SN, GN and TL are in, no major changes to the Thameslink timetable except Brighton-Cambridge goes to 2tph. Maidstone-Welwyn doesn't start and Beckenham is still SE.
Interesting to see the second Cambridge/Brighton seems to wither away in the evening, unless there’s more to be uploaded (which given that the incoming paths at Cambridge have subsequent paths taking the stock to the sidings would seem to be unlikely). Strangely there's now a Brighton-Royston and return Royston-Brighton service in the morning (perhaps an outcome of limited stabling accommodation in Cambridge?), watch out for that one being turned at Letchworth in the slightest event of problems! There's also a new 06:03 King's Cross-Cambridge service which is part of the second Cambridge/Brighton sequence.
Another small change is some but not all Cambridge/Brighton services now call at Ashwell & Morden - currently only one morning service does. I'm not sure if this was always planned, or has been in response to user demand (the problem with Ashwell being served by the 387 services is that they will always find themselves on a busy train, and in the up direction likely finding all seats taken on many services - and at off-peak times always being confined to the slow services which especially in the down direction take a very long time).
The consequential changes appear to be largely as predicted - virtually all the Royston 365 services revert to Baldock with just one early service from Royston remaining (perhaps those who don’t like ironing boards will make a bee-line for this?!). The lunchtime Letchworth reverser remains - I’m not sure when the Barrington freight flow ends and if that will have an impact in the future? The hourly Stevenage-Moorgate 313 service is now cut back to Watton-at-Stone with a bus to Stevenage, although the few early morning / late evening services which run to Stevenage for access from/to Letchworth sidings continue to run in service.
A few minor changes to reporting numbers, mainly tidying up things which probably shouldn't have arisen in the first place (for example the lunchtime Letchworth reverser now correctly has a 2R** reporting number, and various empties out of King's Cross to Hornsey now correctly have 5E** reporting numbers) and a very minor swap round of the 365 diagrams in the evening (but nothing of consequence). A very few minor changes to platforms at King's Cross as well. Also one of the morning Peterborough core services now originates from Horsham instead of Gatwick Airport.
Will have a look at the inners when I get time!
