In 'the signal man short story', a significant theme is the power of perception. The signal man's perception of the apparitions and his attempts to make sense of them are central. There is also the theme of the industrial age and how it can be a desolate and isolating place. The railway setting, with its tunnels and tracks, represents this sense of a cold, mechanical world where the signal man is just a small part, yet he is haunted by things that seem beyond this ordinary world of trains and signals.
The primary character is the signal man. He's a lonely figure, working in isolation at his post. There are also some other minor characters like the narrator who interacts with the signal man and tries to understand his situation.
One main theme is isolation. The signal man is alone in his post most of the time, cut off from the outside world. Another theme could be the supernatural. The strange apparitions he sees add an element of the unknown and the spooky to the story.
