Fascinating - I'm really surprised by this; many thanks!And it doesn’t really drive any material incremental benefit.
(Out of interest if the 12 stops is 90-95 mins end-to-end, does this mean that an express service would be 70ish?)

At a very early phase of design by Network Rail then sub-60 minutes was on the table, but that was ‘blue sky’ 125mph straight as an arrow alignment thinking.Fascinating - I'm really surprised by this; many thanks!

I suspected that was the case. Going full circle though, surely any through service at Cambridge be it from the south or from the north requires the same interventions on the opposite side unless it is only a partial through service. Sending everything from the south to Ely/Ipswich/etc is going to need the same platforms and presumably the same four tracks north to Coldham's Lane. If anything, if everything at Cambridge was a through service it would reduce any new platform requirements?This excludes any costs associated with upgrades south of Cambridge station to enable EWR services to run-through to Cambridge South.
You also have to do more work in Cambridge station itself because the platform plan only works if EWR northern approach terminates at Cambridge.
These extras make northern approach more expensive if you want through EWR services to Cambridge South.
EDIT: i.e. defeating the point of selecting a northern approach to save money.
As a comparison, Google reckons the fastest you could drive Oxford to Cambridge is 110 minutes, but gives a wide range up to 3.5 hours.End to end with 12 intermediate stops would be roughly 95 minutes.
With ideal pathing it could be done sub-90 minutes, but that’s not likely to materialise in practice.
And it doesn’t really drive any material incremental benefit.
Driving will be quicker than today (and more reliable) when the Caxton Gibbet - Black Cat dualling and Black Cat interchange work is done, presumably ahead of the EWR opening. Moreover, the competitiveness will depend on your starting point and destination in Oxford and Cambridge are, given how poorly sited the main stations are (thank you, colleges). A 75 min journey would be much more likely to maximise modal change from road to rail, I'd argue.As a comparison, Google reckons the fastest you could drive Oxford to Cambridge is 110 minutes, but gives a wide range up to 3.5 hours.
Going via London by rail (once Nuneham Viaduct is fixed again) is around 2 hours 40.
So a 95 minute stopper is still going to be extremely competitive.
No, this is not actually the case.surely any through service at Cambridge be it from the south or from the north requires the same interventions on the opposite side unless it is only a partial through service
No, not from a southern approach. Pretty much the only thing you would need is to convert the bay at Cambridge North into another through platform, but that’s about it.Sending everything from the south to Ely/Ipswich/etc is going to need the same platforms and presumably the same four tracks north to Coldham's Lane
It would reduce bay platform requirements, but this then presents a problem for the northern approach proposals which rely on (in effect) terminating EWR services in the western bays (5 and 6) and terminating Norwich/Ipswich on the eastern side. Obviously, you can’t do that if you are running EWR services through.If anything, if everything at Cambridge was a through service it would reduce any new platform requirements?
The Cambridge stations (3 of them by the time EWR arrives) may be poorly sited for the old City Centre, but they are well sited for where the employment is. That particularly applies to the Biomedical Campus and Cambridge South, but the area around the old station has been transformed in the last 10 years and is now a major employment hub in its own right.Driving will be shorter and more reliable when the Caxton Gibbet - Black Cat and Black Cat interchange work is done, presumably ahead of the EWR opening. Moreover, the competitiveness will depend on your starting point and destination in Oxford and Cambridge are, given how poorly sited the main stations are (thank you, colleges). A 75 min journey would be much more likely to maximise modal change from road to rail, I'd argue.
Coming in from the south offers many possible places to extend services to beyond Cambridge if desired on a range of lines, while all easily serving Cambridge South if desired and some also being able to call at North (which has potential for expansion). Most are a logical continuation in the same general direction so are more likely to generate cross-Cambridge journeys too. From the north, there's only really Stansted as a logical terminus which couldn't cope unless EWR trains replaced another existing service from that direction through the single track north chord and tunnel under the runway. The Royston line would be a possible destination from the north too but I can't see anywhere to go along that line that would be useful for journeys from the west beyond Cambridge South, so trains might be running empty to any notional turnback location, and its a capacity constrained line too with mixed stopping patterns. The southern approach, 'automatically' serving Cambridge South station, is far more sensible in my opinion.It’s not that simple because you would have to expand capacity between Cambridge and Cambridge South to run anything more than a token service each hour. That increases the costs significantly, but is already being done on the selected southern approach.

