> will cost billions of euros, affect more than 9,200 km of track, and take decades

How is a change like this going to be implemented? E.g. are they going to mainly update some tracks everywhere (and have two systems running in parallel), or all tracks in selected areas (and have passengers change), or something else?

Was there a comparable large scale rail infrastructure change in some other country?

I think you can ”upgrade” the tracks to use three rails so you can handle both track widths. Also there are trains with adjustabe axle widths.

Part of the motivation is removing the Russian gauge rails such that they can't be used in the case of invasion, so I don't think dual-gauge is really an option here.
