Finland plans to change its rail track gauge to the European standard of 1,435mm, which is 89mm narrower than the current gauge. The project aims to improve security of supply and military mobility, as well as cross-border links to Sweden and Norway. The change is expected to be expensive and take decades to complete, with planning continuing until the end of the decade and construction possibly starting in 2032. The EU may fund half of the planning costs and 30% of the actual work.
