Not sure if it directly helps here, but multi gaage railway cars are a thing. Iirc on some European lines, the trains switch their gauge.

[dheera]

Yeah some overnight trains can adjust their gauge on the France/Spain border.

On the China/Mongolia border on the other hand they disassemble the train, lift the train cars up one by one (with passengers inside), switch out the boogies and then reassemble. 3 hour process, you can fully sleep through it and not notice.

Not notice loud banging and violent shaking underneath you? You can sleep through that, with practice, but you will notice it.

[dheera]

It's actually rather quiet from the relatively sound-proof interior, and there is no noticeable shaking.

These aren't American trains.

If it’s taking 3 hours on a passenger train, a 5-10 minute transfer seems vastly more efficient.

[taschmex]

Yes, but most people can't sleep through a train transfer

[gpvos]

On a night train such as the Transsib that takes several days to get from A to B anyway, being able to sleep through it and not needing to lug your stuff around is usually considered more important.

(Although in some cases you are woken up for border formalities.)

> (Although in some cases you are woken up for border formalities.)

Yeah although you can just stay in bed for this. I've been on the train. The Chinese officials just wake you up, stamp your passport, and off you go to sleep.

Then the Mongolian officials came on, asked me a couple questions to see whether I respected their country, why I was going there, grumbled something unintelligble, stamped my passport and moved on.

Much better than getting in line for 2 hours if you ask me (which is what happened at the Bulgaria/Turkey border and the Georgia/Armenia border when I crossed those)

For day trains as well, more often within Spain than on the border with France.
