I'm re-reading G. F. Fiennes autobiography "I Tried To Run
A Railway" and came across his assertion that the Bletchley
fly-over was a monument to those who did not recognise that
the railway should concentrate on a few main routes and
abandon routes which were not self-financing.

It's years since I last travelled on the WCML so I have to ask.
Does the Bletchley flyover still exist or was it dismantled?

Incidentally, a few mile west of Bletchley on the route the
fly-over was to serve lies Verney Junction, now of course
closed for decades. I was there a few weeks ago. To my
surprise the track in still in place and the station platforms
have not been demolished. Nor has the overhead bridge which,
I guess, brought in the line from Aylesbury.
