Lockers change lives for homeless

Everything Fabio Ferreira Silva owns fits inside one of the 12 bright-yellow lockers in front of Lisbon's riverside Santa Apolonia rail station.

Silva and other homeless people use the metal cabinets to store their belongings, which they once dragged around the hilly, cobblestone streets of the Portuguese capital in boxes, bags or shopping carts.

"These lockers are very important," he says holding open the door to his locker, where he stores a blanket, clothes, a mobile phone charger, toiletries and personal documents.
