Colas Rail, a prominent provider of rail infrastructure services with over 35 years of experience in High-Speed lines, was commissioned by Morocco’s railroad operator, ONCF (Office National des Chemins de Fer), to spearhead the design, construction, and testing of Africa’s inaugural High-Speed Line. My primary task involved crafting a compelling promotional teaser video centered around the dedicated personnel at the base station. Immerse in the worksite for five days, I seized the opportunity to initiate the creation of a photographic archive, emphasizing industrial portraits of laborers.
