I think that there was a suggestion, round about 1870, that
Farringdon be such a thing. Didn't the Circle Line have broad gauge
tracks, as well as standard, at one time?

The only thing I remember about the Abercrombie plan of 1943 was that
it proposed to abolish Waterloo.

I liked its plan to have aeroplane landing strips on the roof of all
the main line terminals, for the taxi planes bringing people into
town from the long-haul airports.
