>Your argument is the same as Iraq being a realistic threat against the US. Your argument appears to be that your enemy's fear driven by losing 27 million people during an invasion/war of extermination is exactly equivalent to your country's fear of weapons that were imagined solely for the purposes of justifying an invasion. My argument was that it is quite easy to get a domestic population to treat all of the enemy…

Which 27 million deaths? Finland never had 27 million inhabitants.

The Soviet Union lost 27 million people in WW2. It was a minor detail you swept under the carpet in your comment.

No. The closest living analog to the Nazis today is our allies in Israel and like the Nazis they arent shy about endless expansionism for the sake of creating lebensraum for their ubermensch. Theyre not very shy about the holocaust theyre committing either. Russia never went on an extermination drive in order to create an ethnically pure ethnostate. The biggest western geopolitical mistake of the 2020s is assuming th…

> Russia never went on an extermination drive in order to create an ethnically pure ethnostate. Technically correct is the best kind of correct.

Technically I'd prefer to be living in a newbuild in Mariupol paying taxes to a different government rather than having the Israeli army drop bombs on my head and starving my entire family until we are all dead.

Small distinction to you perhaps, but to me it's a bit more than just "technical".

I made a more nuanced and historically grounded point, whereas your post was a sarcastic oversimplification. So no — you didn't say what I said. I emphasized the diversity and complexity of postbellum labor in the South; you gave a glib summary that oversimplifies it as mostly “recently freed black slaves paid almost nothing + ‘free’ prison labor.”

Your point is flat out misrepresenting the situation. Especially by listing White workers first. At that time, the only white workers in the south who would have been moving rail and driving spikes would have been on a prison work detail or in a similar severely legally compromised situation. Even getting white workers to couple cars didn’t happen until much later.

Again, you didn’t say what I said. I described a complex labor force with various roles and racial backgrounds. You gave a sarcastic oversimplification, and now you’re shifting to a narrower historical claim that contradicts your own original tone.

“Even getting white workers to couple cars didn’t happen until much later”

That’s an overstatement. While Black workers were indeed disproportionately given dangerous roles like coupling cars in the South, it wasn’t unheard of for white laborers - especially poor or immigrant - to do that work too

The labor structure wasn’t as racially absolute as you’re implying

There are no ready-made gauge changing machines, though. Not exactly a big market for those.

Once Spain and Portugal move from Iberian gauge that market will increase a lot. Which is kinda inevitable with the added environmental pressure on flights.

It is taking decades to achieve though!

Makes it even crazier that Bart would choose a non-standard gauge 75 years later. And now they're stuck paying for custom trains with less flexibility and longer lead times.

BART was always going to need custom trains for other reasons beyond track gauge. Electric third rail at those speeds isn't standard. 125kV pantagraph would mean big expensive tunnels and stations due to clearance requirements.

12.5kV?

In Spain it's ongoing, very slowly, since the first international gauge high-speed rail line started operation in 1992. It's a slow and quite annoying process. For example, to reach my region, trains from Madrid have to change gauge because my region still has the old one. Apart from spending around 10 minutes doing this, this has caused a lot of problems because it essentially means there is a single model of 300 km…

You lost me at ‘single model of 300km/h train that can make it here’ Meanwhile here in Australia our “fast rail” trains go 160km/h. Unless it’s over 32 degrees, then they slow down. And if it hits 36 degrees they slow down even more (90km/h) And it gets that hot here a lot… https://en.wikipedia.org/wiki/V/Line_VLocity https://www.vline.com.au/heat

There ought to be good reason for optimism with this project. The land is already purchased so you “just” need to re-lay the track. Ballast cleaners* are a thing and they are already pretty amazing at what they do, namely taking apart track and then putting it back, in place, from a machine that runs on those very tracks itself. I could imagine a giant version that not only cleans the ballast but also unties then ret…

A ballast cleaner wouldn't be enough, because you basically need to swap out the sleepers, too, so you need a complete track-relaying train. And anything involving switches and crossings needs to be done conventionally, because those cannot be rebuilt by simply switching out the sleepers for standard gauge ones.

One such relaying train does 500m in one hour, including new sleepers. Seeing several such things in operation several times in several places, this should be doable without much modification when the gauge change is so small. Regarding switches and crossings, those come preassambled nowadays, and are just 'plugged in'.

If you want to nitpick about some corner case, go ahead. I have this feeling that Finland's railway tracks are not set in concrete at street level ;)

But they are set into prefabricated concrete sleepers, which cannot be modified to a new track gauge and instead need to be swapped out completely. Whereas during the US gauge change, the railways used wooden sleepers, with the rails fastened simply with nails hammered into the sleepers, so it was simply a matter of pulling out the nails and hammering them in again at the new track gauge.

There are metal sleepers that sit on a concrete pad. The challenging part is the rail is encased in concrete that enables drivers to drive over the tracks.

Getting to the sleepers would take weeks of jackhammering plus more time to repour the concrete.

anti-invasion projects. Up next posting pro Russian narratives or other anti democratic ideologies gets you deported to the real existing implementation of said ideology. The free speach "autocracies pushing internal subversion" has to go. Yes, this cuts left, right and center.
