I was reading an edition of "London's Underground" (1) from the
mid-1960s, and it mentions three extension proposals that were ongoing
at the time. Two of these - the Victoria extension to Brixton and the
Fleet Line - went ahead (although of course the plans for the Fleet
Line changed greatly over the successive years).

The third was extending the Aldwych branch of the Piccadilly through
to Waterloo. I was aware that this had been considered as it's been
mentioned here before, and on a couple of websites, including CULG.

But what I didn't know is that, according to this book, the necessary
'powers have been granted'. That implies planning got to a rather
advanced stage. So my question : is that really the case, and what
happened that brought things to a halt?

(1) Don't have the book to hand so can't give accurate title, author
or publication date, but I can do so at a later stage if it's of help.
