The new station building was built just outside Osøren hotel. Immediately beside the hotel was the turntable for the railway engines and the coal pit where they loaded the coal. This led to the first “pollution case” in Os; the hotel owner complained of considerable nuisance from smoke and noise from the station and the court agreed with him.
Today the turntable is placed below the asphalt, but the station area, with the station building, the engine hall and the engine workshop, is unaltered. The engine hall, which was built in an open iron column structure, was added to and extended some years after the opening of the station. The Os railway transformed communications in the Bjørnefjord communities. Suddenly the town was only a few hours away, and the transition from sea to land belonged to one of the greatest chapters in Norwegian transport history.
