The latest iteration of the October timetable has been uploaded
into ITPS, so is now available in journey planners, and it's a
fairly major recast in the off-peak!

Northbound from Marylebone:

xx.05 - Oxford Parkway (fast to Haddenham & Thame Parkway)
xx.10 - Birmingham Moor Street (High Wycombe, then fast to Banbury)
xx.13 - Aylesbury via High Wycombe (fast to Gerrards Cross)
xx.16 - High Wycombe (Wembley Stadium, South Ruislip, Gerrards
Cross, Beaconsfield)
xx.27 - Aylesbury via Amersham
xx.35 - Oxford Parkway (fast to High Wycombe, then Bicester Village)
xx.40 - Birmingham Snow Hill (Bicester North, Banbury...)
xx.43 - Banbury (fast to Gerrards Cross)
xx.46 - Gerrards Cross (stopper)
xx.57 - Aylesbury Vale Parkway via Amersham

The xx.10 Birminghams are the current xx.15s, but with an
additional call at High Wycombe; xx.13 is the current xx.21; xx.16
the current xx.25(ish); Mets return to xx.27 and xx.57; xx.40 is
the current xx.45 minus the High Wycombe call; xx.43 is the current
xx.48 and xx.46 is the current xx.52.

Thanks, that's interesting. That leaves the xx.05 as being the
current xx.18 and the xx.35 is new.

Hopefully the xx.43 will connect with the xx.10 at Banbury, although
presumably it will sometimes be extended to Stratford and I don't
know how the timetabling would fit for that. The xx.40 appears to
lose the Bicester North connection that the xx.45 has, but it's not a
very good connection and Banbury is a better place to change anyway.

Yes, eg the 1143 arrives Banbury 1302, the 1210 calls at Banbury 1307.

The only through trains to Stratford are 0618, 1824, 2043. No through
off-peak services. There will be a connection at Leamington every 2
hours from the xx10. This will actually be a bit quicker than the
current 3-hourly through train.
