12 minute short film about a railway in the country of Mauritania (western Africa) and how it impacts life of the locals.

Cool little video. The have 6 newer EMD SD70ACS's designed for use in high heat and sand environment. Looks like they have some older SD40 variants too. I like watching videos like this of RR's around the world.
