Train fact: the longest* train ever

like all things to do with railways, you can get pretty granular and pedantic with this one, so this is likely to also be the longest post ever. Sorry, but actual facts (and pretty pictures) under the cut!

The longest passenger train in regular service is Australia's 'Ghan, a luxury tourist train that runs between Adelaide and Darwin, and averages 774 m/2,539ft in length. that's twice as long as the Empire State building is tall.

The reason I say "in regular service" is because the longest passenger train EVER was run by the Rhaetian Railway in Switzerland, to celebrate 175 years of Swiss railways, and that was more than twice that long at 1,910m/6266.4ft. Almost an entire Kentucky Derby worth of train! It had to go incredibly slowly, maxing out at 35km/h, to avoid overloading the electric systems of the railway and local power grids.

[Video desc: a youtube video from CBS news of the recordbreaking passenger train. The train is made up of several red electric trains coupled together, and moves through alpine landscapes of mountainds and coniferous forest. It is so long that it is visible only in coils, like a snake. Some shots show the train leaving one tunnel while entering another, or driving under a viaduct while the tail end crosses it, and several shots show people watching and taking photographs.]

But, the thing with passenger trains is that they have a lot of rules and regulations applied to them that freight doesn't have to follow. So freight trains get HYUGE.

The average American freight train (I consider the USA to be freight trains' natural habitat because there is a whole bunch of wide open space for for them to crawl around) is 5400 feet long, and the standard in Europe is around 3000ft. That's a 10-20 minute walk at average adult walking speed, just to go from end to end. You know when you stop at a level crossing, and a train goes by, and it seems like it's going by forever? That was probably one of these.

But the average frieght train is peanuts to mining trains. Trains came from the mines, and they still dominate there. The biggest trains in the world are consists of ore and coal, run by tiny crews from extraction point to export. This has always been true.

For example, the Datong–Qinhuangdao railway in China runs coal trains daily that are 2.614 km/8576 ft long. That's more than 1.5 miles, or three times as long as the burj khalifa is tall. And that's the standard for that line.

But that doesn't break any records.

The longest production train, running regularly, is the Sishen–Saldanha railway line's maganese/iron ore train. These trains are four kilometers long. 4,000 meters, almost half the height of the highest peak on earth, in wagons full of metals. Too long to be seen in a single photograph- the one below was stitched together from four separate pictures, taken from the air:

and that's still not the record!

The record for longest frieght train is held by BHP, an Australian mining company. It was made for the record, but the capacity is still there. This train ran on june 21st 2011, and was 682 wagons long, over seven kilometers. Almost twice the length of the Sishen–Saldanha's, and a quarter the height of Olympus mons. If you stood this train on its end, it would be taller than Mt Denali. If you started at the front of the lead locomotive, and ran as fast as you physically could, you wouldn't reach the last wagon for an hour.

There are entire branch lines shorter than this train.

Unfortunately, there are no good photos, because nobody in space had time for railfanning that day, but there are plenty of pictures of other BHP trains!
