Railways of the Slovak Republic (Slovak: Železnice Slovenskej republiky, acronym: ŽSR) is the state-owned railway infrastructure company of Slovakia. The company was established in 1993 as the successor to the Czechoslovak State Railways (Slovak: Česko-slovenské štátne dráhy) in Slovakia following the dissolution of Czechoslovakia. It had a formal monopoly on railroad transportation in Slovakia until 1996, and while other rail transport companies have since been allowed to operate in the country – for example, RegioJet, a private provider, has been operating passenger rail lines since 2012 – , it has retained a de facto monopoly.
