In terms of the Walvis Bay-Ndola-Lubumbashi Development Corridor scheme (Wbnlc), Zambia has reopened discussion on building a rail link between Livingstone and Namibia. The line envisaged would pass through Katima Mulilo (on the Zambian border at the Zambezi crossing) in the Caprivi Strip and join the Namibian system at Grootfontein, railhead of a branch from Otavi on the Walvis Bay-Tsumeb line. The Wbnlc authorities reportedly envisage setting up 'industrial clusters' along the route, making an 'economic engine' for the region. Scoping studies on mining, agriculture, tourism and infrastructure development are reportedly in progress along the corridor. Zambia's commerce, trade and industry permanent secretary Stephen Mwansa revealed at a recent Wbnlc seminar in Lusaka that the country is committed to the construction of the railway, saying: "We would like to take this opportunity to urge our Namibian counterparts to urgently consider bringing the railway line up to Katima Mulilo in the shortest possible time for our countries and their people to benefit."
