New series which sees comedian Griff Rhys Jones make five train journeys taking in the spectacular sights of Africa, travelling to unexpected places in deserts and forests, villages and cities, and finding out how the railways are used today. He kicks off tonight in the north, on a line that links the trading cities of Morocco, Algeria and Tunisia. The seven hour train ride will take him to the ancient city of Fes, and eventually reaches the Sahara - and his final destination of Tozeur.
