South Africa’s push to revive freight rail faces a two-sided challenge: Transnet must get more cargo moving on its existing network while preparing for private operators to compete for rail business.

A R6.6 billion ($401.7 million) agreement with US-based Wabtec is aimed at addressing one of the immediate constraints — the performance of Transnet’s locomotive fleet.

The contract covers the state-owned logistics group’s Class 43D and 44D locomotives, which haul export commodities, containers and general freight.

Their reliability matters to mining companies, exporters and other businesses that depend on predictable transport to move goods through South Africa’s logistics chain.

The agreement arrives as Transnet attempts to recover from years of operational difficulties, including locomotive shortages, theft of railway cables and tracks, and limited resources. In 2025, Transport Minister Barbara Creecy approved rail network access for 11 private firms, ending Transnet’s longstanding monopoly on rail operations.

Private competition raises the pressure

Opening the network to private operators changes the environment in which Transnet must rebuild its performance. The state-owned company remains central to South Africa’s freight system, but improving service reliability is increasingly important as other companies gain opportunities to move goods by rail.

The Wabtec agreement is one part of that operational challenge. Under the long-term arrangement, Wabtec will supply components and technical expertise to Transnet Engineering, alongside predictive maintenance capabilities for the two locomotive classes.

The package includes Expert-on-Alert, Wabtec’s digital condition-monitoring platform. The technology is designed to help identify equipment problems, improve maintenance planning and shorten turnaround times, potentially allowing locomotives to spend more time in service.

Beyond repairs and spare parts

The partnership also includes technical collaboration, knowledge transfer and localisation initiatives. Transnet expects these measures to develop industry skills and strengthen domestic rail capabilities, supporting the longer-term sustainability of the sector.

For Transnet Engineering chief executive Bessie Mabunda, the agreement forms part of the company’s “reinvent for growth” strategy. She said improving the availability and reliability of the Class 43D and 44D fleets would support freight recovery, service delivery and South Africa’s logistics competitiveness.

The commercial test will be whether better maintenance translates into more dependable freight services.

A more reliable fleet could help Transnet serve exporters and other cargo customers more effectively, but the agreement alone does not resolve the wider constraints affecting the network, including infrastructure theft and resource shortages.

As private participation expands, Transnet’s ability to restore operational performance will remain central to the recovery of South Africa’s freight logistics system.
