Rail Baltica is building a common-gauge route through the Baltic states
The project connects a new north–south line with the European rail network.
Rail Baltica is designed to connect Estonia, Latvia and Lithuania with the European standard-gauge rail network. The project requires a new line as well as stations, connections and systems to run trains.
Track gauge is the distance between the rails. A shared gauge makes it possible for compatible trains to travel across more of the network. The wider project also has to address signalling and freight connections, which affect how the route will be used when sections open.
