Transnet: When the Railway Stops, the Mine Stops

Transnet’s failure is a direct tax on every South African export. This story covers the state monopoly structure, the locomotive procurement scandal, the rail collapse, port congestion, private participation reform and what it costs the economy — part of the South Africa Company Stories hub.

Why does freight rail matter so much?

Because South Africa’s exports are heavy and distant from ports. Coal from Mpumalanga, iron ore from the Northern Cape, manganese, chrome and containerized goods all need bulk transport over hundreds of kilometres, which only rail can do economically.

The dedicated export lines — the coal line to Richards Bay and the iron ore line to Saldanha — were engineering achievements, purpose-built heavy-haul railways moving enormous tonnages efficiently.

When they underperform, the tonnage does not move. Mines with product and buyers cannot ship it, and the revenue is lost permanently rather than deferred, because commodity sales are contracted to delivery windows.

What was the locomotive scandal?

A procurement of over a thousand locomotives that became the centrepiece of state capture findings at Transnet, involving inflated contract values, irregular processes and payments to intermediaries documented by judicial inquiry.

The operational consequence outlasted the financial one. Contractual disputes with the Chinese manufacturers left Transnet unable to obtain spare parts for a large portion of its fleet, so hundreds of locomotives stood idle while the railway lacked traction.

Resolving the dispute took years and required negotiating with suppliers whose original contracts were tainted, which is legally and politically complicated even when the operational need is urgent.

How bad did rail performance get?

Coal export volumes on the Richards Bay line fell to levels not seen in decades, well below both the line’s design capacity and the volumes mines were producing. Iron ore, manganese and general freight suffered comparably.

The causes compounded: insufficient available locomotives, wagon shortages, cable theft disrupting signalling and forcing manual train authorization, derailments from track condition, and loss of experienced operating staff.

Cable theft deserves specific attention. Organized theft of signalling and overhead cable has affected hundreds of kilometres of line, and each incident stops trains until repair, which in some corridors has been near-continuous.

What happened at the ports?

Severe congestion, particularly at Durban, driven by equipment breakdowns, crane availability, weather disruption and inefficient terminal operations, producing ship waiting times among the worst in the world in global port rankings.

Importers and exporters paid demurrage, missed shipping schedules and rerouted cargo, and the cost fell throughout the economy since virtually all trade passes through these ports.

Container terminal productivity became a national issue, and the response has been to bring in private terminal operators through partnerships, beginning with a partial concession at Durban Container Terminal.

What is the private participation reform?

Opening rail network access to private train operators, concessioning port terminals to international operators, and separating infrastructure ownership from operations so that competitors can use the network on equal terms.

Third-party access to rail is the most significant change: private operators running their own trains on Transnet track, paying access fees, is the model that revitalized freight rail in several countries.

Implementation requires an access regime, tariff framework, capacity allocation rules and a network in sufficient condition to be worth using, which is why progress has been slower than announcements suggest.

Mining companies have been the strongest advocates, since they have product they cannot ship and would willingly fund rolling stock and even infrastructure to move it.

What is the road freight consequence?

Enormous volumes of coal and other bulk commodities moved by truck, damaging roads not designed for the tonnage, raising transport costs, increasing emissions and creating road safety problems on corridors carrying continuous heavy vehicle traffic.

The economics only work because rail is unavailable. Trucking bulk commodities hundreds of kilometres costs several times rail transport, and the difference comes directly out of producer margins or is passed to customers.

Road damage is a public cost, transferred from a failing state-owned railway to provincial and national road budgets, which is a hidden subsidy for a logistics failure.

What is the pipeline business?

Transnet Pipelines moves refined fuel and gas between coastal terminals and inland markets, including the critical corridor supplying Gauteng, which has no domestic refining capacity nearby.

It is the least troubled part of the group, with a newer main pipeline and relatively stable operations, and it is strategically essential given that South Africa now imports the majority of its refined fuel.

Pipeline capacity and terminal infrastructure have become more important as domestic refineries have closed, shifting the country from a refining economy to an import economy and changing what logistics infrastructure the fuel supply chain requires.

What is the lesson?

That logistics is not a support function but the constraint on an export economy. South African mines can produce more than the country can move, which makes rail and port capacity the binding limit on export revenue regardless of commodity prices or mining efficiency.

