The OO scale 1950s railway porter calling out the train is one period station staff figure with a hand raised beside his mouth. Intended for supply unpainted in grey resin, he is ready for your chosen finish. The painted station scene is an illustrative example; its scenery is not included.
Position him near a waiting train, at the platform entrance, or among passengers listening for their departure. His clear calling gesture gives a small station a recognisable moment of railway activity without needing a separate prop.
Let your platform scene announce that the next train is on its way.
