Trying to answer all points here:
- The 2022 Timetable will see the Maidstone East service (Southeastern replacement for Thameslink) still run even on Sundays; but on Sunday it runs via the Chislehurst loops and Grove Park to London Bridge and then Cannon Street or Charing Cross at bidder discretion. This is every 30 minutes.
- During the Monday to Saturday period, however, it will operate via Catford (which therefore only has to accommodate a fast path every 30 minutes during off-peak, which is perfectly adequate) to Blackfriars.
- The Victoria to Ashford stays at 30-minutely via Herne Hill; albeit fast from Victoria to Bromley South.
- Once Thameslink have sorted themselves out and got the Welwyn to Sevenoaks running, that means Southeastern effectively have free use of the two bay platforms. A half-hourly Maidstone, half-hourly Beckenham additional Metro service and I strongly suspect a half-hourly Blackfriars to Medway are likely. I don’t see the peak Medway extras being from Victoria but I would like to be surprised.
- Victoria to Lewisham will be half-hourly from May 2022, all day. Half-hourly to Hayes and at least Crayford via Sidcup each. So Victoria to Denmark Hill will be very reasonably satisfied. So will Denmark Hill and Peckham to Lewisham.
- I do not suspect the peak services from Victoria / Blackfriars to Medway will stop at anything other than Denmark Hill (maybe Elephant if using Blackfriars); but the Blackfriars to Maidstone I suspect will be Elephant and Denmark Hill all day. Two major reasons: one, the draw on Hospitals and interchange to LO; two, the fact that not-stopping simply adds a few minutes of recovery time and the same passing time at Shortlands as you’ll catch an Orpington / Sevenoaks anyway.
- Hayes will have 6tph at peak. 2tph Victoria, 4tph Charing Cross. All Charing Cross peak services are fast to/from Ladywell. So only half-hourly at Lewisham, which is in my view a huge shame. Same for the Sidcup line. There will be in 2022 no Sidcup terminating services. All 10tph run at least to/from Crayford; and only the 2tph to Victoria run via Lewisham! The 4tph to both Cannon Street and Charing Cross are fast from Hither Green; although it is expected the Cannon Street services will stop at New Cross.
