Sure, logistics matter. I'm sure Russian-gauge railroads in Finland would be mildly convenient for invading Sweden, provided you can first invade and utterly defeat Finland quickly enough that the railways survive.

But if Putin could do that (he can't), railway gauges would be the least of our worries.

So the drone bit was a non sequitur.

As to railways surviving it’s relatively difficult to effectively destroy rail infrastructure. Making the call to cripple your internal infrastructure is tough especially in such a dire situation, it’s also a really large target. Taking out some strategic bridges is easier but most local issues can be quickly fixed when you talking million men armies.
