Colas Rail, a distinguished provider of rail infrastructure services with over 35 years of expertise in High-Speed lines, consistently secures contracts from Morocco’s prominent railroad operator, ONCF (Office National des Chemins de Fer). Among their diverse ongoing endeavors, Colas Rail takes charge of the inaugural African High-Speed Line and undertakes the crucial maintenance and doubling of the Marrakech-Settat line. Additionally, their reach extends to urban landscapes as they are entrusted by the cities of Casablanca and Rabat-Salé to construct the infrastructure for their respective tramway lines. My journey crisscrossed Morocco, traversing from Tangier to Marrakech and back, capturing their operations on film. The resultant promotional video graced corporate gatherings and railway exhibitions, showcasing Colas Rail’s impactful contributions.
