Upgrading works for Cochabamba – Arani railway line. Preliminary environmental study and Technical, Economic, Social and Environmental Studies. Section length: 64.5 km.
The project involved the preliminary environmental study and the Technical, Economic, Social and Environmental Studies for the upgrading works of the railway line connecting Cochabamba to Arani, as the existing line runs through an undulating topography from Cochabamba to Caluya and through flatland for the rest of the section, with slight slopes and long straight stretches. It has a 3 to 5-m-wide-platform, made out of ballast obtained in different quarries along the route. The meter gauge rails weight less than 60 pounds per yard.
