another two platforms at Marylebone weren't on the agenda either...

It would appear there are three double track tunnels:

One is obviously still in use, and the other two must have been for
when there was a big freight operation at Marylebone.

I can't see any use for them now - you'd need more platforms at
Marylebone and a way of four tracking at least to Neasden.

Hmm. From a state of ignorance:
- how hard would it be to quadruple to Neasden?
I know there's spare space between the platforms at Wembley Stadium,
and IMO the potential traffic would justify quadrupling at least to
West Ruislip, if not to High Wycombe.

As I recall, Wembley and the two Sudbury stations were four-tracked (two
through lines, two platform lines), but there was only double track
between the stations. Re-instating that arrangement would make it easier
to have more stoppers at those three stations (not something Chiltern
favours), but wouldn't do much for the overall capacity.
