Ghosts on the Underground
" Documentary about unexplained phenomena experienced by staff and
passengers on the London Underground network. One billion people a
year descend 150 feet below London, to the tunnels and stations of the
tube, without a second thought for the thousands of graves, church
crypts, and plague pits that the tube has disrupted over its 100
years. Featuring previously unheard accounts from people who work on
the network, drivers, station staff and workers."
