High-speed rail in Croatia

With the highway construction programme in its final stages, the Croatian Parliament passed a bill to build the country's first high-speed line between Botovo, Zagreb, and Rijeka. The estimated 9.2 billion kuna ($1.6bn) project will modernize the existing Botovo–Zagreb line and construct a new line between Zagreb and Rijeka. While the line will ultimately have a maximum speed of 250 km/h, it will initially be limited to 200 km/h due to limitations of the signaling system. It is scheduled to open in 2030.

The Pan-European Corridor X, running from the Slovenian border, through Zagreb, to Serbian border is a likely future candidate for the high-speed extension to this line. It is the most modern Croatian line, capable of 160 km/h, fully electrified, and connects most branch lines in Croatia, the Croatian cities of Slavonski Brod and Vinkovci, and the Pan-European Corridor Vc towards Osijek and Bosnia and Herzegovina.
