A 1,500 km-long railway project between Niamey, the capital city of Niger and Cotonou, the capital city of Benin has been green lighted by the authorities of the two countries and construction will begin on March 2014  [fr]. Francois Ndiaye in Niamey unpacks the set up of the financial agreement  [fr] that includes multiple stakeholders and will be overseen by the investment group Bolloré  [fr]. Benoît ILLASSA in Cotonou wonders why private investing groups from either Niger or Cotonou were not selected  to pilot such projects. The projected budget is set at 100 billions CFA (about 2 billions USD). The railway should extend in the future to three other capital cities of the west african region : Abidjan, Ouagadougou and Lomé.
