Paddington Railway Station is a large terminus in London, first opened in 1838. Agatha Christie referred to it again in her 1957 novel 4.50 from Paddington (alternate titles: What Mrs. McGillicuddy Saw! and Murder, She Said).
Paddington Bear is named for the station. The film clip below shows footage of the station in 1939, the year And Then There Were None was published.
