On top of that, the finnish embassy basically says "Yes, we can issue you a finnish visa, but you should not count on being admitted to Finland with that visa", and that is on top of having a valid PCR test. That's why I hold my expectations really low about international train travel. With airplanes it's actually much simpler, since air travel acts as a network and routes around failures (such as, even if you can't get from country A to country B directly, you can usually go transitting via country C without any restrictions).
