The 7.6 km Train That Claims a 25-Year-Old World Record

It is longer than 70 football pitches laid end to end. It took two days to travel 861 kilometres, and when its front reached its destination, its tail was still 7.6 kilometres behind. South Africa says it has just run the longest freight train the world has ever seen — and taken back a record Australia has held for 25 years.

There is one catch. Guinness World Records has not certified it yet. So is this a genuine world record, or just a very long train with a very bold claim? The numbers, and the history behind them, make the answer more interesting than either version.

What actually ran

On 17 October 2026, Transnet Freight Rail sent an empty train of 696 ore wagons out of Saldanha Bay on South Africa's west coast, bound for the iron ore mines at Sishen in the Northern Cape. It reached Loop 18 the next day, 18 October, having covered the full 861-kilometre Iron Ore Export Line.

The formation measured 7,602 metres — 7.6 kilometres, or 4.7 miles — and weighed 15,830 tonnes. Thirteen locomotives were spaced along its length, a mix of Class 15E electrics and Class 43D diesel-electrics, all synchronised by a system called Radio Distributed Power. That technology is the quiet hero of the story: it lets locomotives spread through a train coordinate their acceleration and braking as one unit, so a 7.6-kilometre string of wagons does not tear itself apart when it starts, stops, or climbs.

Every one of the 696 wagons was empty. This was not a commercial delivery. It was a test — run immediately after the line's scheduled maintenance shutdown from 6 to 16 October — to find out whether the corridor could safely handle a train of this length.

The 25-year-old record it is chasing

To understand why 7.6 kilometres matters, you have to go back to June 2001. That is when Australian mining giant BHP Iron Ore ran a 682-wagon train, 7.353 kilometres long, from its Newman and Yandi mines to Port Hedland in Western Australia. Guinness lists that run as the longest freight train ever operated — and it was also loaded, carrying 99,732.1 metric tons of iron ore.

Transnet's train beats it on length by about 250 metres and on wagon count by 14. But it was empty, and it was a test run. That distinction is why the record is still described as "claimed" rather than confirmed: Guinness has not yet certified the October run, and independent verification was still pending when the story broke on 20–21 October.

There is also a neat piece of history here. South Africa held this record first. In 1989, Transnet ran a record-breaking train on this very same Sishen–Saldanha line. Australia took the title in 2001. Twenty-five years later, the title may be coming home — on the same track where it started.

Why run a train this long at all?

A 7.6-kilometre train is not a stunt for its own sake. The Sishen–Saldanha line is South Africa's main artery for iron ore exports, moving ore from the Northern Cape to ships at Saldanha Bay. Longer trains mean more ore per journey, fewer trips, and lower cost per tonne — if the railway can handle them safely.

That "if" is doing real work. A train this long faces problems ordinary trains never meet: braking forces that ripple down the formation, couplers under enormous strain, and the simple fact that the front of the train can be in a different landscape — and a different gradient — from the back. Radio Distributed Power, with locomotives distributed through the train rather than bunched at the front, is what makes it possible at all.

Transnet's chief executive, Russell Baatjies, said the operation would help engineers improve the country's ability to move minerals over long distances. But the operator has not said whether trains of this length will enter regular service, or what they would add to the corridor's annual capacity. For now, it is a demonstration — a proof that the railway can do it, not a promise that it will do it every day.

So, is it the longest train in the world?

On the numbers, yes: 7.6 kilometres is longer than any freight train previously run, and the previous holder itself held the title for a quarter of a century. On the paperwork, not yet: until Guinness certifies the run, the record remains a claim, not a certificate.

That is the honest way to read it. South Africa has built and run the longest train ever assembled, on the same line where it set the record 37 years ago. Whether the record books catch up is now a matter of verification, not of length. And the next question is the bigger one: if a railway can run a 7.6-kilometre train once, how soon before it runs one every week?
