The altered signal

An original fiction passage set in the nineteenth century.

At the signal cabin, the railway clerk received word that a cart had overturned beside the cutting. The note said the rails appeared clear. The express was due in nine minutes. His supervisor told him to keep the signal open; delaying an important train on the word of a farm boy would invite a complaint.

The boy remained at the foot of the steps. He said one wheel had rolled farther than the cart itself. He had not seen where it stopped. The clerk looked through the cabin window, but the bend hid the cutting. His supervisor repeated that the note reported clear rails. The clerk noticed that it reported only what had appeared clear.

He put the signal to danger. The supervisor began to protest, then stopped when the approaching engine sounded its whistle. They walked to the cutting together. Beyond the overturned cart lay a broken iron rim across one rail. The boy had stayed beside it, waving his coat.

The express stood at the signal for seventeen minutes. Its passengers complained, and the supervisor recorded the delay in his book. Beneath the entry, he added the obstruction that had been removed. The clerk read both lines before returning to the cabin. He had not kept the timetable. He had made certain there was still a train able to follow it.

“The clerk’s decision to stop the train is shown as responsible rather than timid.”
