In the middle of the night, a train is blaring its horns, announcing its arrival at a wayside station. A man, casually walks across the tracks and takes position on a tiny pedestal. In his hand, a blazing torch and a hoop of wire with a pouch that contains a metallic ball. He then waits for the train to come straight at him.
How all trains were kept apart in the old days, by "token" system.
I hope AU members will enjoy these stunning pictures as much as I did.
