HS2 Interchange in Chilterns area ?

Thanks for the replies, I found it very interesting in how just the presence of a station might affect capacity.

My drivers for this would be;

a) political, neutralising opposition by offering the local region something of benefit. It doesn’t cost enough for that to be an issue, but politically may be vital – this area could be critical to the Tories hopes of a majority in 2015 and rightly or wrongly it may be a mistake to ride roughshod over the locals, because I am ever more surprised at the level and spread of hostility.

b) offer a connection to HS2 services heading north of Birmingham, drawing on passengers from across the region (i.e all along the Aylesbury to London line, Chiltern Mainline and the E-W Oxford-MK lines) – because as it stands, timings and routes for that are and will be rubbish. Potentially even offering better services to the South (of Oxford) and East (of MK) to long distance passengers (again, from north of Birmingham) without the cost, time and clutter of going via London, which as someone who has to use that as a hub frequently, is a miserable experience where you have to change 15,000 times just to end up a sensible car journey from where you started.

I can’t see an interchange station offering any benefit for London/Birmingham destinations as these are already well served for the region, and indeed, the area could expect more semi fasts offering better internal regional connectivity as there will be no end to end expresses, since I assume these will be unable to compete with HS2 at all (in that Chiltern “Mainline” can compete with the WCML).

With “stopping” services on HS1 coexisting adequately, then how would that be impossible for HS2 ? Indeed, the Eurostar from Gar Du Nord ahead of mine today stopped at Ebbsfleet, and that is a long range, international service with a stop, not even mentioning the "stopping at every hamlet" Javelin services.

Personally, I’d build a station and as suggested by someone, not stop much there, but that can come later. Although I agree, road provision to the area isn’t great (yet good enough to support a TMD with no doubt a not insignificant demand for road access ?)


I’m not sure where the last posters rather high handed “stopping at every village” comes from, I can’t see that anywhere in this thread. If there is a reason not to do something, state it, don’t try and conflate the issue to then attack it perhaps ? Equally, given the history of this country, the fact that something is, or isn’t happening already bears absolutely no relevance to whether it is, or isn’t, a good idea, and is simply an outcome of a very chaotic mixing bowl of 1000s of people’s ideas, interests, constraints, prejudices and compromises. I find it hard to think of any Government activity that in the 21st century you would still find someone prepared to just sit back and trust what they say – let alone in the field of railways !

cheers anyway, I'm still minded to think this is a good idea, but not at the cost of reducing overall capacity - I assumed it could be done almost as a "freebie" :D

The "all villages" Up North is a case study where you get Warrington, Wigan, Oxenholme etc.. on what is an express service. It's designed to show what extra stops on HS2 could do.

Comparing to HS1 stoppers then what are you comparing to, the existing SouthEastern services which are basically local to semi fast. HS2 comparison is to WCML where you stop 2 in the Midlands then 1 in the middle. Adding stops to HS1 will bring you back to where we started albeit a little bit faster in between.

Yes connections to The North are good but what towns/villages are on the line that would provide a decent return on? XC stop at Oxford, Banbury and Leamington; VT at Rugby and Milton Keynes; then for the few along the Chilterns can change to XC quite easily like before.

I think major settlements only is fine, however an OOC-Watford Junction-Milton Keynes Central where it would split for Banbury-Kidderminster or Rugby-Lichfield TV-Tamworth-Stafford-Crewe-Hartford-Chester?
Edit: Someone refine it.

HSTed - I'm not entirely sure I'm following your post
Which is why we are now hearing reports of 250m long single deck trainsets that make double sets an impossibility.
My understanding is that the 260m sets will only be used for the Newcastle services.
The government wants the route to be as full as possible as fast as possible after opening, they have no incentive to increase the capacity of the line with 400m long trainsets or double decker trains, or by using dynamic block signalling.
As you keep pointing out in other threads the capacity for a 3tph 400m double deck train service specification will be far in excess of what is offered today. They may not offer 400m double deck services to start with, but I'd rather they built a line that would be able to cope with growth in demand in the future - by coupling sets together, or introducing double deck sets - otherwise where just back to where we are today.

