South Africa's open-access freight railway now has most of its parts in place. Transnet Rail Infrastructure Manager holds and allocates the network. Eleven private Train Operating Companies hold slots across strategic corridors. Their planned operations could add up to 24 million tonnes of annual freight capacity, according to government.

The date attached to that capacity is the part worth reading carefully. Government expects the main operations of the 11 operators to begin from 1 April 2027. Some operators have targeted earlier starts, but the working assumption in the current reporting is that regular commercial traffic builds through the 2027/28 financial year.

For anyone running a South African supply chain on an April to March cycle, that means the budget you approve in February 2027 is the first one where rail is a live option on some corridors, and the budget you are building now is not.

The size of the gap

Rail moved approximately 160 million tonnes in the last financial year, up 5.5% year on year, according to President Cyril Ramaphosa in March. Government's target is 250 million tonnes annually by 2029.

Set 24 million tonnes of new private capacity against a 90 million tonne gap and the arithmetic is plain. Private operators close roughly a quarter of it, assuming every allocated tonne turns into a moved tonne. The rest has to come from Transnet Freight Rail recovering its own volumes on infrastructure that is being rehabilitated at the same time.

Track access alone does not produce trains. New entrants also need locomotives and wagons, and Transnet has issued a request for proposals to establish LeaseCo, a rolling stock leasing company serving domestic and regional operators. Until LeaseCo or something like it is running, every new operator has to assemble a fleet before its first train moves. That is the largest barrier to entry in the reform.

Where the money is coming from

The financing behind the network rehabilitation is substantial and mostly concessional. Transnet has assembled a €350 million framework loan from the European Investment Bank for rail and port infrastructure renewal, accompanied by a €21 million European Union grant. Material presented at African Mining Week also identifies €300 million from Agence Française de Développement, $278 million from the New Development Bank and $1 billion from the African Development Bank, alongside a R94.8 billion South African government guarantee package.

That capital is going into track, signalling, power systems, yards and port connections, which is the correct place for it. It also tells you something about timing. Money committed to rehabilitation in 2026 shows up as reliability in 2028, not in your next quarter.

What a shipper should do between now and March

Four pieces of work fit inside this financial year, and none of them requires a rail contract to exist yet.

Know your rail-able tonnage. Most manufacturers and distributors have never measured this properly. The question is narrow: which of your lanes have origin and destination points within economic drayage distance of an operating siding, at volumes above roughly 1 000 tonnes a month, on commodities that tolerate transit variability. In most SA businesses the honest answer is a smaller share of the freight bill than the board assumes.

Check siding access before you check rates. A slot allocation on a corridor is not access to a siding at your plant. Sidings are separately owned, separately maintained and in many cases separately disused. Establishing what condition yours is in, and who is responsible for it, takes months and cannot be started after a rate is agreed.

Model road-equivalent cost properly. Rail comparisons usually get built against a road rate per tonne. The real comparison includes drayage at both ends, longer transit, larger consignment sizes, and the working capital tied up in inventory that is now on a train instead of in a warehouse. A lane can be cheaper per tonne on rail and more expensive per year in total.

Do not cut road capacity early. Contracted road capacity on the Johannesburg to Durban and Johannesburg to Cape Town corridors is competitive because volume is high and trucks compete for it. An operator that cuts committed road volumes in anticipation of 2027 slots, then finds the slots start late, buys spot capacity at peak in a market that has repriced.

The realistic read

The reform is real, the institutional parts exist and the money is committed. The programme has also moved before, and the current expectation of April 2027 depends on safety approvals, rolling stock availability, commercial agreements, siding condition and port connections all arriving together.

Plan on the assumption that some corridors work well from 2027/28 and others take another year. Build the qualification work into this financial year, when it costs analyst time rather than freight spend.

Performance in this reform will be measured in tonnes, not in agreements signed. Until the tonnes move, road is still your network.

OptiChain Solutions works with South African manufacturers and distributors on network design, freight cost modelling and DC operations. If you want your rail-able tonnage quantified before the February budget round, that is a two to three week piece of work.

Re-test your DC network before the trains run

If rail changes your inbound mix, your slotting and pick faces should change with it. We can model the effect on the WMS you already run.
