The ambitious Rail Baltica project aims to create a high-speed railway connecting Estonia, Latvia, and Lithuania, addressing both economic and security needs amid growing concerns over Russian aggression. Spanning 870 km, this initiative will enhance military mobility and significantly reduce travel times, yet costs have surged to €24 billion. With its completion crucial for Baltic states’ integration with Europe, Estonia’s Infrastructure Minister emphasizes its importance as a connection to European networks. As the project faces delays and criticisms over spending priorities, its realization remains vital in the context of geopolitical tensions.
