ACROSS THE SAHARA

The treasure lies in Mauritania, West Africa. The people here shovel 15 million tons of iron ore out of the mountain every year. The longest and heaviest train in the world transports the raw material from the interior to the coast. His wagons are lined up for a full three kilometers. Since 1963, the train has transported iron ore and courageous passengers 650 kilometers through one of the largest deserts in the world: the Sahara.
