Transnet has issued a tender for a leasing company, a step the state-owned rail and ports operator says will open third-party access to locomotives and wagons on South Africa's freight network.

The tender marks the most concrete move to date in Transnet's rolling stock reform programme. A dedicated leasing vehicle would give private operators — mining companies, hauliers and new entrants holding access slots on the corridor network — a route to traction and wagons without depending on Transnet Freight Rail's own constrained fleet.

The state utility's locomotive availability has weighed on tonnage for years. Coal exports on the Mpumalanga-to-Richards Bay line, the network's highest-value corridor, have repeatedly missed contractual volumes, and iron ore exporters on the Sishen–Saldanha route have pressed for greater operational control. Third-party access, first outlined in the government's rail economic policy shift, requires operators to source their own rolling stock; a leasing company addresses the capital barrier that has slowed entries.

The tender invite follows earlier reform milestones: the network statement setting access rules, the licensing of independent operators, and pilot agreements on select corridors. Transnet frames the leasing company as the mechanism that converts those access rights into runnable services.

The operator has not disclosed the leasing company's capital structure, the size of the initial fleet, or the closing date for bids in the publicly circulated announcement. Bidders will presumably need rail-sector asset management credentials and Black Economic Empowerment compliance, standard requirements in South African state procurement, though the tender documents govern the specifics.

Industry observers will scrutinise two questions. First, whether the leasing fleet adds net capacity or reallocates existing locomotives already short in the market. Second, whether private operators can secure maintenance depots and crews — the practical constraints that have complicated access pilots elsewhere on the network.

Transnet says the leasing company forms part of its broader turnaround plan, under which it aims to recover volumes lost to road haulage and restore export corridor performance.

The utility expects to evaluate bids and appoint an operator for the leasing company in subsequent procurement stages, with the first leased rolling stock projected to enter service once contracts are finalised.