Additionally they must think of the subsidy that will be neccesary to support the WCML services to these cities which are politically neccesary to avoid accusations of "forcing" people to use High Speed trains, this means they do not want to connect towns like Rugby, Milton Keynes or the like to the captive network and remove the only significant source of high cost end to end passengers from these routes.
I'm not following this paragraph at all. If DfT stick to the plan that there will be no premium for travelling on HS2 services they'll be very few passengers that choose to use non-HS2 services to travel between the cities on HS2. Personally, if I lived in MK or Rugby I'd be quite happy that I'm getting more faster services calling at my station, and going to a wider choice of destinations.

Sorry, if I've misunderstood what you're saying.

As for stopping "all shacks" north of Grantham on the ECML...... there arent that many shacks to stop at anyway so there is no significant local "slow traffic". THe station spacings for East Coast services averaged for London-Edinburgh are comparable to those on the Tokaido shinkansen.

Hmm, while there may be similar stop spacing most of those cities on Tokaido line are, shall we say, significantly larger than those on the East Coast. They don't deserve the same level of service.

HSTed - I'm not entirely sure I'm following your postMy understanding is that the 260m sets will only be used for the Newcastle services.
Which means that Newcastle services will waste 140m of train length on the HS2 section of the trip whereas they could run a 2 x 200m formation and have it split at Leeds to run the second half to someplace else, perhaps Hull or to Edinburgh by a different stopping pattern.

As you keep pointing out in other threads the capacity for a 3tph 400m double deck train service specification will be far in excess of what is offered today. They may not offer 400m double deck services to start with, but I'd rather they built a line that would be able to cope with growth in demand in the future - by coupling sets together, or introducing double deck sets - otherwise where just back to where we are today.
The problem with not building the trainsets for high capacity operations (ie double decker from the start, which apparently the DfT do not want) means taht we will be left with a bunch of near useless single deck trainsets that will be of no use anywhere else and have to be taken out of service early so they can be replaced with double decker trains.

Additionally relying on two coupled, non corrdior trainsets as standard causes all sorts of operational difficulties for the simple shuttle proposed, unless they remain together at all times, at which point it is far better to have a long double decker fixed formation trainset. (Using up paths for ECS moves at the start and end of the peaks and stabling all these sets close to the terminii).

I'm not following this paragraph at all. If DfT stick to the plan that there will be no premium for travelling on HS2 services they'll be very few passengers that choose to use non-HS2 services to travel between the cities on HS2.

If the DfT does stick to that rather hilariously impossible plan and also commits to retain a large number of intercity services on the WCML they will have to pay some enormously increased subsidy as the end-to-end loads that currently support the trains calling at MKC, Rugby, Coventry and the rest will be removed.
This however is far better for the DfT than building a Shinkansen style high speed route that would take away the loads at MKC, Rugby, Coventry and Northampton and thus force ICWC to either cease all southern WCML trains which would be seen as a major reversal of the DfTs stated plans to use HS2 as a supplement and not a replacement or be forced to keep them running to destinations that would in no other circumstances support an IC service and pay an even larger subsidy.

Building a line that serves only the InterCity market and is less than half empty is the DfT preferred option because it does not want the political pandoras box that comes with building the route to do the most good for the least amount of money.

They choose to conceal this fact by deciding on running unneccesarily short trains and trains that are just slightly too long to permit doubling up on significant numbers of services, just so they can claim they are routing 14tph from day one when in reality that many passengers would fit in 7-8 or even less.

I'm sure there'll still be loads of end-to-end passengers using WCML and Chiltern services. HS2 is almost certainly going to cost more than traditional services if HS1 is anything to go by. Many, many people will accept longer journey times to pay less. Just look at people using LM for London-MK/Rugby/Stafford/Stoke/Crewe/Liverpool journeys right now.
