🚨 Snow plow tram klaxon 🚨
In any sane world we would call this a Tramboni. (It's possible this joke only works in hockey-playing countries en.wikipedia.org/wiki/Ice_res...)

This may well come as a shock to many Stockholmers but the scale and coverage of our transit system compares well to some of the world’s most dense. It’s less of a surprise to those of us who have worked hard to make it happen!

What urban areas in the world have the longest existing/under construction metro networks per capita?
In a quick analysis using Transit Explorer & EU GHS-UCDB 2024 data, the top urban areas are:
1—Chengdu
2—Hangzhou
3—Ningbo
4—Xuzhou
5—Stockholm
6—Zhengzhou
7—Singapore
8—Xi'an
9—Hamburg

I am also reminded by these graphs that the Norwegian word for a non-electric car is "fossil car". Perhaps we should all adopt that term, now that the short form acronym for Internal Combustion Engine is so strongly associated with something far more sinister.
As a Stockholmer this is not easy to admit but visiting Oslo feels - at least from a transport perspective - a bit like visiting the future:
- car traffic is barely increasing despite population growth
- transit, walking & cycling is handling all of the growth
- 95% of new cars are electric

It is noticeably quieter and there is no diesel smell that otherwise tends to hang around in the cold air.
Someone said they thought the snow stayed whiter because of the EVs. I am skeptical, I would imagine that's more to do with tyre wear - but less traffic in the centre almost certainly helps

Great graphic from the folks at @cleanenergycanada.org that shows Canada falling dangerously behind in the global race on EVs.
Just saying: 2026 would be a great year for the feds to get serious about climate change again.

When a cycling city has a walkability problem, there’s probably too much curb parking for cars.

EV sales in Sweden were tracking those in Denmark and Norway - until the government weakened purchase subsidies and reduced the cost of ICE fuels. Policy makes a difference.
Andelen elbilar av nybilsförsäljningen rusar i både 🇳🇴 och 🇩🇰. 96% i 🇳🇴 och 69% 🇩🇰. Även 🇸🇪 gick samma väg fram till 2023 då ökningen avstannade tvärt runt 35%. Politik spelar roll

…and a happy 20th birthday to congestion pricing in Stockholm. We can assure our younger sibling that the benefits will keep piling up and that people will quickly wonder why we ever thought it was fair to being your car into the congested downtown for free

Just watched the new Knives Out and I think it's really important you know that the scene in the Seminary's Gym is filmed in the same place Rick Astley filmed the music video for Never Gonna Give You Up.
I saw the window tracery and immediately made my friends pause the film so I could tell them.

It’s one of my favourite stories so I read, listen to, or watch a version A Christmas Carol every year
It’s not an original observation that there are more people than ever who needed a visit from some ghosts last night
I reflect on what my ghosts would show me - it’s never too late for salvation

Every place that’s implemented congestion pricing started the discussion with ”but that could never work here”. And then it does.
Year 1 data on congestion pricing in Manhattan…
* Vehicle traffic: -11%
* Foot traffic: +3.4%
* Storefront vacancy: -0.9%
* Pollution: -22%
* Revenue for mass transit: $548M
So YES this has been a huge success.