We very much appreciate the work that goes into getting these things over the line, whether we're familiar with the problems or not! Thank you, once again.You won’t believe the difficulties I have had in trying to ram home this message, not that the NIMBYs actually care about the realities of such things.
I'm very curious about this! Could you please elaborate why this is the case? I just can't see how the exact same number of services wouldn't require the exact same infrastructure. If you have 4 trains extra an hour from the south heading north it's no different to 4 extra trains from the north heading south. They have to come back the way they came if nothing else!No, this is not actually the case.
It’s a combination of the absolute capacity of the line, pathing and platforming.I'm very curious about this! Could you please elaborate why this is the case?

My thoughts entirely. I realise the argument for (at least) getting the line built, but there must be a dividend - especially on new alignment - of doing it when the line is built, rather than doing it later.This is such a depressing line to read. That the industry has been taken in by the promises of batteries and bionic duckweed as an alternative to OLE for a line like EWR is terrible.
EWR - possible eastern extensions from cambridge to norwich and ipswick by Mwmbwls, on Flickr
Onward EWR connection to Norwich and Ipswich was an option suggestion with each destination having an hourly service.IIRC this was suggested by the local councils. Norwich may have taken its EMR link to Liverpool as a precedent.
If Stansted were expanded to two tunnels, would it make a better destination than Cambridge North?And we have a winner!

On a new line, the argument for not electrifying is so much weaker than it was on the Oxford-MK section. At least the argument about not having to rebuild existing bridges was present there.My thoughts entirely.

To one destination and with less scope to deliver wider EWR connectivity to Norfolk and Suffolk in the future.If Stansted were expanded to two tunnels, would it make a better destination than Cambridge North?
It's quite a long way, through not very much. Is there very much demand - how busy is the XC service to Stansted?If Stansted were expanded to two tunnels, would it make a better destination than Cambridge North?
The tunnel under the runway is just one of three capacity constraints at Stansted Airport. The north curve is also single track. The station only has three platforms, one of which (platform 2) is short, only taking 4 car trains. When Stansted Express is running at 15 minute intervals then the short platform 2 is the only platform available for all other trains.If Stansted were expanded to two tunnels, would it make a better destination than Cambridge North?
That's fair enough - and living in Ipswich I'm obviously biased in the other direction!To one destination and with less scope to deliver wider EWR connectivity to Norfolk and Suffolk in the future.
The previous plans had 4tph between Bletchley and Cambridge, but the 2tph starting at Bletchley have now been shortened to only run from Bedford.That seems to be what EWR is proposing. This is the "proposed train service pattern":
Was the 4tph between Bedford and Cambridge always in the plans?
Not to mention the potential for freight – approaching Cambridge from the south means that trains could continue straight through and on to Felixstowe, whereas coming in from the north wouldn't allow that without a reversal, which is not what you want to do mid-route with a freight train if you can avoid it! (Whereas for a passenger train to reverse at Cambridge, where it will be stopping anyway, doesn't actually make a huge amount of difference)Coming in from the south offers many possible places to extend services to beyond Cambridge if desired on a range of lines, while all easily serving Cambridge South if desired and some also being able to call at North (which has potential for expansion).

Certainly not any existing deep-sea intermodal I agree. Maybe other future flows of unspecified nature, and not envisaged yet. Then in the longer term plausibly, new north-facing connections might be added as well! We probably shouldn't be mentioning the freight subject here again before the line's safely finished though.

That’s what I thought. The poster was suggesting it was another consultation, I was thinking don’t we have enough already?
Hmm. The Stansted branch is long overdue a capacity upgrade
If Stansted were expanded to two tunnels, would it make a better destination than Cambridge North?
No, physical infrastructure costs only.Do the costings for the Northern route into Cambridge include the cost of delays on the A14 whilst building a crossing for the railway?
That was largely because of deliberate scare-mongering by the two main NIMBY groups, both of which knew that what they were putting out was untrue.We probably shouldn't be mentioning the freight subject here again before the line's safely finished though. I recall it being quite a controversial subject among the locals en route!
