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.[1][2] 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 kilometres per hour (160 mph), it will initially be limited to 200 km/h (120 mph) due to limitations of the signaling system. It is scheduled to open in 2030.[3]
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.[speculation?] It is the most modern Croatian line, capable of 160 km/h (100 mph), 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.
