The Last Train to Halcyon

The knock from the adjacent berth came with just enough force to rattle the thin wall between you. The sound of it threaded through the sleeper car like a warning, then settled into silence again, as if the train itself were listening for your answer.

You stay still for a heartbeat, trying to gather the edges of yourself. The berth is cramped, the air stale and too warm around your skin. Beneath the narrow mattress, the train moves with a long, stubborn pulse—steel wheel after steel wheel, a relentless rhythm that makes it hard to tell whether the distance outside is growing or shrinking. Somewhere farther down the carriage, metal gives a sharp, final click. A lock engaging. Or releasing. It is impossible to tell.

The keycard rests in your palm, worn smooth in the center, its corners bent from use. Your name—if it is your name—catches the amber light for an instant before the compartment shifts and the letters blur again. Beside it, the paper timetable feels absurdly delicate in your hands, a relic where it should not be, the handwritten warning pressing through the fold: Don’t trust the first announcement.

The intercom crackles overhead.

“Passenger in sleeper seven,” says the voice, smooth and nearly calm. “Proceed to Carriage Three.”

A wash of static rides in after it, soft enough to sound almost like breathing.

Then, more quietly: “Do not remain in locked compartments.”

You turn toward the door. The release plate is set into the frame, recessed and cold, but the indicator beside it stays red. Locked. There is another access panel low near the wall, half-hidden by the berth’s frame, where the metal casing meets the floor. The screws are old. Not decorative old—service old. The kind of panel that has been opened before, by someone who expected trouble.

From the other side of the partition, the neighbor speaks again, voice low and wary. “You sound like you’re trying to decide whether to panic.”

A beat.

“Good instinct,” they add.

The train lurches hard enough to make your shoulder strike the wall. For one sick moment the lights dim, and in that brief fall of shadow you catch something else: a strip of reflected darkness in the door’s brushed metal, a corridor beyond your berth that seems longer than it should be, lined with sealed compartments and sleeping shapes behind frosted glass.

Then the amber light steadies.

The speaker clears with a burst of static, as if the system has remembered something it was trying not to say.

“Schedule revised,” the voice says. “Carriage Three is now the transition point.”

The words hang there, neat and impossible, while the train drives on into the black. For a second, nothing moves but the rail-thrum under your bones and the faint shiver of breathing from the berth beside you. Then, from somewhere farther ahead in the carriage, another door slams with enough force to echo.

The sound travels back to you like a summons.
