- Mauritanian Iron Train - Perhaps the longest train in the world
It is a freight train that has been operating since the 1960s and connects the enormous iron mines of the city of Zouèrat , located deep in the Sahara, with the port of Nouadhibou , a town on the Atlantic coast in northern Mauritania.
The iron train has an impressive number of wagons, around 200, and is between 2.5 km and 3 km long depending on the quantity of ore transported.
It travels on a single 704-kilometer track that starts from the mines inland and ends at the coast.
Typically, during the day, there are 6 trains in total , 3 travelling loaded from the mines to the coast, and 3 travelling unloaded back to the mines.
