6. Many tube stations were used as air-raid shelters during the Second
World War, but the Central Line was even converted into a fighter
aircraft factory that stretched for over two miles, with its own railway
system. Its existence remained an official secret until the 1980s.

That would be why it's mentioned in the 1947 "A History of London
Transport", then.

Typo: that should have said "1974".

I have here a 1971 reprint of "The story of London's Underground", published
in 1963, second revision 1969. It includes a photo of the Plessey
underground factory as plate 35.

Did some aspect of its work remain secret until the 1980s? I must admit, I
can't imagine why it would have done. It's not as if they were making
equipment for Bletchley Park (or were they)?
