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.

If the above timetable is repeated through the day it means Aylesbury has
gained a regular London via HW service which it hasn't had for many years
but Stratford continues to lose its regular London service (I think it used
to be every 2 hours).

Travelling between Oxford and Aylesbury or between Aylesbury and anywhere
North of Banbury will be awkward unless doubling back is allowed between
Princes Risborough and HW.
