If you're a regular reader of this blog, you'll know that I like trains. So when I come across a video titled "This Sahara Railway Is One of the Most Extreme in the World," there's a high probably that I'm going to watch it — even if it's over 6 years old. Now for a second, I thought that I may have already written about this rail line, but AI tells me that I haven't.
The Mauritania Railway is one of the most iconic and famous lines in the world. It's approximately 704 kilometers long and it was built for the sole purpose of transporting iron ore from the Zouérat mines in northern Mauritania to the port city of Nouadhibou on the Atlantic coast. Iron ore represents somewhere around half of Mauritania's exports.
This railway runs some of the longest trains in the world — each train can have over 200 cars, which translates into trains that are up to 3 kilometers long. They can also transport up to 17,000 tons of iron ore, making it one of the heaviest trains anywhere in the world.
But what I find most fascinating about this railway is the informal economy that unintentionally emerged on top of it. Because the trains return from Nouadhibou to Zouérat empty, local fishermen and traders use it to transport product inland to towns along the line. And for many of these towns, this is their lifeline — it's their only connection to the outside world.
It's not a fun trip, nor is it a safe trip. It also takes 20 hours to travel from one end to the other. But it's importantly free and it provides economic opportunity. It's an extreme example of the power of rail. Here you have a single railway that likely shoulders at least a quarter of the country's entire GDP, and that's without including any of the benefits derived from its informal contributions.
If you haven't yet seen the above video, I would encourage you to take the 12 minutes and give it a watch. The visuals are important to see. And there's a reason it has over 10 million views.

Here is a neat tool (created by Benjamin Td) that allows you to quickly see how far you can travel in Europe by rail in 5 hours. The way it works is that you just hover over a train station and then the relevant isochrone will show up. Above is what that looks like for Paris' Gare de Lyon, which has one of if not the largest catchment areas from what I can tell after playing around with the tool for a few minutes. The data being used to power this map is from Deutsche Bahn. And if there's a transfer on any of the routes, the tool assumes you can make that happen within 20 minutes, which may or may not be realistic. Regardless, it's fascinating to see just how connected (or disconnected) some cities are. It's also a shameful reminder that a
Well here are some interesting figures (via MIT Technology Review):
In the past two decades, about 400 million people moved into China's cities -- so more than the entire population of the United States

Well here are some interesting figures (via MIT Technology Review):
In the past two decades, about 400 million people moved into China's cities -- so more than the entire population of the United States
By 2035, about 70% of China's entire population is expected to be urban (up from 60% today and up from 30% two decades ago)
To accommodate this scale of growth, China's national urban development approach has shifted to something that now revolves around city clusters, or megalopolises (term coined by French geographer Jean Gottmann back in the 1950s to describe the Boston-Washington corridor in the Northeastern US)
By 2035, there are expected to be five major city clusters (see above)
One of the reasons for this is to improve cooperation across the various clusters -- less competition and less redundancy
But it's also about creating smaller more manageable cities -- is this what one needs to do after a certain scale, go polycentric?
To service these clusters, China is rolling out a network of 16 new high-speed rail lines
By 2035, China expects to have 200,000 kilometers of rail, with a third of it being high-speed -- assuming this happens, China will be home to 60% of the world's high-speed rail coverage
Current cost estimates for the construction of this network comes out to about US$150 million per kilometer
1-2-3 Rule: The plan is that everyone should be able to get around a city within 1 hour; a city cluster within 2 hours; and travel between the country's clusters inside of 3 hours
China is building.
