AVENGERS: The Gravediggers 13

Here is one of the best DiD scenes from the original The Avengers The Gravediggers.  Where spies are developing a radar blackout device to blind the West's defences. Mrs. Peel fins the spies and is captured tied to train tracks. The screenshots are  from the Desolation Angel's Damsels in Distress blog and here is the scene itself.

John Steed diverts the train and save Mrs. Peel.
