Between 2010 and 2025, the Métropole du Grand Paris added nearly 160 kilometres of new or extended transit lines and opened 200 new transit stations across the region. These numbers include all modes of transport, including RER, metro, tram, cable cars, and BRT. On top of this, a further 199 new stations are scheduled to open between 2026 and 2032 (a shorter time period), meaning there's an argument to be made that Paris is getting better and faster at delivering transit.
Imagine that.

This, as we have talked about before, is a remarkable achievement and one that is reshaping the Métropole — particularly outside of Paris proper. Take a look. Here's a recent study and map from Apur that shows how these completed and upcoming lines have impacted, and are expected to impact, transit access in the region:

The coloured areas represent access to transit within a 15-minute walk (assuming you're able to walk at a reasonable 4 km/hr). The lightest blue areas are lines/catchment areas that existed in 2010. The medium blue represents lines/areas that came online between 2010 and 2025. And the darkest blue represents lines/areas that are scheduled to come online between 2026 and 2032.
If you're familiar with Paris, you'll be able to tell that the majority of the recent transit expansion has happened outside of the boundaries of Paris. This is important because prior to 2010, all of Paris was already well-served by transit (seriously, 100% of the population was/is within walking distance of at least one transit line).
However, this is not the case in the rest of the Métropole. In 2010, about 56% of the population (outside of Paris proper) had access to at least one line, with 23% having access to two. As of 2025, this number has increased to 66%. And by 2032, with the opening of the lines currently underway, it is expected that 80% of the population within the entire Métropole will be transit-connected.

It's hard to overstate the importance of these changes. The Paris region has long been criticized for the divide that exists between its historic centre and its surrounding suburbs and cities. Historically, this has been a socio-economic divide, and a built form divide. But this divide is now being erased. New infrastructure is stitching the region together, tightening its geography, and encouraging the development of new economic centres.
Forget the Paris you know. The growth and change are now happening along its edges. Welcome to the new Greater Paris Metropolis.
P.S. To commemorate the 10th anniversary of the Métropole du Grand Paris (created on January 1, 2016), Apur recently published a book called Atlas de la Métropole du Grand Paris. I haven't been able to find a site that will ship to Toronto, but if you're in Paris, you can order or pick one up at the following bookstores.

There is a school of thought that elevated rail is bad, or at least suboptimal, for cities. The thinking is that it's a visual blight, it's noisy, it disconnects neighbourhoods, and it can even reduce surrounding real estate values. Having a train passing directly in front of your window is admittedly less ideal than not having a train passing directly in front of your window.
But there is no shortage of examples from around the world where elevated rail does far more to benefit a community than detract from it. Tokyo is perhaps the obvious place to look. It is decidedly rail-oriented city with the majority of its network above ground and countless examples of active commercial spaces being tucked under and adjacent to elevated rail.
Here, for example, is a restaurant that I visited on my last trip and that was immediately adjacent to a track:



But you don't have to travel all the way to Japan to find examples where elevated rail does little to detract from the urban experience. Here's Marine Drive station in Vancouver, integrated into a newish development:

And here's what the elevated guideway looks like as it heads toward the station:

The obvious advantage of elevated rail is that it's significantly cheaper than underground rail. According to global data collected by the Transit Costs Project at New York University, underground rail tends to be at least 2x the cost — often it's even more. Are the benefits worth this additional cost, and is it worth building less overall transit with the same capital budget?
Elevated rail is not without its drawbacks, but good design and urban sensibilities can help to mitigate many of them. As is the case with a lot of urban design, what matters most is how we treat the ground plane underneath the rail. So, to the extent that it remains out there, I think it's time we get rid of any stigmas associated with elevated rail. More transit is better than less transit.

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.
