In 1860, the Astro-Hungarian Empire opened a standard (1435mm) gauge line from Pragersko (present day Slovenia) to Nagykanizsa (Hungary), completing a through connection from Ljubljana to Budapest. A short section of this line, through the town of Čakovec, lies in present day Croatia, thus making it the first railway line in the country. The next significant railway event took place in 1862, with the opening of a line from Zidani Most (Slovenia) to Sisak, via the Croatian capital, Zagreb.
The present day network has international connections with Bosnia, Hungary, Serbia and Slovenia. A short isolated section between Ploče and Metković in the south of the country connects only with the Bosnian Railways line from Sarajevo.
