South Africa's freight system has been under significant strain in recent years, with slow-moving goods placing increased pressure on road networks, transporters and the broader economy. The newly signed Rail Access Agreements (RAAs) by the Transnet Rail Infrastructure Manager (TRIM) create an opportunity to improve network efficiency, ease pressure on the roads and restore greater reliability to cargo movement across South Africa – provided the necessary supporting infrastructure is in place.
The selection of 11 private train operating companies across 41 routes and six major corridors under the RAAs marks the beginning of broader private-sector participation in the freight rail network. With the first private locomotives expected on the tracks in the second half of this year, the country will soon see whether open access can help rebuild rail capacity and ease the pressures that have affected exporters, producers, businesses and communities.
Rail depends on the fixed-asset backbone that carries goods from production points into corridors, through terminals and on to market. The first private operators are expected to add 24 million tonnes of freight capacity to the network, but that volume will place immediate pressure on the infrastructure surrounding the rail line – from the facilities that load and secure freight to the connections that move it efficiently into ports, industrial zones, agricultural regions and regional markets. To ensure this transition happens with as little friction as possible, South Africa needs the infrastructure that will enable rail access to translate into reliable freight movement.
Driving rail development with private capital
South Africa's next infrastructure challenge is to attract the additional private investment needed to make the rail backbone investable at scale. However, private capital requires more than broad economic benefits. Investors need to understand how each asset will generate revenue, how it will be used, how performance will be measured and how repayment will be protected over a long operating life.
That means de-risking projects through their structure by demonstrating current demand, providing credible evidence of future demand, and building operating models that give investors confidence the assets will continue generating returns long after construction is complete.
Infrastructure developers have a direct role to play. Public-sector reform has opened the door to private operation, but the surrounding assets will require commercial discipline if they are to attract long-term funding. The opportunity now is to use private-sector development capacity to support the state's logistics agenda through projects that are practical, measurable and financially sustainable.
This can be achieved by taking rail-linked infrastructure to market as disciplined long-term assets rather than broad development concepts. An intermodal terminal or logistics hub becomes easier to finance when freight volumes are already visible, the operating model is clear, and repayment is secured through sustained use over time. That approach gives private capital a stronger basis for participation and provides South Africa with a more credible route to building the rail backbone at the scale the economy now requires.
Establishing the model for unlocking funding
To attract the investment needed to help the public sector achieve its target of increasing annual freight rail volumes to 250 million tonnes by 2029, a stable, repeatable and bankable infrastructure finance model must be established.
GIC has already demonstrated through its work on large-scale development programmes that public initiatives and resources, supported by private capital and expertise, can drive infrastructure development when the commercial logic is sound and long-term returns are credible. This experience has shown that investors respond to projects built around real demand, clear operating models and repayment structures that remain viable over time. The same approach can now be applied to the rail backbone as South Africa seeks to fund the infrastructure needed to take open access beyond its first phase.
That level of follow-through would allow capacity to be built ahead of demand instead of reacting only after the next bottleneck has emerged. Corridors could then be strengthened in line with rising freight volumes, giving operators greater confidence to invest in equipment and plan for sustained operations. That is how rail begins to provide the consistency the economy needs as a functioning system capable of supporting long-term growth.
South Africa will only begin to realise the full benefits of these agreements when freight moves consistently enough to ease the pressure that logistics constraints have placed on the economy. A rail system capable of carrying more of that load reliably would improve efficiency, reduce delays and strengthen confidence in the infrastructure that supports trade.
