London TUBE Horror

by Abe
(Liverpool UK)

Late one night toward the end of my conscious period, I came across a film about a commuter who got locked into the Tube system, encountered homeless and ultimately a deranged 'zombie' character who seemed to be the result of a mad scientists secret experiments in an underground lab. I also seem to remember a sort of rape scene taking place. There was a boss piece of dance music that played over the end credits.

This movie has sort of haunted me ever since and I need to own a copy so I can 'exorcise' this feeling stuck in my head!

Anyone know what it is? I'd love to know...
