Railway upgrade to cost R1.5 trillion, Transnet says: South Africa’s plan to widen the country’s railways would cost as much as R1.5 trillion ($110 billion), take years to implement and require the cooperation of neighboring nations including Mozambique and Botswana, according to state transport company Transnet SOC.

Africa’s most industrialised economy should start to convert its 20 000 kilometers of track to standard-gauge rail size from the narrower Cape gauge, Transport Minister Dipuo Peters told reporters on Tuesday. That would bring the network in line with about 60% of other countries, boost capacity and reduce transportation costs, she said.

Transnet Acting Chief Executive Officer Siyabonga Gama said that while the company supports a move to standard gauge, the policy “needs further investigation” to determine its viability.

“We did an assessment and we found out that if we had to create 15 000 kilometers of track, we would need up to R1.5 trillion,” he said in an interview after the announcement. “It would be a very expensive exercise.”

Transnet owns and operates railways, freight trains, ports and pipelines in South Africa, and is responsible for the transportation and export of commodities such as coal and iron ore. The company plans to expand in Africa and the Middle East, and wants 25% of revenue to come from outside its home market by 2025.

“Our trains need to go to Mozambique, Zimbabwe, Botswana, to Namibia, those countries would also need to work on that gauge,” Gama said. “Every country will need to start moving toward that direction. All I am saying is it will take a very long time, beyond my lifetime.”
