Monica Dickens. In 1915, author Edith Siepen says the soup originated in France, probably a misunderstanding due to the early French name in The Modern Cook. Windsor and/or Brown Windsor has been associated with the British Railways by a number of authors, although historians have had trouble verifying it ever existed. Malcolm Timperley, a researcher in the National Railway Museum's library and archives, reported that their team specifically researched the existence of Brown Windsor soup in British dining cars. After checking scores of menus dating back to the nineteenth century they failed to find any mention of it. Nevertheless, according to author Paul Spicer, Brown Windsor was popular on British railways, and "was often said to have built the British Empire". Author Jane Garmey, writing about it in 1981, said Brown Windsor was "continually served by British Railways in their dining cars", and from her childhood memories she "assumed it was the only soup that could be served on a train" due to its ubiquity. Fictional barrister Rumpole of the Bailey mentioned eating it on the Great Western Railway in a book of short stories dated 1978, although Quinion questions whether this is an endorsement of the soup, "the extract confirms that the soup was at one time a staple of the restaurant menus of British Railways," in Quinion's view. In popular culture The magazine The Poke advertised a satirical can of Brown Windsor soup as part of a "Jubilee Collection," available for about £40, complete with silver spoon and reportedly made "directly from the sewage outflow of Windsor Castle." Brown Windsor soup is identified in the film Carry On Regardless (1961) by Kenneth Connor as the dish he is splashed with having knocked over a waiter's tray on a train and in Carry On Abroad (1972) by Kenneth Williams in a scene in the hotel's restaurant, where the soup is mistakenly referred to as "Brown Bristols" by the Spanish hotel manager, played by Peter Butterworth. In an episode of The Goon Show entitled "The Macreekie Rising of '74", Brown Windsor soup is used as a weapon and mocked as "more deficient in calories than Scots porridge" by the impressively stout Neddy Seagoon. In Rumpole of the Bailey, episode "the Alternative Society", Rumpole has an inner monologue while riding a train in which he yearns for a real old fashioned railway lunch starting with "a touch of Brown Windsor soup",
