It got as far as Verney Junction on it way to - where? Other mainline
attributes (not pretensions because they worked) was a Pullman car
from Verney Jct to the city.

To the Chairman's family seat, perhaps! There was a branch from Verney
Junction to Buckingham, which might have been in their minds. They might
even have had in mind a Chiltern Railways-like route to Oxford?

BTW there was a Pullman service from Chesham, too. Once the S stock is in
use the good folk of Chesham will think themselves spoilt just to be able to
get a seat on the train!
