The tendering for the feasibility study for the construction of the multibillion dollar Trans- Kalahari railway line – connecting Botswana’s Mmamabula coal field to the port of Walvis Bay in Namibia – is expected to start before the end of this year, Namibia’s National Planning Commission (NPC) permanent secretary, Leevi Hungamo, said. “The tender process for the feasibility study will start this year and the report will be ready next year. The two governments are still working on logistics and setting up the project management office that will spearhead the project,” he said.
