I see they make reference to this "unknown" station, or something like
that.

Seems the taggers know all about it though and can find their way inside.

You may have missed it at the time, but a few years ago graffiti 'artists'
wrecked a central area deep tube station during Christmas Day, apparently
despite all the supposed continuous CCTV surveillance they'd just walked the
few miles down the tracks from one of the portals.
