South Africa’s move towards an open-access rail model marks one of the most significant shifts in the country’s freight logistics landscape in decades. Allowing private operators to run services on designated freight corridors introduces competition in train operations while the state retains responsibility for the underlying infrastructure.
The Transnet Rail Infrastructure Manager (TRIM), established to manage the national rail network infrastructure, is central to this transition.
This reform has the potential to unlock capacity, improve reliability and stimulate long-overdue investment, but only if the physical network is ready for the increased demand it will need to support.
Physical network still lagging
From an institutional and regulatory perspective, the foundations for open access are taking shape. Mechanisms for allocating slots, managing access and ensuring fair participation are emerging, creating a more transparent, commercially oriented environment.
However, readiness on paper does not equate to readiness on the ground. The country’s physical rail network has endured years of underinvestment, maintenance backlogs, security breaches and capacity constraints.
Signalling remains outdated across many corridors, traction power is inconsistent, and rolling stock availability remains insufficient to support rising throughput. While institutional arrangements are being developed for multiple operators, the infrastructure is not yet ready at scale.
Open access will only succeed if modernisation accelerates and investment in track, signalling, electrical systems and rolling stock support keeps pace with operator growth.
Pressure points to intensify
As new operators enter the network, pressure will intensify across several critical areas. Signalling and train control systems need urgent upgrades to ensure safe, reliable operations.
Power infrastructure must also be stabilised and expanded to support more locomotive movements. Rolling stock shortages could worsen if supply fails to keep pace, while demand for maintenance facilities, components and refurbishment capacity is likely to grow.
These are not isolated challenges; they are interconnected. A modernised signalling system is ineffective without reliable traction power, and additional locomotives and wagons add little value if maintenance capacity cannot support them. The entire system must develop together.
Investment ahead of demand
The shift to a multi-operator environment fundamentally changes how engineering and maintenance partners must plan. Under a single-operator model, suppliers often aligned their investment cycles with one entity’s procurement patterns. That approach is no longer sufficient.
What is needed now is flexibility, responsiveness and local capacity. Engineering partners must invest in standardised components, strengthen technical support and shorten turnaround times. Operators will need reliable maintenance and engineering support throughout their assets’ lifecycles, and suppliers must be ready to meet that demand.
This is also an opportunity to reinvigorate local manufacturing. For years, limited investment in rail infrastructure has weakened South Africa’s domestic rail supply chain. Open access can help reverse this trend if suppliers invest early and decisively.
Collaboration beyond slot allocation
Slot allocation determines when and where trains can run, but collaboration goes deeper. Infrastructure managers, operators, original equipment manufacturers and engineering partners must share information, plan maintenance jointly and coordinate investment decisions.
If suppliers are only brought in when equipment fails or procurement begins, the system becomes reactive rather than strategic.
Working together from the outset allows us to design fit-for-purpose solutions, plan spares and maintenance capacity, and ensure that assets are supported throughout their lifecycles. A fragmented approach will undermine the very benefits open access is intended to deliver.
South Africa’s freight rail growth ambitions are achievable, but not at the current pace of modernisation. Reaching them will require accelerated investment in network capacity, signalling, traction equipment, rolling stock and maintenance. Without this, the system will struggle to absorb additional operators and volumes.
The biggest risk
If infrastructure investment does not keep pace with operator growth, the benefits of open access will not fully materialise. Increased traffic on an already stressed network can heighten safety risks, reduce reliability and accelerate wear. Investment in locomotives and wagons must be matched by investment in the infrastructure that enables them to operate efficiently.
Despite these challenges, open access can help rebuild South Africa’s domestic rail supply chain, stimulate investment in locomotives, wagons, signalling, electrical refurbishment and local manufacturing, and restore the country’s position as a leader in rail engineering.
If we modernise decisively, collaborate meaningfully and invest ahead of demand, open access can expand freight volumes and reshape the future of South Africa’s rail sector for generations to come.
