Steam Train Emerges from Tunnel in Snowy Helsinki

Thick white steam billows from a vintage locomotive as it rounds a sharp switchback curve near Kallio. Heavy snow blankets the ground and rests on the dark metal rails, against the train's deep red and black paint. The overcast sky diffuses the light, softening shadows across the frost-covered embankment. Snowflakes hang suspended in the plume of vapor, catching the pale daylight. The engine's wheels grip the icy tracks, kicking up small sprays of frozen grit. Wooden sleepers are half-buried under the winter drifts, while the tunnel mouth frames the dark interior behind the bright exhaust. One rivet glints on the boiler's side.
