Rulfo’s photos illustrate the conflict between Mexico City and the means of transport that had changed the way it functioned. Streets full of automobiles cut off by the passage of locomotives, views of tracks and pedestrians crossing them, freight cars, makeshift housing set up amidst the trains, enormous marshalling yards, warehouses, smoke, women carrying hot water to wash clothes in, tenement courtyards in the railroad neighbourhoods…. Rulfo’s images show another of the worlds he knew so well: Mexico City.
