Mauritania - The perpetual roar of carts on rusty tracks that disappear on the desert horizon. The bleating of goats suffering from heat and thirst, together with young people on a journey dreaming of Europe. Freight wagons with Bedouins and strong mint tea. The train, carrying tanks full of water and fuel, cuts across the desert landscape from the endless horizon of sand. In the mud huts along the tracks people live a humble life bordering on poverty. The water and fuel tank is the fundamental unit of measurement for survival. The train is the main axis of life for the Bedouins who take a breath in the shade of the heat and in the surroundings of tranquility.
