So I guess your options are
getting a track/tunnel maintenance job or hiring Aldwych station -
which is frequently used for filming.

Gee, I'm not the rich (to hire entire station) or strong (to do manual
work)...
Well, let's hope situation will change in the future!


The two best websites for photos & descriptions of all these stations
a
www.abandonedstations.org.uk
and
www.underground-history.co.uk

Those website are amazing, but I want to see it with my own eyes!
