When I was young I was told it was to dive under an underground river.
Don't know if this is true or not.

Thinking of the geography, and if the above is true, would that be the River
Fleet, which lent it's name to the original "Jubilee Line", as it was
intended to run past Fleet St. - and off eastwards - Fleet Street deriving
it's name from such river?

Just a thought .....
