This railway line represents one of the key bottlenecks along the North–South Corridor of Iran and lies on a strategic route within international transit corridors. With its full integration, the corridor will enable the annual transit of up to 10 million tons of cargo, prioritizing transit shipments through Iran.

Iran Oston Consulting Engineers has been responsible for the design and supervision of 77 Km of infrastructure along this route, covering Sections 5A, 6, 7, and 8, as well as the connection to the Caspian Port, the main railway lines within the Caspian Port, and the pavement works along approximately 235 Km of the corridor.

Among the major engineering structures on this axis is the Sousar Rogah Bridge, which, at 2,670 m in length, is one of the largest bridges on the route.
