It took quite a while, but the paper about the history of high-speed rail planning in Italy that I co-authored with
@beriapaolo.bsky.social
is finally out! It's open source, so you can read it at length (it is pretty long), But here is a TL;DR: 🧵

Another railway station opened in Naples today, Monte Sant'Angelo. As always over there, stunning architecture but abysmal construction times (works started in 2008) and mediocre service (line 7 will operate as a 1-station shuttle initially).

If you are in Rome in the next two months, there is an exhibition at Palazzo Venezia about the history of Italian railways since Unification, on the occasion of the 120th anniversary of the creation of the Italian Ferrovie dello Stato in 1905.

I was going through some old pics and I found one that really conveys why the Brenner basis tunnel was necessary. This picture was taken in Sterling/Vipiteno, pointing north toward the Brenner. Here starts the 2.3% ramp that brings the line from 950m to 1,374m at the Brenner in 22km

Today, after 20 years of stop&Go works in very southern Italy fashion, the Baia new station on the Cumana line near Naples has been inaugurated. As always, fantastic architecture, but poor execution and mediocre service, unfortunately.

If only there was a technology that allowed the contemporary flow of trains and cars crossing each other. Something that would make them go at different levels, for example. I'm sure there is some Silicon Valley start-up that is looking into this problem right now and will save us.

I've done something that I don't do very often. I wrote a short, quick polemic post. It was prompted by a discussion in here. It's about why I'm still skeptical about ALTO's HSR project and why there is no way around transparency in public projects.

We have zero hints right now about alignments, service levels, station locations, urban integration, etc But they want it to break ground in four years. Good luck, folks. Especially when the generic "I love the idea of HSR" crowd will turn into a "don't want that massive infra in my backyard" crowd

Canadian suburban planning can be really weird. Just the most vanilla staple sprawl complete with the fake urbanist strip mall cosplaying as a main street (Marketplace Ave 🫣)... but with a random transitway across it. And this is Barrhaven, a far flung leapfrog suburb outside of Ottawa's greenbelt.

Folks, what terms would you use to translate the French "hypercentre," which is used in planning jargon, to refer to the very core of the city center? Would "inner city core" or "inner core of the city center" work?

From an Egis presentation at CUTA yesterday about integrating bike infras and trams. The French do multi-phase pedestrian crossing, and that's why they can have absolute priority and we can't. Also: their TSP philosophy is fundamentally different >>> Paging

Almost unrelated comment, but it's interesting how successful Renaissance has been at "public relations", especially for non-italians, while the actual urban and economic renaissance of Italy (and most of Europe) really happened two centuries earlier, in the 13th century rather than the 15th.

Nothing of this would have been possible without the people I have been reading online for more than a decade (I keep a list of references you can look at:

). This is mostly a reframing about 15 years of housing discourse in a convincing and coherent way. I hope.

When I was hired at
@vivreenville.bsky.social
in 2020, I had about a decade of exposition to anglosphere discourse on housing and found that in Québec professional circles, almost no one else did. We had failed to learn from the failures of English Canada and the US, and it was already too late.

I cobbled together four photos of the same corner of via Rizzoli in Bologna, taken between the 1930s and the early 1970s. They show the evolution of road use and design in the early days of mass automobility. A pattern similar throughout the so-called developed world. 🧵

BTW, for this line RFI "invented" a new civil engineering beast that they called "gallerodotto", that is a tunnel-(via)duct, which is essentially a very low-rise viaduct with minimal spans that works as a "permeable embankment" in flood-prone lowlands.

I think we underestimate how appreciated the existence of non-car alternatives is for the layperson. The mayor of Deux-Montagnes says that he loves the REM, and recognizes that mobility has changed, that car- & bike-sharing are picking up even in his far-flung suburb.

Train cosplaying as a plane (Seriously though, I have nothing against providing safety info to travellers, but it's just that they are so inconsistent across train operators that they feel pretty random, unlike for flights were there is string consistency in safety provisions worldwide)

It's challenging to evaluate the long-term effects of broad mobility policies due to the lack of consistent time series and the difficulty in controlling for external factors. But keeping bus speed stable or even slightly increasing it in the face of rising automobility can be called a success.

It's fascinating how traffic control practices tend to evolve in different ways between countries and are so hard to change later Like the French making two-phase signals a quasi religion to the point that it's hard to find directional traffic lights in Paris.

Take these numbers with a grain of salt, but that's how transit ridership in Bologna look like 1932-2024. If we exclude the 1975-85 period (I explain why in the next post), ridership per capita has been above the late 1960s lows until now, and reached an all time high in 2019
