One of the main goals of this is to not have the russian gauge available in case russians attack, so that logistics deeper into Finland cant happen easily with the same train, so backwards compatability is not desired.

It's not like this results in a categorical difference in difficulty. Gauge switching infrastructure is common at borders. Yeah stopping and switching is slower than driving right through but it's not the end of the world in the long tail of military logistics.

Russian military logistics _heavily_ depend on trains, everything that can go on a train, does so. Flight and vehicle stuff is mostly an afterthought.

Any hindrance we can put on the Finnish-Russian border to stop them just unloading 12 cars of fresh troops in the middle of the country is a good thing.

Gauge switching requires trains outfitted with specialized axles (increasing the cost to invade), requires trains to stop (increasing the train's vulnerability to attack), and requires switching stations which themselves are juicy targets and can't be repaired nearly as trivially as an ordinary length of rail.

It adds time for each train though.

And if you're Russia wanting to invade Europe, it's better to do the Gauge switching right near your own border rather than on the far side of Finland. So while this may make it harder to invade Finland, it makes it easier to invade Europe as a whole.

But if the Spanish can muster dual gauge trains, what's to prevent the Russians from doing the same? Or is the Finnish gauge a state secret?

It's less about what the Russians can do and more about how fast European and NATO countries can move assets to a potential invasion front line; as it stands, they're slowed down at the borders needing to switch to the different gauges.

> what's to prevent

Conceptually? Nothing.

But building such trains, at scale, takes a load of resources. Resources which could otherwise be used to build tanks, guns, missiles, and similar high-priority products.

The difference between Finnish and Russian gauge is 4mm

IIRC the diff to European standard is closer to 10cm, still doable but a hurdle compared to just driving a trainload of troops to the middle of Helsinki it's a bit harder

This doesn't seem like it can be a goal given

> maybe in 2032 we can start construction

I mean unless the plan is to assume Russia won't attack until e.g. 2040 when construction will be complete && Russia can't implement multi-gauge trains that Spain is already using now?

Even if Russia's conquest of Ukraine were to end tomorrow, they would take a few years to recover before mounting their next offensive. And Finland isn't first in line on their list of next invasion targets, that would be either Georgia, Moldova, or the Baltics.

And in any case, just as in computer security, a security posture does not need to be unassailable, it just needs to be expensive enough to deter the enemy. NATO countries (well, the ones that haven't already been compromised by Russia) will be happy to fund the gauge switch, as would the EU in general for the sake of greater economic integration. Meanwhile, it increases the costs on Russia and slows their advance. It's a win no matter what.

Like most such things, it's probably mostly symbolic, so politicians can say they're doing something in defiance of Russia (which is a very popular thing to do in Finland right now, or most of the west for that matter). I guess they'll back down on it when by 2032, everyone realizes it doesn't matter since wars will be fought with small autonomous drones and any railroad would be sabotaged in an instant.

Wouldn’t it be simpler to make a “train moat” by disconnecting rails from Russia? Or would they run the trains on dirt for a mile and re attach?

Building temporary bridges in wartime is pretty normal.
