GTR have posted a consultation for their proposed Great Northern May 2022 timetable.
Link is as follows

From what I can see, the obvious changes are as follows:
* Cambridge to Brighton services all call at Ashwell & Morden. The Cambridge to King's Cross services generally lose their Ashwell & Morden call.
* Welwyn to Sevenoaks happens
* The KX to Baldock peak services are abolished, instead the Cambridge to KX stopping service is amended to run fast south of Hitchin but calls at Welwyn North in the up direction, and Knebworth and Welwyn North in the down direction.
* The two late evening Baldock services are replaced by two Cambridge services, which call at Finsbury Park, Welwyn North, Knebworth, Stevenage, Hitchin, Letchworth, Baldock, Ashwell & Morden, Royston and Cambridge.
* In the peaks there is a Letchworth to King's Cross stopping service which picks up the calls south of Stevenage, and calls additionally at Alexandra Palace.
* All the King's Cross to Cambridge stopping services now call at Alexandra Palace. The up service is roughly as per today, the down service is completely retimed.
* Peterborough to Horsham services call additionally at Knebworth during the morning peak, in the up direction only (replacing the former Baldock services).
* Inners largely stay the same, however Brookmans Park and Welham Green get 4tph, which includes some calls from Sevenoaks services where needed to make up the numbers.
In my view it's a bit of a mess. Some through journeys are being lost, and it seems to benefit some less-used stations like Foxton, Shepreth, Meldreth and Baldock with London journeys, whilst disadvantaging rather busier stations in particular Hitchin. If usage returns to anything near what it was, the 8-car services on the Cambridge to KX route will fill up quite early, whereas today they start at Balcock and hoover up a lot of passengers at Baldock, Letchworth and Hitchin, all of which are very busy. I suspect this will push passengers onto the new Letchworth starters, leaving less room for people at places like Welwyn and Hatfield. Essentially it's undoing one of the positive features of May 2018 which does at least spread capacity across the whole route. I also don't really see the value in the Alexandra Palace call in the stopping service, it already has an excellent London service both peak and off-peak, this seems to be more for operational benefits than passenger value (I suspect it's a case that it would otherwise have been pathing time). Personally I think May 18 offered a better range of services. It looks like Cambridge to Maidstone is as far away as ever.
