Dir: Pete Walker
Starring: Rupert Davies and Sheila Keith
After release from an asylum, an elderly couple continue their killing spree
The first four minutes of this horror are a black and white flashback to the past, and we see an opening semi-distant shot of a 4-car Southern Region EMU crossing Grosvenor Bridge in front of Battersea Power Station. There is also a later dream sequence involving Deborah Fairfax sitting inside a train compartment. The film should not be confused with the 1983 American slasher horror of the same name.
