Slow Train Through Africa with Griff Rhys Jones ITV, 9pm
New series. The comedian makes 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 begins in the north, on a line that links the trading cities of Morocco, Algeria and Tunisia. Stocking up for his trip at a souk in Marrakesh, he boards the train for a seven-hour ride to the ancient city of Fes, and eventually reaches the Sahara - and his final destination of Tozeur.
