The project company of the high-speed rail (HSR) line Rail Baltica is using the public-private partnership (PPP) model to accelerate the development of the project and reduce the burden on state budgets. This approach follows the successful funding of the Porto – Lisbon HSR project, which received €813 million from the Connecting Europe Facility (CEF), which serves as a model for Rail Baltica as it demonstrates the feasibility of combining CEF funding with a PPP structure to close funding gaps. In the latest CEF call, Rail Baltica was granted an additional €1.2 billion for construction activities in the three Baltic States and specifically €346 million for activities in Latvia. Together with the previously granted funding, the total sum for the construction of Rail Baltica amounts to over €4 billion. The cost of the first phase of Rail Baltica, which is scheduled to be completed by 2030, is estimated at €15.3 billion.
