Africa offers some pretty wild train trips, but the train ferrying iron ore from the mines at Zouérat to Nouâdhibou might just be the wildest. One of the longest trains in the world (typically a staggering 2.3km long), when it arrives at the 'station' in Nouâdhibou, a decrepit building in the open desert, a seemingly endless number of ore wagons pass before the passenger carriage at the rear finally appears. The lucky ones – ie most aggressive in a scrum – find a place on one of the two long benches (UM2500); the rest stand or sit on the floor. There are also a dozen 'berths' (UM3000) that are so worn out you can see the springs. It's brutally basic. It's also possible to clamber into the ore cars and travel for free. Impossibly dusty, this is only for the hardcore. Plastic sheets are essential to wrap your bags (and person), plus plenty of warm clothes, as the desert can get fearsomely cold at night, as well as food and drink.
The train leaves Nouâdhibou at around 2pm to 3pm daily. Most travellers get off at Choûm, 12 hours later, where bush taxis wait to take passengers to Atâr, three hours away. In the other direction, the train leaves Zouérat around midday and passes through Atâr at about 5.30pm.
