The Bakerloo line station at Warwick Avenue used to (I think it's been
covered over now) show a map of the line which extended to a never-built
extension in south London. It was wishful thinking rather than an
attempt to confuse passengers (or invading Germans).
In 1938 the Underground temporarily turned over production of its route
diagram from Henry Beck to Hans Schleger. Schleger's first published
version, that July, wrongly showed the Central Line extension from
Liverpool Street already open as far as Mile End. As it turned out,
of course, none of the extension was opened until 1946, and Mile End
was never a terminus.
