Paris has a massive transit project that is currently under construction called the Grand Paris Express. It consists of 4 new metro lines, 1 line extension (at both ends), 68 new stations, and 200 km of new tracks. The first phase was the extension of Line 14. That opened last year. And the new lines are planned to open in stages up until 2031. I have no idea if they're on schedule and/or on budget, but here's a map of the GPE project:

Here's what it looks like if you overlay all existing metro lines (note how concentrated they are in Paris proper and how they're clearly designed to bring people into the core):
Here's what it looks like if you overlay all existing tram lines:
And finally, here's what it looks like if you overlay all existing RER lines (suburban rail):
At this point, the map is getting visually pretty cluttered. But if you look at how the GPE lines compare to what's existing, I think you'll start to see just how important this project is for the Métropole du Grand Paris (or Greater Paris). It creates a new set of concentric rings in the inner suburbs and, for the first time, it will allow Parisians to travel around the region (via rail) without first passing through the core of the city. So it's in effect both an expansion and a stitching together of the city.
But let's put some numbers to this.
According to a recent memo by Apur, which looked at the economic composition of the station areas, about 21% of all salaried employees in Grand Paris are located next to one of the new 68 stations. As a total number, this works out to about 934,000 employees (2022 figure). And included in this figure is La Défense, which is the office district where Paris decided to put most of its tall buildings. This has the highest concentration of jobs at approximately 163,599 salaried employees (again, 2022 figure).
Another way to think about these station areas is that they represent what many are now calling New Paris. This is a part of Paris that is less encumbered with history and, therefore, more open to change and new ideas. This creates an exciting opportunity, and already we're seeing that take hold. Later this week on the blog, I'll talk about a specific project in Greater Paris that is currently under construction and that I was fortunate enough to tour on this trip.
The other day I was speaking to a Korean friend of mine and he was telling me about Seoul's new GTX-A commuter railway line. This line opened at the end of 2024 and is part of a broader Great Train eXpress initiative that includes 3 lines (A, B, and C) and that is intended to establish a new "30-minute commute zone" surrounding Seoul. A is the first line to open. C is scheduled for completion in 2030. And already, three more lines are now being planned: D, E, and F.
What this first line has accomplished is pretty extraordinary. GTX-A connects Paju in the north to Seoul in the south. Paju sits at the northern border of South Korea (and therefore houses many US and South Korean Army bases) and has a population of over half a million people. Prior to GTX-A opening, this commute used to take approximately 90 minutes by conventional subway and up to 90 minutes by car, depending on traffic.
Today it takes exactly 22 minutes! If you're interested in seeing a complete walking video of this commute, click here.
The GTX system is a higher-speed railway line. Meaning, the trains are designed to operate up to a maximum speed of 180 km/h. Average speeds vary depending on the segment and stop spacing, but it seems to operate at an average speed of
We arrived in Tokyo late last night. Our departure was delayed by a few hours, but we ended up sleeping most of the flight, and so we landed relatively refreshed and ready to tackle all of the late-night snacks at the closest 7-11.
The onboarding process for taking the train into the city was as easy as it could have been. I was able to add and then load their Suica card directly from Apple Wallet. (Thanks for the tips, everyone.)
Here's us, taking up too much room on the train with our two ski/snowboard bags.

What this also means is that, as new GTX lines continue to come online, the geography of the Seoul urban region will continue to get redrawn. Suburban regions that were previously far out, are now going to get "pulled in" and function as more integral parts of a contiguous city. This improved access should also alleviate housing pressures by effectively opening up more supply.
I mean, 22 minutes is nothing. It can take longer than this to travel 3 blocks on a Toronto streetcar during rush hour. GTX is a prime example of the magic of rail and what's possible once you accept that highways (and tunnels underneath them) aren't going to be what efficiently move the most number of people around a big global city.

However, I will say that Shinjuku station -- which is the busiest train station in the world, by far -- is just as confusing as I remember it. Between the vastness of the station and overall network, and the language barrier, it can be a real challenge to figure out where to go to make your connection.
But ultimately, we made it to our hotel, and to 7-11. In case you're wondering, and to give you an idea of scale, my legs absolutely hang off the end of these beds.
I have no idea what the circular thing was in this bowl, but it was good, hot water was readily available in the store for these purposes, and I was able to supercharge the entire thing with some charcoal-grilled chicken from a separate package.
The first time I visited Japan, I had a cell phone with one of the first ever color screens. I thought this was a huge deal. And, I had a standalone digital camera that was about the size of a small wallet. I also thought this was a huge deal. Sadly, I'm not sure where most of these photos are today (though I still have the phone).
So it's exciting to me that I'm now writing posts and sharing photos with all of you on a decentralized and open ledger that is intended to act as permanent information storage. In theory at least, these posts and these photos will be around forever, even if Paragraph as a company goes away.
Which means I'll be able to look back on the above photo and remind myself that I took it from the window above my hotel bed when I woke up at 530AM, I couldn't sleep, and I decided to just get up and write today's post. Tokyo is such an awesome city. It's great to be back after all these years.
