, in most cases, negligible actual transport value.
Famously: la gare des betteraves (station in a beetroot field).

Bear in mind that HS2’s Eastern Leg went no further than Leeds, even though services continued to Newcastle.
HS2 post 2b were supposed to manage London-Edinburgh via Carlisle in 3:38.
London-Newcastle was going to be 2:17, current services Newcastle-Edinburgh are around 1:30, so combined you’re not looking faster.
https://assets.publishing.service.gov.uk/media/5a8083d540f0b62302693f4d/NES_Report.pdf is a report into potential post-HS2 upgrades where they concluded the focus should be on the WCML as you can speed up journeys to both Edinburgh and Glasgow.

I thought that it was 3:48 (though I'd have to flick back through Wikipedia's page history to check if this was amended after Golborne was dropped).

Newcastle-Edinburgh are around 1:30
1:24 on Lumo.

Anyway, it's not just journey times, London to Edinburgh has plenty of potential for growth so why not have the extra through services? The existing KGX-NCL-EDB fast service can then serve more stations with HS2 mopping up the through passengers.

Once the full Y-network opens, it will only take around 3 hours 38 minutes to reach London from Glasgow and Edinburgh.

Surely it is the journey time, for the end to end passengers? If it’s faster than the existing ECML route to use HS2 via the WCML, then those are your extra services.

True, unless they're like the Sprinters, but that makes them less aerodynamic.

That states that Edinburgh and Glasgow would both be 3hrs 38 via Carstairs. I'm going to take that with a pinch of salt given that there should be a five minute difference anyway.

Only 2tph with 200m units. Extending the Eastern Leg services allows 4tph to Edinburgh, removing the fast trains from the Southern ECML and freeing up the paths for services calling at more stations. We currently have both slower and faster trains to Edinburgh and even the slower ones are well patronised by end-to-end passengers. 3x200m per hour would just about equal the current London to Edinburgh capacity, so why not go to 4x200m?

You can't be serious. You're joking, right?

Remember that Edinburgh is to the West of Carlisle. Since services to Glasgow would already be going via Carlisle, it makes sense to concentrate investment on that axis.

What investment would be required other than a few extra "classic compatible" sets on the rolling stock order?

To some extent this makes sense, but the problem with that is there is no significant population, other than Carlisle itself, between the Scottish Central Belt and Lancaster!

The railway is through empty terrain where there is noone around to use it.
Going via Newcastle is marginally longer, yes, but the railway infrastructure will be utilised far more efficiently than otherwise.

The East Coast Corridor is the far superior one for investment because there are far more people around to actually use it.

Edinburgh is West of Carlise?
Yes, Edinburgh is also west of Bristol. The railway doesn't run in a straight line however, so you have to go the long way around to get there.

I make the difference between London to Edinburgh via Newcastle vs via Carlisle to be around five minutes (could swing either way depending upon which figures you believe).

The northern ECML needs upgraded power supplies (they're already an issue) but with that done (not to mention the full HS2 Y) I see no reason why we shouldn't make the most use of it by running more trains to EDB.

So was I. Edinburgh's longitude is 3°11'W, Carlisle is 2°56'W, Bristol is 2°35'W. In fact Edinburgh is pretty much due north of Cardiff.

Longitude is pretty irrelevant though when considering the topography, Edinburgh via Carstairs is still a bit of a long way around.

This image from Google Earth with lines of longitude added illustrates it well. Edinburgh is further west than the vast majority of England.

Wow, always thought that Edinburgh was East.

It is if you're in Glasgow.

The westernmost railway station in Great Britain isn't Penzance, either. It's Arisaig in the Scottish Highlands.
Wow, really makes you appreciate that the Earth is a sphere but also how maps often displace things wrong.

Yeah, the Mercator projection makes Russia and Canada look five times as big as they really are. But we digress.

Going back to the original question, I think that the lack of a connection between Curzon Street and Bromsgrove/Banbury was a mistake. There could have been an opportunity to sort out XC properly by integrating the planned Birmingham to Manchester/Leeds/Newcastle/Scotland HS2 services into the rest of the XC network. Birmingham to Newcastle would have been cut by more than an hour had the Eastern Leg been built but passengers from Bristol and Oxford would have needed to use the existing services to New Street and jump on a tram.

Fully agree, one mistake was to make Curzon Street a HS station only, meaning only HSR trains will call there.
