Runs empty from Wembley LMD to South Ruislip as 5V35, forms 2V35 to
Paddington, 2M30 back to West Ruislip, then 5H43 back to Marylebone,
though that's only part of the unit's diagram for the day.

The trains in question are only worked by Aylesbury drivers, and I
believe they need a Guard as well.

Yes, there was a guard. All he did was to walk through the train just
before departure on each leg to check that we all knew where it was going.
Everyone did -- that's why we were on it.

I had thought the plan was to divert a couple of the existing
services to Oxford. The xx48 from Marylebone would be an obvious
choice: it terminates at Bicester, rather than the more natural
Banbury, and doesn't connect with anything. However the matching xx18
service which would be the other one to send to Oxford does have a
connection at Bicester North and is also sometimes extended to
Banbury or Stratford (even though it would be better to extend the
xx48).

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.

What use is a diversionary route that only a fraction of the drivers
have the route knowledge for?

More use than one that nobody has knowledge for.
How big in numerical figures is the "fraction" ? Are there also e.g.
freight drivers from somewhere else who could act as pilots if
necessary ?

When you schedule the diversions, you roster drivers who know the route...

fGW examples include only Exeter drivers sign via Honiton, only Swansea
sign via Barry, Swansea *don't* sign via Newbury, etc.

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.

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.

October of which year? The Chiltern website says the current timetable
is valid until this December.

Bearing in mind that, to keep the route on their card, a driver needs to
drive over it at *least* every six months, and Chiltern run over it
approximately 260 days a year, that gives a theoretical maximum of 130
drivers who can sign it...assuming you have a different driver every day.

Chiltern has approximately 300 drivers, so short of running two or three
trains a day to/from Paddington (which there isn't the stock for, let
alone paths), it's impossible for the entire complement to sign the route.

With the route being limited to two trains per hour each way due to the
single line, it's just as easy to change drivers at West Ruislip and
implement stepping back.

Cheers,

Barry
