Might not be news for you but I just learned about that. Finland plans to change gauge of its railway network. Reason is a EU proposal that all newly build railways in EU should have standard gauge. Finland has build the same gauge as Russia. Will take a while to switch gauges. https://en.wikipedia.org/wiki/Rail_transport_in_Finland#Conversion_to_standard_gauge
In 2022 Finland spoke against the EU proposal. In 2024 the Finnish ministry of transport and communication started an evaluation of gauge switch. In 2025 it was announced that they plan to switch.
I wonder whether Russian invasion of Ukraine has anything to do with the switch from opposition to "let's do it". #Finland#Russia#Ukraine
