Wonderful railway-themed episode with some stylish villainry. Also a great opening which plays with our expectations of what kind of story it's going to be: first a vaguely Sweeneyish chase through a marshalling yard, then the suggestion of a Sapphire-and-Steel-esque timeslip at the deserted station. That's Michael Nightingale on the run btw (the bank manager in Carry On Cowboy and the stand-in Supervisor in Dance of the Dead).
The bride-and-groom villain couple are great: Isla Blair (Isabella in The King's Demons) with her callous humour and Drewe Henley seeming all the more evil in his immaculate morning dress.
John Laurie (third appearance) is fun as an obsessive railway fanatic. It's amusing when he attacks the gun-toting Drewe Henley for shooting up his prized signalbox. But, like other recent supporting characters, he performs a pivotal action in saving Mrs Peel from falling out of the train door during the ensuing fight.
Rather a nasty anti-Harold Wilson joke at the end. Sure, I doubt that Steed and Mrs Peel would be Labour voters, but it seems odd that the script goes so far out of its way to insult him, particularly when American viewers, usually well-catered for by this series, wouldn't understand the 'raincoat' reference.
Also seen: Tim Barrett (who Reggie Perrin tricks into calling C.J. a slimy creep). Richard Caldicot[t] who I think is the navy representative at Six's debriefing in Many Happy Returns.
One of the thugs in the opening chase is apparently played by a Jonathan Miller. It can't be him surely? IMDB says it's him.
