All Passengers Gone, Agent Said the Train Never Left

A young woman boards Express Train G404 on New Year's Eve, determined to prove she is not insane. Once before, she rode this train and watched every passenger vanish; the railway insisted the blizzard had canceled the service, and she woke in a psychiatric hospital, where doctors drugged and shocked her until she threw herself from a tenth-floor window. Now she is back on the same day, in Car 05, Seat 12F, beside a laborer peeling an orange. She films the crowded carriage, sends the clip to her family, and resolves to stay awake and gather proof.

Then the train enters a tunnel. Pressure crushes the car, the lights fail, and when they return, every passenger is gone. The carriage is spotless, the blizzard outside has become a colorless gray void, and the intercom answers only static. When she finally reaches her mother by phone, her mother insists the train was canceled and that stranded ticket-holders are at the station seeking refunds.

She has a ticket, a video and a GPS trail. The train keeps moving, and she means to learn the truth even if it kills her.
