South Africa’s state-owned logistics company Transnet is seeking a private entity to take over its main rail corridor between Durban and Johannesburg in a move it hopes will go a long way to improve the efficiency of the country’s largest container port.

The port and rail operator concedes that the container rail corridor, which comprises 670 km of double-track electrified rail linking the port with the inland container terminals of City Deep and Kascon, is “not performing optimally” and it lacks the money necessary to invest in the operation, according to South African media outlet Business Insider.
