Probably more being prepared for Rail Baltica. Building a tunnel from Talinn to Helsinki has been talked about for some time, which would create an actually busy rail connection to another country with standard gauge. Currently there is only one, which is with Sweden along the Baltic coast. That however is so far north, that few people use it, so it does not matter.
Gauge can be changed rather quickly, if need be. That happend in WW2 between Germany and the Soviets depending on where the front was.
