Mugby Junction" is a set of short stories written in 1866 by Charles Dickens and collaborators Charles Collins, Amelia B. Edwards, Andrew Halliday, and Hesba Stretton. It was first published in a Christmas edition of the magazine All the Year Round. Dickens penned a majority of the issue, including the frame narrative in which "the Gentleman for Nowhere," who has spent his life cloistered in the firm Barbox Brothers & Co., makes use of his new-found freedom in retirement to explore the rail lines that connect with Mugby Junction. Dickens's collaborators each contributed an individual story to the collection.Mugby Junction includes the famous ghost story "The Signal-Man" concerning a spectre seen beside a tunnel entrance. The signal-man of the title tells the narrator of a ghost that has been haunting him. Each spectral appearance precedes, and is a harbinger of, a tragic event on the railway on which the signalman works. The signalman's work is at a signalbox in a deep cutting near a tunnel entrance on a lonely stretch of the line, and he controls the movements of passing trains. When there is danger, his fellow signalmen alert him via telegraph and alarms.Three times, he receives phantom warnings of danger when his bell rings in a fashion that only he can hear. Each warning is followed by the appearance of the spectre, and then by a terrible accident.
