1920s Steam Train Through Foggy Scottish Highlands at Midnight

the prompt

A vintage steam train from the 1920s moves through a dense Scottish Highland fog at midnight, its headlamp cutting a yellow cone through the grey. The camera begins in a wide exterior shot tracking alongside the train as it moves, the Highland landscape barely visible beyond the fog. Cut to inside: the passenger cars are fully lit with warm amber light but completely empty. Seats are set for passengers, cups of tea still steaming on fold-out tables, a newspaper open and held in place as if someone just set it down. The camera moves through the cars one by one, each identically abandoned mid-moment. In the last car, a single passenger sits facing away from the camera, a woman in period dress, completely still. The camera creeps forward down the aisle toward her. As it reaches the seat directly behind her, the train enters a tunnel and everything goes black. The train exits the other side of the tunnel. The last car is now empty. Her teacup steams on the table. The train continues into the fog. Cinematic gothic atmosphere, desaturated Highland palette with warm amber interior contrast, ultra-realistic fog simulation, silence punctuated only by train sounds, slow burn psychological horror aesthetic."
