I'm evidently just not that imaginative to have thought about it
already. A potential through service from Aylesbury is surely *the*
selling point of this link, is it not? I could never get myself that
excited about it beforehand, as I didn't think the benefits of there
being 'more Met line' at Watford really made the whole thing seem that
worthwhile, but as part of a wider service the proposed Croxley link
starts to look rather more attractive.

I was under the impression the plan was to make two obscure back-water
suburban stub branches into a through root and make the town of Watford more
accessible from the Met. The Aylesbury link hasn't been mentioned that
often.