The second lesson concerns institutional destruction. Transnet had genuine heavy-haul engineering capability, recognized internationally, and lost it through appointment decisions, corruption and skills departure within a decade.

The third is about the sequence of reform. Private participation is now proceeding because the failure became severe enough to overcome institutional resistance, which is an expensive way to arrive at a policy that was available years earlier.

Why does rail matter more than road for bulk commodities?

Because the economics are not comparable. A single heavy-haul train can move the equivalent of several hundred truckloads at a fraction of the fuel and labour cost per tonne, which is decisive for products priced globally where transport is a large share of delivered cost.

When rail capacity fails, exporters substitute trucks. That works physically and destroys margins: road transport of coal or manganese over hundreds of kilometres can consume most of the price differential that made the export viable.

It also imposes external costs. Heavy trucks damage road surfaces built for lighter traffic, raise accident rates on corridors not designed for the volumes, and shift maintenance costs from the rail operator to provincial road budgets.

What is third-party access and why is it contested?

An arrangement allowing private train operating companies to run their own services over the state-owned track, paying an access charge, rather than relying on the incumbent to move their freight.

Exporters support it because it introduces competition in the service layer while keeping the network in public hands, and because private operators can bring their own locomotives and maintenance discipline to corridors the incumbent cannot serve reliably.

The objections concern capacity allocation, safety accreditation and the effect on the incumbent’s revenue base. If the most profitable corridors are opened first, the state operator is left with the loss-making remainder and less capacity to cross-subsidize the network as a whole.

How does port congestion affect the wider economy?

Through delay costs that fall on importers and exporters who have no alternative. Ships waiting at anchor incur demurrage, containers sit uncollected, and manufacturers holding imported components must carry larger inventories to protect production.

Equipment availability is usually the immediate cause: cranes out of service, straddle carriers awaiting parts, and truck queues at gates that were designed for lower volumes. These are maintenance and procurement failures rather than capacity shortages in the underlying infrastructure.

The competitive consequence is that cargo moves elsewhere. Regional ports in neighbouring countries capture transhipment volumes, and once a shipping line reroutes a service it does not return quickly, which makes congestion a cause of permanent share loss rather than a temporary inconvenience.

Why did the locomotive procurement matter so much?

Because it combined the two failures that matter most in a capital-intensive state enterprise: money lost to inflated contracting, and operational capacity that never arrived. Locomotives ordered were not all delivered, and those delivered included units grounded by contractual and spare parts disputes.

The operational effect outlasted the financial one. A railway short of traction cannot move contracted volumes regardless of how much track it has, and rebuilding a fleet takes years of procurement, delivery and commissioning.

It also damaged supplier relationships and financing terms, since counterparties price in the risk of contracts being challenged and payments being frozen while investigations run.

What would a functioning heavy-haul corridor look like?

Consistent train departures at contracted frequency, locomotive availability above ninety percent, track maintained to design speed, functioning signalling, and terminal handling at both ends able to load and discharge without queueing.

South Africa has operated exactly this before. The coal and iron ore export lines set world benchmarks for tonnages moved per train and per kilometre, which is why the decline is a management and maintenance story rather than an engineering limitation.

Restoration therefore depends on unglamorous work — parts inventories, artisan training, cable security, condition-based maintenance — rather than on new capital projects, which is both the good news and the reason progress is slow to appear in headline volumes.

What does cable theft cost the rail network?

Far more than the scrap value taken. Stolen signalling and overhead cable halts trains on affected sections, forces manual authorization procedures that slow the whole corridor, and requires replacement material and crews that are already stretched.

Repeat theft on the same sections makes restoration futile without security, so operators have moved toward alternative materials, buried routing and technologies with no resale value — solutions that cost more up front and are the only ones that hold.

It is also organized rather than opportunistic, with scrap markets, transport and buyers involved, which is why enforcement against the trade in stolen metal matters more than guarding individual sections of line.

How do exporters plan around unreliable logistics?

By carrying more inventory, contracting road capacity as backup, negotiating volume flexibility into offtake agreements, and in some cases deferring expansion projects whose economics assume rail capacity that cannot be relied upon.

Some producers have invested directly in logistics — wagons, terminals, road fleets — which is capital diverted from mining into transport because the public network cannot be counted on.

The cumulative effect is lost national revenue. Tonnes that cannot be railed are tonnes not sold, and at commodity prices that reward volume, the gap between capacity and actual movement represents export earnings the country simply does not collect.
