Dickens survived Staplehurst in June 1865. Ten people died. He spent hours among them. He was never quite the same. He died five years later, on the anniversary of the crash.

This story was written within months of it.

A signalman is haunted by an apparition that appears at the mouth of his tunnel in warning before each fatal accident on the line. He cannot decode the warning. The narrator, listening, cannot either. The information arrives. It cannot be used.

That’s the horror Dickens has identified: a warning without meaning is not a warning. It is just a horror, repeated, and the only thing it tells you is that something is coming. Not what. Not when. Not what to do.

He was writing from experience. He knew what it was to receive information in the moment before impact and be unable to act on it.

Some knowledge arrives too late to be useful. That is still knowledge.
