Progress and Challenges of Rail Baltica Project: Lithuanian Perspective
The Rail Baltica project in Lithuania has seen major developments in 2016, with the route from Kaunas to the Latvian border defined and EU funding secured. However, challenges remain in implementing the project smoothly, putting the joint venture RB RAIL on track, and harmonizing development plans with Baltic states and Poland. Securing EU funding beyond 2020, addressing the business case for Rail Baltica, and employing innovative financial instruments are key opportunities. The future of the project depends on various factors such as railway line reconstruction in Poland, European Commission decisions, and funding opportunities.
