Mugby junction, the extra Christmas number of All the year round [Annotated]

Mugby Junction was a set of short stories by Charles Dickens written in 1866. It was first published in a Christmas edition of the magazine All The Year Round. The entrance to the Clayton tunnel near Brighton, as seen from the north.

It includes the famous ghost story The Signalman 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.
