Abandoned signal boxes at Woodside Park.

Which reminds me, is what looks very much like a signal box on the
Circle (etc) lines at Liverpool St still in use? If not, when did it
cease to be used?

It's still a signal box, but the signal control centre located at Baker
Street now controls the signals and points. It's been 'de-personed' for
quite a while, Farringdon signal cabin used to control it till that was also
taken over.
