Iron Ore Train: Open Wagons vs. Passenger Carriage

SNIM, the Mauritanian iron ore mining company that operates the train, attaches one enclosed passenger carriage to the rear of the freight train on most runs. Everything ahead of that carriage consists of open iron ore wagons — deep steel containers built to carry raw ore from Zouerate to the export terminal at Nouadhibou.

On the westbound run (Zouerate to Nouadhibou, the tourist direction), the wagons are empty — they have offloaded their iron ore at the coast and are heading back to be refilled. They still hold significant residual dust and ore particles coating the walls and floor, but there is no active load.

These are your two choices: the open wagons (free or negligible cost, completely exposed to wind and dust, stars fully visible, the experience most travelers come for) or the passenger carriage (a small fee paid on the train, basic benches, partial dust protection, stuffy and crowded). Not sure which suits you? Browse our booking page to see how we set up each option.

The open wagons are approximately 10 metres long, 3 metres wide, and 2-3 metres deep — tall-sided steel containers. Once aboard, you settle into your section of the wagon with your gear, and the walls of the container block the worst wind while the open top leaves you fully exposed to the sky.

The dust is constant. From the moment the train moves, iron ore dust circulates in the air. Your mask and goggles are essential from the very first minute. Everything you bring turns a dark red-brown colour within hours. Breathing unmasked for extended periods is genuinely harmful.

In exchange, you get: the full Milky Way visible overhead for 8-12 hours in the desert night. The sound of the train across the silent Sahara. The slow dawn over the Atlantic as Nouadhibou approaches. The complete absence of civilization in every direction for the entire crossing. The iron ore dust and the stars and the cold are all part of the same package — inseparable from each other.

The wagons are described as free on the westbound run. Confirm local boarding arrangements rather than relying on a published amount. This does not include the transport, guide or logistics of an organized tour.

The passenger carriage at the rear of the train is an enclosed metal compartment with wooden bench seating. It typically carries SNIM workers commuting between Zouerate and Nouadhibou, local travelers, and occasionally women with young children for whom the open wagons are impractical.

Confirm current passenger-carriage ticket costs and arrangements locally. There is no formal booking system. A carriage ticket is separate from a guided-tour quote.

The carriage is dusty despite being enclosed. Iron ore dust infiltrates every gap. It is significantly less dusty than the open wagons, but you will still arrive coated. The benches are hard wooden planks with no padding, and the compartment becomes stuffy when full. Windows, when they can be opened, let in dust anyway.

The carriage has no formal toilet facilities. The train makes stops where passengers can step off briefly. Food and water are not available on board — the same situation as in the wagons. For most travelers who have specifically sought out the Iron Ore Train, the passenger carriage is a halfway measure that provides less comfort than expected while forgoing the extraordinary open wagon experience. It does, however, have a legitimate use case.

The overwhelming majority of travelers who come specifically to experience the Iron Ore Train should ride in the open wagons. If you have read accounts of the journey, watched footage, or researched what makes this train legendary, the elements you found — the stars, the dust, the cold, the expanse — are all wagon experiences, not carriage experiences.

The open wagon experience suits: adventure travelers comfortable with physical discomfort who prioritize authenticity; photographers who want sky access for astrophotography and landscape shots; anyone who has come specifically for this journey and wants the full version of it; and travelers in reasonable health without respiratory or mobility contraindications.

Arrive prepared — mask, goggles, sleeping bag, layers, food, water — and the open wagons deliver exactly what they promise.

The passenger carriage serves travelers who need shelter rather than immersion. Older travelers with reduced mobility, for whom climbing a high-sided steel wagon represents a genuine safety risk. Travelers with pre-existing respiratory conditions for whom iron ore dust is a medical concern even with mask protection — the carriage substantially reduces (though does not eliminate) exposure. Travelers with young children, for whom the open wagons are simply impractical. And travelers who have added the Iron Ore Train to a broader itinerary and want to tick it without the full physical commitment.

One critical note: the carriage is not a comfort upgrade in any hotel-amenity sense. It offers relief from the worst of the wagon conditions, not an alternative experience of comparable quality. Adjust expectations accordingly.

The decision comes down to a single honest question: have you come to the Iron Ore Train for the experience, or despite the experience?

If the open wagons and everything they entail — the dust, the cold, the stars, the rawness — are what drew you here, ride in the wagons. Prepare thoroughly. The experience is real and worth every uncomfortable hour.

If you are riding the Iron Ore Train primarily as a transport option between Choum and Nouadhibou, or the wagon conditions represent a genuine health or safety concern for your situation, the passenger carriage is a sound choice. What doesn't work is expecting the carriage to deliver a comfortable alternative to the wagons. It doesn't. If comfort is your priority, the practical alternative is a flight from Nouakchott to Nouadhibou — about an hour.
