What is the overall impact on end to end Norwich - Cambridge journey times as a result of the extra stop? And will all CBG-NRW trains stop?
Thanks!
All stopping, hence my earlier coffee comment![]()

You'll need to set up a repeat Deliveroo order![]()
because the current Kings Cross-Cambridge only fast (and return) service that's being extended to Ely Monday-Saturday doesn't exist on Sundays- only 3tph GN CBG-KGX(!). Of course, I'd have thought that Sunday passenger loadings would be able to cope with the KLN-KGX putting in a stop at Cambridge North.
Testing of passenger trains has begun at Cambridge's newest station ahead of its opening at the end of May.
An eight car class 317 train was the first to stop as planned at platform 3.
Trains will now be calling four to six times daily as train operator Greater Anglia puts the station's tracks through its paces.
A formal handover of the three platforms and rail systems to the operator will be made on April 21.
I'm assuming that the trains calling "four to six times daily" are ECS services.
May 21st is what they've been very publicly saying- 1st day of new timetable. Current 1st train is the 0850 from Cambridge to Norwich, arriving CMB 0854.
After that there's the 0925 CBG - CMB (arrives 0930)- this will form the 0944 to Liverpool Street.
First GN train is the next day, the 0540 to KGX (the 0454 departure from KLN)
Does anyone know if Cambridge North will have a ticket office, or will it just have TVMs?
I emailed Greater Anglia, they confirmed that Cambridge North will not have a ticket office but will have a number of ticket machines and platform hosts there to assist customers.
A spokeswoman for [Great Northern] explained that services stopping at both Cambridge North and Waterbeach were restricted by overcrowding and infrastructure pressures.
She said: "There will be a few trains calling at both Waterbeach and Cambridge North, however this is due to King’s Lynn to Cambridge services calling at all stations including Waterbeach already being very busy.
"We are acutely aware of the high demand of the current services and have added in additional Ely services calling at Cambridge North or starting at the station to manage this demand and take the pressure off the King’s Lynn to Cambridge services.
"From December 2018, we will be able to offer more direct services between Waterbeach and Cambridge North, once Network Rail have carried out the platform extension upgrades between King’s Lynn and Cambridge, allowing eight-car trains to call at Waterbeach station."
A Network Rail spokesperson said: "We know that overcrowding on the King's Lynn services, particularly in the peak is an issue. That's why we're currently developing a scheme, in close collaboration with the operator, to lengthen the platforms to allow eight car trains to run.
"We have no confirmed timescales for delivery of that project as yet, but we'd hope to do it by the end of 2019."
The Waterbeach Barracks development proposes both lengthening the existing platforms as a short term measure and relocating the station (closer to the development, which will have 6-10x the population of the current village) in the long term (presumably as something a little grander than two basic platforms, a couple of ticket machines and a couple of bus shelters staggered across an automatic half barrier crossing)
For most of the day, NRE offers a double-back via Ely as the only way to do Waterbeach to Cambridge North, requiring two tickets, costing a total of £8.80 for a single.

National Rail Enquiries now offers Waterbeach to Cambridge North via Cambridge, as well as via Ely, but says that via Cambridge also needs two tickets - one anytime single (£2.50) and one off-peak single (£2.30), coming to £4.80 total.
I do wonder if there will be political pressure on the metro mayor to get the Waterbeach platforms (temporary 8 car version) issue sorted so the Ely terminators can stop there? Could be a quick win.
As these presumably will be using 387s shortly which have SDO, couldn't 2x387 call at waterbeach using SDO ?
It really is rather frustrating that no-one seems to have seen this situation coming and done something about it ahead of time.
There's also the element of not bothering to do anything drastic until the Thameslink timetable recast comes in. I don't think there's anything infrastructure-wise that will cause problems with both Cambridge fasts (extended to Ely) stopping at Cambridge North? I imagine it isn't included initially just because it doesn't quite work as is, and there's no major point getting it to work for a year or a year and a half.
This does result in an alarming number of trains skipping Cambridge North, however, as a glance at the GN timetable shows. The complete avoidance of the station on Sundays, for example. They do seem to be treating it as an operational inconvenience, rather than a boon for transport in the Cambridge area.
