The Rail Baltica project is a vital undertaking that will create a rail link between the Baltic countries and Central Europe. The new rail corridor was set to open next year but due to financial delays, it is not expected to debut until 2030. Once operational, Rail Baltica will finally re-integrate the Baltics into the European rail network and create a modern, high-speed rail link travelling through Estonia, Latvia and Lithuania to Poland. The line will enable high-speed trains to run up to four times a day from Tallinn to Warsaw at a speed of 250km/h.
The Rail Baltica project marks the symbolic return of the Baltic countries to the European family - until the Second World War the Baltic countries were already connected to their European neuighbours with 1,435 mm wide gauge. When the three countries were occupied by the Soviet Union, their rail infrastructure was changed to be in line with the the wider Russian gauge of 1,520 mm rails.
