The problem with the route by way of Claydon is that it only provides
a very indirect route to Milton Keynes. There is no easy way of
connecting it to Banbury. The route by way of Verney Junction, plus a
new curve, provides through routes to Banbury and Milton Keynes.

Having both gives the residents of Metroland living north of Harrow
great increased travel opportunities.

But if that were the main objective - and I'm not suggesting it isn't a good
idea - it could be achieved much more easily with the Croxley Link. Then you
could run the following services:

Baker Street to Watford Junction via Moor Park (Met)
Baker Street to Chesham (Met)
Cut out all Met Amersham services - basically diverting these to Watford
Junction
Marylebone to Aylesbury Vale Parkway via the Met line (Chiltern), serving
Amersham
Aylesbury Vale Parkway to Watford Junction (Chiltern).
